Alpaca brokerage — US stocks & ETFs. Account, positions, orders, quotes, history, and order placement (paper + live). Use when the user wants to check or trade a US-stock account on Alpaca (e.g. "Alpaca buying power", "buy 1 AAPL on Alpaca paper", "my Alpaca positions"). Cloud API, runs directly in the container.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## What this is ☁️ **Cloud broker** — Alpaca exposes a public REST API, so this runs **directly in the Starchild container**, no local gateway needed. US equities and ETFs. Paper and live are fully separated: **different key pairs, different hosts** (`paper-api.alpaca.markets` vs `api.alpaca.markets`). A paper key physically cannot touch the live account. Live order placement additionally requires the `--confirm-live` flag. ## Get your API keys 1. Sign up at [alpaca.markets](https://alpaca.markets) (US brokerage; paper trading is free and needs no funding). 2. **Paper keys:** log in → switch to **Paper Trading** (toggle top-left) → **Home** → "API Keys" panel → **Generate New Keys**. Copy the **Key ID** and **Secret Key** (secret shown once). 3. **Live keys (optional, real money):** switch to **Live Trading** → same API Keys panel → generate. These are a *different* pair from paper. 4. Market data: the free **IEX** feed works out of the box. **SIP** (full-market) needs a paid data subscription. ## Configure (.env) Request via secure input — never paste keys in chat. Variables: | Variable | Required | Notes | |---|---|---| | `ALPACA_API_KEY` | yes (paper) | paper Key ID | …

How to install
mdr add starchild-ai-agent/official-skills/alpaca@sha256:a08f909a2c270494The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
