# Adaptyv Bio Foundry API
- Adaptyv Bio is a cloud lab that turns protein sequences into experimental data. Users submit amino acid sequences via API or UI; Adaptyv's automated lab runs assays (binding, thermostability, expression, fluorescence) and delivers results in ~21 days.
-
- **Official docs:** [docs.adaptyvbio.com/api-reference](https://docs.adaptyvbio.com/api-reference) · [llms.txt index](https://docs.adaptyvbio.com/llms.txt) · [OpenAPI spec](https://devs.adaptyvbio.com/api/v1/openapi.json)
-
- ## Quick Start
+ Use this skill to turn protein sequences into experimentally measured data through
+ Adaptyv's cloud laboratory. Confirm the target construct, assay conditions, controls,
+ and replicate plan before submitting a batch; turnaround depends on the experiment.
- **Base URL:** `https://devs.adaptyvbio.com/api/v1`
+ Reviewed against the deployed [OpenAPI schema](https://devs.adaptyvbio.com/api/v1/openapi.json)
+ (`info.version: 0.0.2`) and official SDK `0.1.0` at commit
+ `cdf207819ed5a58e0c127453626d2bce125c8064`. The schema version alone does not identify
+ all changes. See the [endpoint reference](references/api-endpoints.md) for current
+ request/response details and discrepancies in upstream examples.
- **Authentication:** Bearer token in the `Authorization` header. Tokens are created in [the Foundry portal](https://foundry.adaptyvbio.com/) under Organization → Settings → Tokens.
+ ## Connect
- When writing code, always read the API key from the environment variable `ADAPTYV_API_KEY` or from a `.env` file — never hardcode tokens. Check for a `.env` file in the project root first; if one exists, use a library like `python-dotenv` to load it.
+ **Base URL:** `https://devs.adaptyvbio.com/api/v1`. The schema is at
+ `/openapi.json`; never append that filename to normal endpoint requests.
- The [official API docs](https://docs.adaptyvbio.com/api-reference/api-introduction) use `FOUNDRY_API_TOKEN` in curl examples; that is the same bearer token — prefer `ADAPTYV_API_KEY` in Python and new shell scripts for consistency with the SDK.
+ Create a bearer token in [Foundry](https://foundry.adaptyvbio.com/) under
+ Organization → Settings → Tokens. Use Viewer for reads and Member for experiment
+ writes. Read credentials from `ADAPTYV_API_KEY`; the documentation's
+ `FOUNDRY_API_TOKEN` is an alternative variable name for the same token. If using a
+ project `.env`, explicitly call `python-dotenv.load_dotenv()` before SDK setup;
+ the SDK does not load that file automatically. Never print or commit tokens.
```bash
- export ADAPTYV_API_KEY="abs0_..."
- curl https://devs.adaptyvbio.com/api/v1/targets?limit=3 \
+ # ADAPTYV_API_KEY is already set in the environment.
+ curl --fail-with-body 'https://devs.adaptyvbio.com/api/v1/targets?limit=3' \
-H "Authorization: Bearer $ADAPTYV_API_KEY"
```
- Every request except `GET /openapi.json` requires authentication. Store tokens in environment variables or `.env` files — never commit them to source control.
-
- The authenticated examples below are illustrative and require real sequences, target IDs,
- and account access. The API base ends at `/api/v1`; do not append `/openapi.json`
- to endpoint requests. The public schema URL is for schema discovery only.
+ Resource endpoints require bearer authentication. The schema and liveness endpoint
+ `GET /info/health` are public. `GET /whoami` reports the active organization and
+ permissions; check it when account scope is unclear.
## Python SDK
- **Version note:** `adaptyv-sdk` **0.1.0** (beta) is not yet on PyPI — install from GitHub:
-
- ```bash
- uv pip install "git+https://github.com/adaptyvbio/adaptyv-sdk.git"
- ```
-
- In a project with `pyproject.toml`:
-
- ```bash
- uv add "adaptyv-sdk @ git+https://github.com/adaptyvbio/adaptyv-sdk.git"
- ```
-
- **Environment variables** (set in shell or `.env` file):
+ Install the reviewed revision in your project environment (requires Python 3.11+):
```bash
- ADAPTYV_API_KEY=your_api_key
- ADAPTYV_API_URL=https://devs.adaptyvbio.com/api/v1
- ADAPTYV_ORGANIZATION_ID=your_org_id # optional
+ uv pip install "git+https://github.com/adaptyvbio/adaptyv-sdk.git@cdf207819ed5a58e0c127453626d2bce125c8064"
```
- The `@lab.experiment` decorator and `FoundryClient` both read `ADAPTYV_API_KEY` and `ADAPTYV_API_URL` from the environment when not passed explicitly.
-
- ### Decorator Pattern
-
- ```python
- from adaptyv import lab
-
- @lab.experiment(target="PD-L1", experiment_type="screening", method="bli")
- def design_binders():
- return {"design_a": "MVKVGVNG...", "design_b": "MKVLVAG..."}
+ Import from `adaptyv`, not `adaptyv_sdk`. `FoundryClient` requires explicit `api_key`
+ and `base_url`; the `lab` convenience object reads `ADAPTYV_API_KEY` and
+ `ADAPTYV_API_URL`. Set the latter to the base URL above to override the SDK's
+ older hostname default.
- result = design_binders()
- print(f"Experiment: {result.experiment_url}")
- ```
+ The following examples are illustrative for authenticated use. Their request
+ construction and parsing were checked with mocked HTTP responses, not a paid lab
+ run. Replace environment inputs with real, reviewed sequence data and catalog IDs.
- ### Client Pattern
+ ### Browse, estimate, create a draft
```python
+ import json
import os
+ from pathlib import Path
from adaptyv import FoundryClient
client = FoundryClient(
api_key=os.environ["ADAPTYV_API_KEY"],
- base_url=os.environ.get(
- "ADAPTYV_API_URL",
- "https://devs.adaptyvbio.com/api/v1",
- ),
+ base_url="https://devs.adaptyvbio.com/api/v1",
)
- # Browse targets
- targets = client.targets.list(search="EGFR", selfservice_only=True)
-
- # Estimate cost
- estimate = client.experiments.cost_estimate({
- "experiment_spec": {
- "experiment_type": "screening",
- "method": "bli",
- "target_id": "target-uuid",
- "sequences": {"seq1": "EVQLVESGGGLVQ..."},
- "n_replicates": 3
- }
- })
-
- # Create and submit
- exp = client.experiments.create({...})
- client.experiments.submit(exp.experiment_id)
-
- # Later: retrieve results
- results = client.experiments.get_results(exp.experiment_id)
- ```
-
- ## Experiment Types
+ # Review vendor, catalog number, construct, and pricing before selecting an ID.
+ targets = client.targets.list(search="EGFR", selfservice_only=True, detailed=True)
+ for target in targets.items:
+ print(target.id, target.name, target.vendor_name, target.catalog_number)
- | Type | Method | Measures | Requires Target |
- |---|---|---|---|
- | `affinity` | `bli` or `spr` | KD, kon, koff kinetics | Yes |
- | `screening` | `bli` or `spr` | Yes/no binding | Yes |
- | `thermostability` | — | Melting temperature (Tm) | No |
- | `expression` | — | Expression yield | No |
- | `fluorescence` | — | Fluorescence intensity | No |
+ # candidates.json is a map of unique names to full amino acid sequences.
+ sequences = json.loads(Path("candidates.json").read_text())
+ spec = {
+ "experiment_type": "screening",
+ "method": "bli",
+ "target_id": os.environ["ADAPTYV_TARGET_ID"],
+ "sequences": sequences,
+ "n_replicates": 3,
+ }
- ## Experiment Lifecycle
+ # SDK takes the spec itself; REST takes {"experiment_spec": spec}.
+ estimate = client.experiments.cost_estimate(spec)
+ if estimate.breakdown is None:
+ raise ValueError("Incomplete estimate: review warnings and obtain a full quote")
+ print("Estimated USD cents, excluding VAT:", estimate.breakdown.total_cents)
- ```
- Draft → WaitingForConfirmation → QuoteSent → WaitingForMaterials → InQueue → InProduction → DataAnalysis → InReview → Done
+ # After the batch and estimated cost have been reviewed:
+ exp = client.experiments.create(name="EGFR binder screen batch 1", experiment_spec=spec)
+ experiment_id = exp.experiment_id
+ client.close()
```
- | Status | Who Acts | Description |
- |---|---|---|
- | `Draft` | You | Editable, no cost commitment |
- | `WaitingForConfirmation` | Adaptyv | Under review, quote being prepared |
- | `QuoteSent` | You | Review and confirm the quote |
- | `WaitingForMaterials` | Adaptyv | Gene fragments and target ordered |
- | `InQueue` | Adaptyv | Materials arrived, queued for lab |
- | `InProduction` | Adaptyv | Assay running |
- | `DataAnalysis` | Adaptyv | Raw data processing and QC |
- | `InReview` | Adaptyv | Final validation |
- | `Done` | You | Results available |
- | `Canceled` | Either | Experiment canceled |
-
- The `results_status` field on an experiment tracks: `none`, `partial`, or `all`.
+ `create(name=..., experiment_spec=...)` does not accept a single REST-body dictionary.
+ `cost_estimate(spec)` wraps the spec itself; do not wrap it a second time.
+ For an affinity experiment, the SDK additionally requires explicit
+ `antigen_concentrations`, even though REST supplies a default when omitted.
- ## Common Workflows
+ ### Submit, then inspect and confirm the quote
- ### 1. Submit a Binding Screen (Step by Step)
+ With a configured client and the saved `experiment_id`:
```python
- # 1. Find a target
- targets = client.targets.list(search="EGFR", selfservice_only=True)
- target_id = targets.items[0].id
+ client.experiments.submit(experiment_id)
+ # Quote generation is asynchronous. Retry get_quote with a bounded timeout if it
+ # returns 404 after successful submission; a draft has no forthcoming quote.
+ quote = client.experiments.get_quote(experiment_id)
+ print(quote.amount_total, quote.currency, quote.expires_at)
- # 2. Preview cost
- estimate = client.experiments.cost_estimate({
- "experiment_spec": {
- "experiment_type": "screening",
- "method": "bli",
- "target_id": target_id,
- "sequences": {"seq1": "EVQLVESGGGLVQ...", "seq2": "MKVLVAG..."},
- "n_replicates": 3
- }
- })
+ # Once the quote is accepted within the user's authorized scope:
+ accepted = client.experiments.confirm_quote(experiment_id)
+ print(accepted.invoice_id, accepted.hosted_invoice_url)
+ ```
- # 3. Create experiment (starts as Draft)
- exp = client.experiments.create({
- "name": "EGFR binder screen batch 1",
- "experiment_spec": {
- "experiment_type": "screening",
- "method": "bli",
- "target_id": target_id,
- "sequences": {"seq1": "EVQLVESGGGLVQ...", "seq2": "MKVLVAG..."},
- "n_replicates": 3
- }
- })
+ Confirmation creates/finalizes an invoice; it does not settle payment. Use the
+ returned hosted invoice URL or the current REST payment pointer. SDK 0.1.0 does
+ not expose invoice payment, organization webhooks, or `whoami` helpers.
- # 4. Submit for review
- client.experiments.submit(exp.experiment_id)
+ Avoid the reviewed SDK's `lab.experiment(target="EGFR")` shortcut: it passes only
+ UUID-shaped targets and does not resolve a target name. `auto_confirm=True` and
+ `lab.confirm_experiment()` call submission, not the quote-confirm endpoint. Use
+ the explicit client methods above. The decorator also supplies `method` for
+ non-binding experiments, which the current API rejects.
- # 5. Poll or use webhooks until Done
- # 6. Retrieve results
- results = client.experiments.get_results(exp.experiment_id)
- ```
+ ### Retrieve every result without losing fields
- ### 2. Automated Pipeline (Skip Draft + Auto-Accept Quote)
+ The SDK's generated models predate some live result fields and may discard them.
+ Use REST JSON when archiving results, target references, or newer kinetic fits:
```python
- exp = client.experiments.create({
- "name": "Auto pipeline run",
- "experiment_spec": {...},
- "skip_draft": True,
- "auto_accept_quote": True,
- "webhook_url": "https://my-server.com/webhook"
- })
- # Webhooks report customer-facing updates; poll experiment status for completion
+ import json
+ import os
+ from pathlib import Path
+ import httpx
+
+ experiment_id = os.environ["ADAPTYV_EXPERIMENT_ID"]
+ with httpx.Client(
+ base_url="https://devs.adaptyvbio.com/api/v1",
+ headers={"Authorization": f"Bearer {os.environ['ADAPTYV_API_KEY']}"},
+ timeout=30,
+ ) as api:
+ response = api.get(f"/experiments/{experiment_id}")
+ response.raise_for_status()
+ experiment = response.json()
+ if experiment["results_status"] != "all":
+ raise RuntimeError("Results are not complete; inspect status before analysis")
+ results, offset = [], 0
+ while True:
+ response = api.get(f"/experiments/{experiment_id}/results",
+ params={"limit": 100, "offset": offset})
+ response.raise_for_status()
+ page = response.json()
+ results.extend(page["items"])
+ offset += len(page["items"])
+ if not page["items"] or offset >= page["total"]:
+ break
+ Path("foundry-results.json").write_text(json.dumps(
+ {"experiment": experiment, "results": results}, indent=2
+ ))
```
- ### 3. Using Webhooks
+ Archive raw data packages when available, plus sequence/target identities, assay
+ method, units, conditions, replicate measurements and fit quality. Null kinetic
+ values are missing/unresolved measurements, not zero. A screening binding call is
+ not a measured affinity. Compare KD values only under compatible assay conditions;
+ the schema's `kd_mean` averages strong-binding replicates and is not an unbiased
+ summary of every tested replicate.
- Pass `webhook_url` when creating an experiment. The current [webhook contract](https://docs.adaptyvbio.com/api-reference/api-introduction#webhooks) sends `experiment_update` events for customer-facing updates, not a guaranteed stream of every status transition. Verify `X-Adaptyv-Signature` as HMAC-SHA256 over the unmodified request body using the webhook secret, and make processing idempotent using the update identifier. Acknowledge with `2xx`; network errors and `5xx` responses are retried up to three times. Poll `GET /experiments/{id}` and inspect `results_status` before treating results as complete.
+ ## Experiment types and validation
- ## Sequences
+ | `experiment_type` | `method` | `target_id` | Sequence count | Replicates |
+ |---|---|---|---|---|
+ | `affinity` | Required: `bli` or `spr` | Required | At least 1 | Optional, 1–5; default 3 |
+ | `screening` | Required: `bli` or `spr` | Required | At least 1 | Optional, 1–5; default 3 |
+ | `thermostability` | Omit | Omit | At least 1 | Optional, 1–5; default 3 |
+ | `expression` | Omit | Omit | At least 1 | Optional, 1–5; default 3 |
+ | `fluorescence` | Omit | Omit | At least 1 | Optional, 1–5; default 3 |
+ | `epitope_binning` | Omit | Required | 4–28, multiple of 4 | Omit |
+ | `enzyme_activity` | Omit | Omit | At least 1 | Optional, 1–5; default 3 |
- - Simple format: `{"seq1": "EVQLVESGGGLVQPGGSLRLSCAAS"}`
- - Rich format: `{"seq1": {"aa_string": "EVQLVESGGGLVQ...", "control": false, "metadata": {"type": "scfv"}}}`
- - Multi-chain: use colon separator — `"MVLS:EVQL"`
- - Valid amino acids: A, C, D, E, F, G, H, I, K, L, M, N, P, Q, R, S, T, V, W, Y (case-insensitive, stored uppercase)
- - Sequences can only be added to experiments in `Draft` status
+ Inapplicable fields are rejected. `antigen_concentrations` is affinity-only, in nM;
+ REST's default is `[1000.0, 316.2, 100.0, 31.6, 0.0]`. `parameters` holds optional
+ assay settings; coordinate any nonstandard configuration with the laboratory.
- ## Filtering, Sorting, and Pagination
+ Sequences accept full strings or rich entries such as
+ `{"candidate": {"aa_string": "EVQLVESGGGLVQPGGSLRLSCAAS", "control": false}}`.
+ Use the 20 standard amino acid letters; inputs are case-insensitive and stored
+ uppercase. Colons separate chains. Ellipses are not valid sequence characters.
+ Rich creation metadata is constrained by `SequenceMetadata`, not arbitrary JSON:
+ use `SingleChain`, `ScFv`, `FAB`, or `IgG`; ScFv needs `VH` and `VL`, FAB needs
+ `framework_regions.ch` and `.cl`. The SDK accepts the schema's Portal-style enum
+ values. Add sequences through `POST /sequences` only while status is `draft`.
- All list endpoints support pagination (`limit` 1-100, default 50; `offset`), search (free-text on name fields), and sorting.
+ ## Lifecycle and updates
- **Filtering** uses s-expression syntax via the `filter` query parameter:
- - Comparison: `eq(field,value)`, `neq`, `gt`, `gte`, `lt`, `lte`, `contains(field,substring)`
- - Range/set: `between(field,lo,hi)`, `in(field,v1,v2,...)`
- - Logic: `and(expr1,expr2,...)`, `or(...)`, `not(expr)`
- - Null: `is_null(field)`, `is_not_null(field)`
- - JSONB: `at(field,key)` — e.g., `eq(at(metadata,score),42)`
- - Cast: `float()`, `int()`, `text()`, `timestamp()`, `date()`
+ Wire status values are lowercase snake case:
- **Sorting** uses `asc(field)` or `desc(field)`, comma-separated (max 8):
- ```
- sort=desc(created_at),asc(name)
+ ```text
+ draft -> waiting_for_confirmation -> quote_sent -> waiting_for_materials
+ -> in_queue -> in_production -> data_analysis -> in_review -> done
```
- **Example:** `filter=and(gte(created_at,2026-01-01),eq(status,done))`
+ `canceled` is also possible. `results_status` is independently `none`, `partial`,
+ or `all`. Inspect it before treating a result set as complete. Most experiment
+ PATCH fields are editable in `draft` or `in_review`; `webhook_url` remains editable
+ at any status. A sequence PATCH replaces the sequence list; `POST /sequences`
+ appends to a draft.
- ## Error Handling
+ Create-time REST flags `skip_draft` and `auto_accept_quote` enable automation;
+ `auto_accept_quote` implies `skip_draft` and requires full pricing. They can commit
+ the batch to laboratory processing and billing, so use them only within the
+ user's approved experiment/budget scope. The SDK's public `create()` method does
+ not expose `auto_accept_quote`, `webhook_secret`, or the payment selector; use the
+ REST contract in the reference when these fields are needed.
- All errors return:
- ```json
- {
- "error": "Human-readable description",
- "request_id": "req_019462a4-b1c2-7def-8901-23456789abcd"
- }
- ```
- The `request_id` is also in the `x-request-id` response header — include it when contacting support.
+ For signed delivery, set a per-experiment `webhook_url` and `webhook_secret`
+ (minimum 32 characters) at creation, or register an organization webhook. Store
+ the secret when setting it; it is write-only. An experiment webhook overrides
+ organization delivery. Verify `X-Adaptyv-Signature` (`sha256=<hex>`) as HMAC-SHA256
+ over the raw body with constant-time comparison. Events are `experiment_update`
+ customer-facing updates, not a complete stream of status transitions. Deduplicate
+ by `data.update_id`; `delivery_id` identifies an attempt. Return `2xx`; network
+ failures and `5xx` retry up to three times, while `4xx` is permanent. Continue to
+ poll status/results if delivery is missing.
- ## Token Management
+ ## Lists, filters and errors
- Tokens use Biscuit-based cryptographic attenuation. You can create restricted tokens scoped by organization, resource type, actions (read/create/update), and expiry via `POST /tokens/attenuate`. Revoking a token (`POST /tokens/revoke`) revokes it and all its descendants.
+ Paginated endpoints return `{items, total, count, offset}`; use `limit` 1–100
+ (default 50) and `offset` (default 0). Fetch all pages. Query support varies by
+ endpoint: sequence lists lack `filter`, token lists only paginate, and organization
+ webhooks return an unpaginated array. See the endpoint reference.
- ## Detailed API Reference
+ Where supported, filters use `eq(field,value)`, `neq`, `gt`, `gte`, `lt`, `lte`,
+ `contains`, `between`, `in`, `is_null`, `is_not_null`, combined with `and`, `or`,
+ `not`. Example: `and(gte(created_at,2026-01-01),eq(status,done))`. Sorting accepts
+ `asc(field)` / `desc(field)` (up to eight comma-separated terms), `-field` / `+field`,
+ or `field:asc` / `field:desc`. Use the HTTP client's query encoder. Advanced
+ expressions support `at(field,key)` and casts (`float`, `int`, `text`, `timestamp`,
+ `date`), subject to each endpoint's allowed fields.
- For the full list of all 32 endpoints with request/response schemas, read `references/api-endpoints.md`.
+ Structured errors generally include `error` and `request_id`; record the
+ `x-request-id` header for support. Handle non-JSON transport failures too. Check
+ status before retrying mutations after an ambiguous timeout: the server may
+ already have created the experiment or accepted a quote. The SDK retries 429/5xx
+ responses; its retries do not establish mutation idempotency.
+
+ Token attenuation only narrows permissions. `POST /tokens/revoke` revokes the
+ calling token's **root family**, including siblings descended from that root,
+ even when authenticating with an attenuated token.
