Overview
Build on Tradier
The Tradier API gives you direct access to a real brokerage for US stocks, ETFs, and options. You can pull real-time quotes, option chains with Greeks, and historical data. You can place everything from a simple equity order to a four-leg options spread or an OTOCO bracket, and preview every order before it goes out. Stream live quotes, trades, and account events over WebSocket or HTTP, or connect the Tradier MCP server to work with your account from Claude, ChatGPT, or Cursor. Every Tradier Brokerage account includes a paper trading sandbox, so you can build and test with no money at risk before you go live, and API access is included with your account at no extra charge.

I'm building for my own account
Use the API token from your account's API Settings page. No OAuth needed. Start in the sandbox, then switch the base URL and token to go live.
I'm building an app for other Tradier users
Public or distributed apps require Tradier Partner status and use the OAuth 2.0 Authorization Code flow. Contact sales@tradier.com to get started.
I want to use Tradier with AI
Point your coding assistant at llms.txt, or connect the Tradier MCP server to Claude, ChatGPT, Cursor, and other MCP clients to work with your account in natural language.
I'm an RIA or platform operator
The Advisor API adds account opening, ACH funding, documents, and multi-account data for registered advisors.

- Copy your tokens: Find your production and sandbox tokens on your API Settings page (web.tradier.com/user/api).
- Make a request: Get a quote:
curl -X GET "https://api.tradier.com/v1/markets/quotes?symbols=AAPL" \

Ready for more? Walk through placing an order, starting a market data stream, or pulling time and sales in Code Examples in each dedicated section of our documentation.
Before you build
Your token is full account access. Personal tokens don't expire until you regenerate them. Treat them like passwords and never commit them to a repository.
Check order status after placing. The place-order endpoint can return `200` even when a downstream system rejects the order. Confirm with Get Single Order and inspect the status.
Normalize arrays in JSON. A list with a single item can come back as a bare object instead of a one-element array.
Rate limits return `400`, not `429`. Detect the `Quota Violation` body and use the `X-Ratelimit-*` headers to throttle. For quotes that change constantly, stream instead of polling. → Rate Limits
Scope and coverage
- US equities, ETFs, and options only
- Market data is a consolidated feed.
- Level 1 (top-of-book) data only; no Level 2 / depth of book.
- Historical data isn't available for expired options.
- Pre- and post-market orders supported (07:00-09:24 and 16:00-19:55 ET)
- Without Partner status, API access is for personal use only; OAuth and token access scoping is only for partner applications.
- Any language that can make HTTPS requests works. Browser apps can call the REST APIs directly because CORS is supported (except OAuth exchanges).
