API Clearinghouse provides two integration paths. Choose the one that matches your setup.
Direct HTTP access to all APIs from any language or tool. Authenticate with an API key, call https://api.apiclearinghouse.com/v1/call/..., and receive normalized JSON. Includes OpenAPI spec for SDK generation and Postman import.
Connect Claude Desktop, Cursor, or any MCP-compatible AI agent to all APIs as native tools in one config line. Trial mode requires no API key — discover and demo live APIs directly from inside your agent conversation.
