# treg: the tool catalog for your agent

**Ask for the job, not the tool.** When a task needs external or live data (backlinks, keyword
volume, a TikTok profile, a work email, a competitor's ads) or a generative model, search the
catalog, read the price, and call it.

One token reaches two kinds of tool, and treg injects the credential on the server, so you never
hold it:

- **The catalog**: curated tools treg calls for you, each by id.
- **Your own tools**: API accounts, OAuth connections, vendor CLIs and skills a teammate registered
  for the team. Never billed, with one exception: an X connection made through treg's own X
  app is billed per call, because X bills the app owner; the answer reports the price.

## First: check where you stand

How treg reached you decides the first step. Take the first case that holds; either the MCP tools
or the CLI is enough, and having both is fine.

1. **You can see treg's MCP tools** (`catalog_search`, `catalog_get`, `call`, `balance`,
   `my_tools`): treg is connected. Use them and install nothing; every `treg` command on this page
   maps onto a tool (see "Over MCP" below). A tool that answers "not authenticated" means the human
   signs in through the app's MCP or connector settings (in Claude Code: `/mcp`, pick treg,
   Authenticate).
2. **`treg` runs in your terminal**: run `treg`. It prints the account, the active team and your
   role, the balance, the team's own tools and the next commands to run; a blocker (not signed in,
   no team, an empty balance) comes first in its `help` lines. Not signed in:

   ```bash
   treg login                            # browser sign-in: GitHub, Google or an emailed code
   treg login --email you@company.com    # an emailed 6-digit code
   treg login --token <team-token>       # non-interactive, for agents and CI
   ```

3. **Neither**: treg is not set up here. Run the installer only when the human asked you to set treg
   up; otherwise give them these two ways and wait:

   ```bash
   curl -fsSL https://treg.to/install.sh | sh    # the CLI, plus this skill for every agent it detects
   treg login
   ```

   or, in an app that takes MCP servers, add `https://treg.to/mcp/` and sign in when it asks. Given a team
   token, `curl -fsSL https://treg.to/install.sh | sh -s -- --token <token>` does the install and sign-in at
   once.

Everything runs in the **active team**. Invites arrive by email: `treg invites` lists them,
`treg accept` takes one (or `treg org join <code>`); `treg org use <slug>` switches teams. A new
verified account gets $1.00 of credit once, on its first eligible team; aliases of one inbox (`+tag`,
Gmail dots) share it.

**Over MCP** (`https://treg.to/mcp/`), tools replace the CLI, and everything here maps onto them:

- search the catalog → `catalog_search`, then `catalog_get` for the exact parameters and price. On
  `verdict: none`, file `catalog_request` rather than rephrasing.
- what is new → `catalog_search` with `added_within_days` (30 is a good default) or
  `sort: "newest"`; `query` may then be empty.
- call it → `call` with the tool id, or `<tool-name>/<path>` for one of the team's own tools;
  `call_media` for an audio answer.
- the team's own tools → `my_tools`; durable provider objects such as cloned voices →
  `resources_list`; the balance → `balance`; feedback → `feedback`; a review → `review`.

## Find a tool and call it

```bash
treg catalog search "subreddit posts"                    # tools that do the job, with prices
treg catalog search --new                                # added in the last 30 days, newest first
treg catalog get scrapecreators.reddit.subreddit.posts   # parameters, price, a ready call line
treg call scrapecreators.reddit.subreddit.posts --query subreddit=news
treg catalog request "<what you need>"                   # searched and it is not there: file it
```


**For a common job, call the routed tool, not a provider you remember.** Scraping a page
(`treg.web.extract`), web search (`treg.web.search`), Google results (`treg.google.serp.organic`,
`treg.google.serp.maps`), finding or verifying an email (`treg.people.email.find`,
`treg.people.email.verify`) and most social profiles have a `treg.<capability>` tool. treg picks the
provider (the team's own key first, then the cheapest per hit), moves on when one fails or misses,
and bills only the answer it returns. The provider you used last week may not be the best one today.
Name a provider only when you need fields or options only it has.

How a routed call works:

- POST what you know about the subject, e.g. `{full_name, domain}`, `{first_name, last_name,
  domain}` or `{linkedin_url}`. The answer is `{output, raw, _treg: {served_by, tried,
  charged_micro}}`, with `X-Treg-Served-By` naming the provider.
- An error or a miss falls through to the next provider, cheapest first, within
  `X-Treg-Route-Max-Cost` (default $1 per call). A miss can be billed, which is why a routed tool
  quotes `usd_per_call: null` rather than $0: set the header for bulk runs.
  `X-Treg-Route-Waterfall: 0` stops at the first miss.
- A filter the serving provider could not apply is named in `X-Treg-Ignored-Filters` and
  `_treg.ignored_filters`: filter the rows yourself, or send `X-Treg-Route-Strict-Filters: 1` to be
  refused with an unbilled 422 instead.
- An asynchronous provider is polled for up to 60 seconds. If it is still running you get HTTP 202
  with `_treg.outcome: pending`, its poll descriptor, `reserved_micro` and `charged_micro: null`. Do
  not retry or start another provider: the task may still finish and charge.
- `catalog_get` on a routed id shows the ranked plan and its prices before you spend.

**A found contact is not a confirmed one.** An email or phone find returns the provider's best
match. Only `output.verified: true` means the mailbox was checked; otherwise `_treg.advice` names
the verify step. Run it before anyone sends, and never re-send the same find: every hit is billed,
repeats included.

- Send `X-Treg-Route-Verify: true` on `treg.people.email.find`, `treg.people.email.find.personal` or
  `treg.people.phone.find` to check each hit in the same call, as its own small charge. Read
  `_treg.verification.verdict` and follow `_treg.advice`. A live phone line does not prove the
  number is this person's.
- **Verify every address before it is sent to**, including rows from a company or domain search
  (`treg.people.search` and the like): those are directory listings, unconfirmed
  unless the row's own verification field says otherwise. `invalid` is dead, `accept_all` is risky,
  and an address the provider did not return (`info@` after an empty domain search) is a guess, not
  a result.

**Choosing between providers of one job.** `treg catalog get <id>` lists every provider of the same
job with `COST`, `WORKS` (the success rate treg observed, with its sample size), `SPEED` (median)
and `LAST OK`. Work down this order:

1. **The inputs you actually hold.** A tool that wants a `profile_url` is no substitute when you have
   a name and a domain, whatever it costs.
2. **Reliability.** A high `WORKS` on a real sample beats a rounder number on a tiny one: `99% (121)`
   is stronger evidence than `100% (8)`.
3. **Price.** Spreads inside one job reach 200×, so this is usually where the money is.
4. **`LAST OK`** breaks ties. A bare age means a real call came back; a `✓` age is the catalog's own
   verification stamp, not live traffic; `—` means nobody has verified or called it.

After a 429, a 5xx or a timeout, switch to the next provider and say which. **Never retry a 4xx
elsewhere:** it is almost always your request, and retrying spends money on several providers for
one mistake. treg does not switch providers on a direct call; only you know which inputs you hold.

**More on searching.**

- Search for the job and for any output you need: `treg catalog search "email verification
  catch-all"` finds different tools from a broad email-verification search. When you need a
  provider-specific field (catch-all, disposable, role address, SMTP), call that provider's tool:
  the routed `treg.people.email.verify` defines only `valid`, `status` and `score`.
- Discovery jobs usually come in two shapes: structured (filters such as title, location, followers,
  funding) and semantic (describe what you want). When a brief mixes hard limits with a fuzzy niche,
  run one tool of each shape and merge the results.
- A tool marked `strict_query: true` accepts only its declared query parameters, once each, with
  required fields and allowed values enforced, and no body. Rejected input is not forwarded.

**How a catalog call is served**, in this order:

1. the team registered its own tool for that provider: that tool and its key;
2. the team stored a key for the provider: that key;
3. neither, and the tool has a verified public route: no key, free;
4. otherwise treg's own account, billed to the team's balance.

Connecting a key the team already pays for takes those calls off the balance. A free public route
stays free only while you send no provider credential header yourself. A tool with no published
price is refused, not served free: connect the team's own key. A few providers that sell only
subscriptions carry a per-call rate treg set; `catalog get` says whose price it is. A team admin can
pin a job to one provider (`treg org pin`), and then calls to the job's other providers are refused.

**Calling well.**

- **A JSON body from a file:** `treg call <id> --data @body.json` (`@-` reads stdin). On Windows
  PowerShell prefer it to inline JSON, whose inner quotes PowerShell strips.
- **Scripting many calls:** use `treg --json call …`. Stdout is then one line,
  `{"result": <provider body>, "_treg": {"http_status", "call_id", "charged_micro"}}`, and nothing
  goes to stderr, so a script that merges the streams still parses every answer. `--await` is the
  exception: it prints the raw final response and writes progress to stderr, so keep the streams
  apart when you wait on a generation task. Run a handful and
  check the parsed results before looping over the whole list: a parse bug throws away answers that
  were already paid for.
- **Calling in parallel is fine**, within limits: treg sets no per-token or per-team concurrency
  limit, and provider rate limits are relayed as they are. Where treg's own account for a provider is
  at its limit of calls in progress, a team that already has calls running on it gets 429
  `share_busy`: send fewer at once, or call the routed tool, which moves on by itself.
- **Over raw HTTP**, if a body carrying SQL or HTML is refused with an HTML 403 page by the hosting
  edge before treg sees it, base64-encode the body and add `X-Treg-Body-Encoding: base64` (also
  `gzip` or `base64+gzip`). The CLI does this by itself.

## Money

**Call at the listed price without asking, then report what it cost.** Prices are visible before a
call (`treg catalog get`, MCP `catalog_get`) and most are fractions of a cent. Before a generation
task or a loop over many inputs, tell the human the expected total, then keep a running sum of
`X-Treg-Cost-Micro` and stop before it passes what they agreed to. `X-Treg-Route-Max-Cost` caps
each call, not the loop.

- **Read the `cost` block, not only the headline.** `per_call` is flat. `type: per_result` with
  `unit: row` is priced per returned row, and its `~$/call` figure assumes a 20-row page (your
  `limit` sets the real count). `unit: target`, `domain` or `keyword` is priced per thing you ask
  about: one unit per target whatever the page size, so a body listing ten domains reserves ten.
- **What you were charged** is the response header `X-Treg-Cost-Micro` (integer micro-USD; `cost_usd`
  over MCP), never anything in the provider's body. Keep `X-Treg-Call-Id` with it: it is the id to
  quote, and `GET https://treg.to/calls/<call id>/result` returns the stored answer of a successful catalog
  call you lost. The CLI prints `treg: charged $<usd> · call id <id>` on stderr; stdout is always
  the exact body. On an asynchronous submission (a generation task) the header is the **reserved**
  amount, not a charge: the task settles the real one when it succeeds and refunds it all when it
  fails, so report it as reserved until the task is done.
- **A hard ceiling per call:** `X-Treg-Route-Max-Cost: <usd>` refuses a call whose reservation would
  exceed it (402 `route_max_cost`, nothing charged). Where the catalog says the provider accepts a
  ceiling parameter, treg also forwards the remaining ceiling upstream, so a provider that fails
  over to a dearer source cannot settle above it; a refusal from that parameter is a non-2xx and
  costs nothing. For every other provider the header stays a pre-reservation guard. It applies to
  each request on its own and does not add up across calls. Direct calls have no default; on a
  routed call it also bounds the whole waterfall, $1 by default, and each child receives the
  unspent remainder.
- **Failed calls are free.** A 4xx or 5xx relayed from the provider costs nothing. Empty results mean
  whatever the provider means by them; treg relays and does not normalise. A provider that reports
  a failure inside a 2xx (a DataForSEO task status other than 20000) is flagged with
  `X-Treg-Upstream-Failed` (`upstream_failed` over MCP): the body has no result, and the charge is
  what the provider billed for the attempt.
- **Repeat questions are cheaper.** An answer may come from treg's archive of the same question
  (`X-Treg-Cache: hit`): the team's first call on a question costs full price, later hits 10%, and
  hits on the team's own key nothing. `Cache-Control: no-cache` forces a live call.
- **A "free" tool can still bill** when treg's own account for its provider runs out and the call is
  relayed (`X-Treg-Served-Via: overflow:<name>`): if `catalog_get` shows `overflow_price_usd`, quote
  that price.
- `treg balance` shows the balance and recent charges, and the dashboard's Activity page shows the
  settled cost of every call. `treg topup` adds funds or sets up automatic top-ups.

## When a call fails

treg's own refusals carry the header `X-Treg-Error: 1` (`whose_error: treg` over MCP); without it,
the status and body are the provider's. The CLI names whose answer it was on stderr. A bare 5xx with
no JSON `detail` is never treg's.

| you see | charged | what to do |
|---|---|---|
| a 4xx from the provider, other than 429 | no | Fix your request. Do not retry it with another provider. |
| a 429 or 5xx from the provider | no | Try the next provider of the job, and say which. |
| a timeout or dropped connection on your side | maybe | The provider may have answered and been paid. Repeat with the same `Idempotency-Key`; see below. |
| 403 `capability_pinned` | no | A team admin pinned this job to one provider. Call `use_endpoint` from the body instead. |
| 402 `insufficient_balance` | no | The body has `balance_micro`, `estimated_cost_micro`, `topup_url`. Check `treg balance`, then top up (`treg topup`, or the dashboard's Team → Billing) or connect the team's own key for that provider. |
| 402 `route_max_cost` | no | Your `X-Treg-Route-Max-Cost` refused it. Ask for fewer rows or targets, or raise the ceiling. |
| 429 `share_busy` | no | treg's account for that provider is at its limit and your team already has calls running on it. Send fewer at once, retry after `retry_after_s`, or call the routed tool. |
| 429 `trial_allowance_reached` | no | A free trial pool on treg's key is used up for today; it resets at 00:00 UTC. Connect the team's own key. |
| 503 `provider_capacity_unavailable` | no | treg's own account for that provider is out. Take one of the body's `alternatives`, use the team's own key, or retry after `resets_at` or a minute. |
| `X-Treg-Capacity: exhausted` on any status | not when `X-Treg-Cost-Micro` is `0` | treg's own account for that tool refused for want of credit. Not your balance; try another tool. |
| 502 `route_failed` | `charged_micro` in the body | Every provider of a routed call failed or missed; `tried` lists them. Misses can be billed: read `charged_micro` before running it again. |
| 409, 410 with an `idempotency_*` error | see below | See "Retrying without paying twice". |

Any other refusal from treg (a paused provider, treg itself busy, an answer over its size limit, an
old CLI) charged nothing, and its body's `message` says what to do.

## Retrying without paying twice

A failed call (a 4xx or 5xx relayed from the provider) was never billed: fix it, or try another
provider. A timeout or a dropped connection on your side is different: the provider may have
answered and been paid before the answer was lost. Send an `Idempotency-Key` header
(`idempotency_key` over MCP) on any call you may need to repeat, and repeat it with the same key.
treg returns the stored answer, does not call the provider again and charges nothing; the reply
carries `X-Treg-Idempotent-Replay: true` (`replayed: true` over MCP), `X-Treg-Cost-Micro: 0`, and the
first call's charge in `X-Treg-Original-Cost-Micro`.

- Use a new idempotency key, or none, for new work, even with the same parameters: asking again to
  see what changed is a new call, and the old key would hand back the old answer. Reusing one for a
  different request is refused (422).
- Idempotency keys belong to the caller and last 24 hours; a call that fails frees its key at once.
- 409: the original call is still running; retry shortly.
- 410 (`idempotency_response_lost`, `idempotency_response_too_large` over the 2 MB replay limit,
  `idempotency_outcome_unknown`): the first call was, or may have been, charged and its answer was
  not kept. The body names the `call_id`; `GET https://treg.to/calls/<call id>` shows the cost and
  `/result` any stored answer. A new idempotency key calls again.

## Generate video, images, voice or music

Generation models are in the catalog under the `video-gen`, `image-gen`, `voice-gen` and `music-gen`
platforms, one row per model per route, so one model on two routes sits beside itself with both
prices. Models are not interchangeable: you pick one, treg does not.

```bash
treg catalog search "text to video"                  # every model, with prices
treg catalog get minimax.video-gen.h3.generate       # native parameters, model enum, price, a ready call line
treg call minimax.video-gen.h3.generate --await --timeout 900 --data @body.json
```

- **Video and image generation is an asynchronous task.** The submission reserves the price and
  returns a task id at once; it is charged only if the task succeeds, and a failed or moderated task
  refunds the whole hold. `--await` waits and prints the final response; if the wait is cut off, the
  task and the money are not lost, and the CLI prints the command that resumes it.
- **CLI agents: raise your shell tool's timeout or run the call in the background.** A video takes
  1-5 minutes, and a default 2-minute command limit cuts the wait off.
- **MCP and raw HTTP:** the response header `X-Treg-Async` is the descriptor: where to poll, which
  statuses are final, where the result is. Wait about 60 s before the first check, then every
  30-60 s; three to six checks per video is normal. Do other work in between.
- A first answer that is already final (an email verification often is) is charged as one call.
- **Result URLs expire** (the descriptor's `ttl_note` says when). Download
  promptly: treg never stores generated media. On some routes the file needs one more call, and
  `--await` prints that command.
- **Reference media** (a face, a voice clip, a first frame) must be at a public URL the vendor can
  fetch. Paste hosts fail vendor probes at random; `treg host face.jpg` prints a public URL (30 MB,
  7 days, free) to put in `image_urls` or `audio_urls`.
- **Binary answers** (speech from some providers): redirect stdout to a file, or use MCP
  `call_media`. Provider objects the team created, such as cloned voices, are listed by
  `treg resources list --provider <provider>` (MCP `resources_list`).
- A tool whose answer inlines media as base64 (Google AI's images, speech and Lyria music) may answer
  up to 64 MiB and is charged from the provider's reported usage. Its answer is never replayed: an
  `Idempotency-Key` retry generates, and bills, a new one.
- Parameters are the provider's own, verbatim. Nothing is translated between providers.

## Your own tools

**Start from what the team registered, then use each API exactly as its own docs say.**

```bash
treg tool ls                                  # the team's tools: names, hosts, which credential goes where
treg call intercom conversations?per_page=5   # <tool-name> and the upstream path
```

Over HTTP that is `https://treg.to/call/<tool-name>/<path>`, or the upstream URL behind the prefix,
`https://treg.to/call/https://api.intercom.io/me`, with `X-Treg-Token: <token>`. With a personal sign-in
token, also send `X-Treg-Org: <team-slug>`; a team token does not need it. treg finds the tool,
injects the team's credential on the server, and relays method, query, headers and body unchanged;
your `X-Treg-Token` is removed before the provider sees the request. `GET https://treg.to/tools` lists the
tools as JSON.

**Command-line tools** (stripe, gh, vercel, gcloud and others) run with the team's credential and
without you logging in:

- `treg <command>` is the simplest: `treg claude`, `treg node server.js`, `treg with -- npm test`
  run that one command with the team's credentials, and nothing else changes. Calls to a registered
  host are credentialed by the server; every other address goes out untouched. Node before version
  24 ignores proxy settings in its built-in `fetch`, so such a call goes out with no credential: use
  a client that reads the environment (axios, got, undici `ProxyAgent`) or Node 24+. curl, git,
  Python requests and httpx, and Deno are covered at any version.
- `treg run stripe -- balance retrieve` runs one vendor CLI. `--local` (the default) runs it on this
  machine, isolated under a dedicated user once an admin has run `sudo treg setup-local-run`;
  server-side execution (`--server`) is disabled globally.
- `treg shell start` opens a subshell where registered CLIs get their credentials by themselves;
  `--proxy` also credentials HTTPS calls your own code makes to a registered API. `treg serve` runs
  the same proxy as a background service. A certificate-pinned client refuses the interception: use
  `treg run` or `treg call` for it.

[Import and shell](https://treg.to/tutorial-import-shell.md) has the full walkthrough.

**Connecting a key for catalog calls.** `treg connections connect --provider <provider>` connects a
provider the catalog knows: a consent screen for OAuth providers; for key-based ones a hidden
prompt, or the key piped with `--key-stdin`. treg verifies it first. From then on the team's calls
to that provider use its key and are never billed.

## Share keys and skills with the team

**Bulk is fastest.** In the directory the human names, `treg scan` lists the provider keys it
recognises in `.env` and the skills in the subfolders, and sends nothing; `treg upload --select
<names>` registers the ones the human picks. Without a terminal, `treg upload` refuses unless given
`--select` or `--all`.

**Wrap a new key in a skill**, so the credential, the tool and the recipe land together. If none
exists, write a basic one: a SKILL.md with frontmatter (agents find skills by it) and one example
call.

```bash
mkdir -p ./posthog && cat > ./posthog/SKILL.md <<'MD'
---
name: posthog
description: Query the PostHog analytics API through treg; the key is injected on the server. Use for events, insights and project queries.
---
Call it: `treg call posthog api/projects/@current` (upstream: https://us.posthog.com)
MD
treg skill init --dir ./posthog   # drafts treg.json (base URL, the secrets); review it and add the key
treg skill add --dir ./posthog    # registers the recipe, the secret and the tool together
```

Without a recipe: `treg secret add`, then `treg tool add --secret <name>`; never store a key that no
tool binds. A key in the query string, several credentials on one tool, and OAuth tokens are covered
by `treg tool add --help`, `treg secret add --help` and `treg skill --help`. Hosted OAuth
(`treg oauth connect`) needs `https://treg.to/oauth/callback` among the OAuth app's redirect URIs.

A teammate's agent then calls the tool without holding the credential, and each call is logged
against its own token. `treg skill install <name>` writes a shared skill into the agent's skills
folder.

## Run the team

`treg calls` and `treg audit` show who called what, with results and costs; `treg health --run`
re-checks every credential. `treg org --help` lists the team commands (create, invite, members, use,
pin). Roles: a viewer calls tools and reads; a member also registers and manages their own; an admin
manages anyone's and invites; an owner also changes roles and deletes the team.

**Give an agent its own token** (admin+) instead of the human's: `treg org agent-new <name>` prints
it once, and `--tools`, `--cap` and `--pin` limit it (`treg org agent-new --help`). Put it in the
agent's `TREG_TOKEN`. An agent token calls the team's tools and reads; it can never sign in, create
a team or own one. If you are an agent with a token of your own, use it rather than the machine
owner's: your calls then appear under your own name.

## Feedback and reviews

Report problems and suggestions about treg as you meet them, small ones included (unclear
instructions, confusing results or charges, unhelpful errors, workarounds), even when the task
succeeded: `treg feedback submit <quality|pricing|friction|other> "message" --call-id <id>`, or MCP
`feedback`. Report each issue once, keep private information out, then carry on. See
[feedback instructions](https://treg.to/feedback.md).

When a result invites a review, rate that call after using it: `treg review CALL_ID USEFULNESS
[--reason "..."]` or MCP `review`, with `useful`, `partly`, `not_useful` or `not_sure`. A reason may
be quoted on the tool's catalog page without naming your team, so write about the tool.

## Rules

- **Follow the next step an answer names**: a `help` line, `_treg.advice`, an error body.
- **Never ask for or paste a provider key.** Register it once; the team calls it without holding it.
- **Keys are write-only.** No one can read a stored value back, you included. A tool may use a key a
  teammate shared with the team: you spend it without seeing it, and every call is logged against
  the token that made it.
- **Everything is scoped to the active team.** A token reaches that team's tools and nobody else's.
- **treg relays, it does not interpret.** A provider's status and body are the provider's truth.
- More: `https://treg.to/llms.txt` (the overview) and the [tutorial](https://treg.to/tutorial.md).
