# Alpaca Broker API — Trading on Behalf of Accounts Place, modify, cancel, and track orders for an end-user account, and read positions & buying power. The defining feature of Broker API trading: **`account_id` is in the path** — you act *for* a user account, not your own. > Read `alpaca-broker-integration` first. Broker API + HTTP Basic auth. (The standalone Trading API uses `/v2/orders` with no account in the path; everything else here transfers.) ## Reference - Guides: `https://docs.alpaca.markets/docs/orders-at-alpaca`, `https://docs.alpaca.markets/docs/fractional-trading` - API ref: `https://docs.alpaca.markets/reference/postorder` - Live schema: `alpaca-docs` MCP → `get-endpoint` title `"Broker API"` path `/v1/trading/accounts/{account_id}/orders` ## 1. Endpoints | Method | Path | Purpose | |--------|------|---------| | POST | `/v1/trading/accounts/{id}/orders` | Create order | | GET | `/v1/trading/accounts/{id}/orders` | List orders (filter by `status`, `symbols`, `after`…) | | GET | `/v1/trading/accounts/{id}/orders/{order_id}` | Get order by ID | | GET | `/v1/trading/accounts/{id}/orders:by_client_order_id?client_order_id=…` | Get by your client ID | | PATCH | `/v1/trading

What does the alpaca-broker-trading-orders skill do?

How do I install it?
Run `npx skills add alpacahq/alpaca-skills --skill trading-orders --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From alpacahq/alpaca-skills, a repository with 106 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
