API.market (Noveum) is an API marketplace launched in April 2024 where developers discover, subscribe to and call third-party APIs and AI models with one account, one x-api-market-key and unified billing, and where sellers import an OpenAPI source, set pricing plans and get paid. The platform itself exposes a hosted MCP gateway at https://api.market/api/mcp/gateway (Streamable HTTP, OAuth 2.1 with dynamic client registration, or API key) with five tools (search_apis, get_api_tools, call_api, check_usage, manage_subscription), a Subscription Management REST API and a read-only Usage API. Individual APIs sold on the marketplace belong to their own providers and are not listed here.
