Polygon.io
Polygon.io provides real-time and historical market data APIs for stocks, options, forex, and cryptocurrencies, enabling developers to build financial applications with ease.
This is a first-class FlyMyAI MCP. Agents discover it automatically via tool search and call the actions below on demand - you never wire it up by hand. See the Composio catalog for how discovery works.
Connect
Polygon.io authenticates with an API key. Generate the credential in your Polygon.io account, then paste it into FlyMyAI the first time an agent uses a Polygon.io action.
