API.market

Without a gateway, each outside API an agent uses usually needs its own key and setup. API.market's answer is a single MCP endpoint over Streamable HTTP. Once connected, an assistant can search the catalogue, look up an API's operations, make calls, check usage and manage subscriptions, which the submission describes as five gateway tools. The setup page has step-by-step instructions for Claude, ChatGPT, Codex, Cursor, VS Code and Claude Code, and you can copy every configuration without signing in.

The setup page counts 1,320+ APIs and 5,920+ tools in 44 categories. The homepage listings give a sense of the range and pricing, such as a text-guided image editing API at $0.027 per API unit, a subject relighting API at $0.043 per unit, video frame interpolation and dialogue text-to-speech. Other categories cover search and scraping, finance and crypto data, maps, e-commerce data, email and SMS, PDF tools, SEO data, and face recognition and ID verification. Each API has its own price, free tier and quota.

OAuth doesn't bypass anything. The setup page says API subscriptions and usage charges still apply and pay-as-you-go calls draw from your wallet, and it recommends keeping tool confirmations switched on and revoking access in Connected Apps when you no longer need it. On Claude's free plan, the connector uses your one custom connector slot. The privacy policy, last updated March 24, 2025, names Noveum.ai as the operator and says it doesn't sell personal information.
