Alpaca

Independent, unofficial connector for Alpaca. Not affiliated with, endorsed by, or sponsored by Alpaca. "Alpaca" is a trademark of its owner, used only to identify the service this connector works with.

Tools for trading on Alpaca against the Trading API: place and manage stock, crypto, and options orders; read account balances, positions, portfolio history, and activities; look up assets, market hours, and option contracts; and read watchlists. 25 scripts across account, orders, positions, assets, options, and watchlists. Trades run against Alpaca's paper (simulated) environment by default; live real-money trading requires an explicit opt-in (see Auth). Money and quantity values are returned as strings to preserve decimal precision — never coerce them to numbers. Order placement is async-confirmed: placeOrder acknowledges receipt with a status that can change server-side, so re-query getOrder before asserting a fill.

When to use this

• Inspect the account — read balances and buying power, list open positions and unrealized P&L, review portfolio history and account activities (fills, dividends, fees), or check whether the market is open.
• Place and manage orders — buy or sell stocks, crypto, or options (market/limit/stop/bracket/OCO/OTO/multi-leg); replace or cancel open orders; close or liquidate positions; exercise an options position.
• Look things up — resolve a symbol's tradability/shortability/fractionability, list assets or option contracts, and read watchlists.

Setup

This is an agentskills.io skill.

If the connector has not been installed as a skill yet, install it first with npx skills add zapier/connectors --skill alpaca (or your harness's own skill-install mechanism), then continue here. Installing the skill copies these files, not dependencies. Before running the CLI, a local MCP server, or zapier-sdk auth commands, run npm install --omit=dev here once. Importing the published package as a dependency in your own project instead? That npm install already resolves everything — see references/use-as-sdk.md.

The connector runs on Node.js 22.18+. Pick the reference that matches how you're running it, and load it before doing anything else:
