API.market

API.market is an API marketplace for developers and AI agents. Its proprietary hosted MCP gateway connects agents to API discovery and execution without requiring each API to be integrated separately.

MCP endpoint: https://api.market/api/mcp/gateway

Transport: Streamable HTTP. An API.market account and OAuth or API-key authentication are required.

The gateway exposes five tools: search_apis, get_api_tools, call_api, check_usage and manage_subscription. These support finding APIs, retrieving operation schemas, executing calls, checking usage and managing subscriptions. Catalog operations are distinct from the five exposed gateway tools.

Free tiers, paid plans and usage limits vary by API. Calls and subscription changes may incur charges. The hosted server implementation is proprietary. Setup documentation: https://api.market/mcp.
