What can you do with Marketstack on Tray.ai?
Marketstack is a stock market data API from APILayer that returns end-of-day, intraday and historical prices for tens of thousands of tickers worldwide. Tray.ai connects to Marketstack through the HTTP Connector, so your workflows can call the Marketstack API alongside the rest of your stack.
- Get end-of-day prices each evening and load them into your data warehouse.
- Get ticker dividends and share upcoming payouts with your finance team.
- Get latest intraday prices to refresh the market panel on your internal dashboard.

Set it up
Connect Marketstack to Tray.ai
Each step uses Marketstack's own API details, from its documentation.
Step 1
Save Marketstack's API key
Save the key as a Tray.ai authentication and add it to the query string from $.auth, so it never sits in the workflow itself.
Step 2
Point the HTTP Client at the API
Add an HTTP Client step and use https://api.marketstack.com/v2 as the base URL. Or paste a cURL example from Marketstack's API docs, and Tray.ai fills in the method, URL, and headers.
Step 3
Start with “Get end-of-day prices”
It's one of 13 documented actions, under End-of-day prices. The response comes back as data the next step can map into your other apps.
Step 4
Hand it to an AI agent
Wrap “Get latest end-of-day prices” and “Get intraday prices” in workflows, and Tray.ai's Agent Gateway for MCP publishes them as governed tools Claude and other AI agents can call.
