Three protocols: MCP for native agent clients, x402 for autonomous agent payments, REST for everything else. Pick one. All free, all open-source.
No docs. No account. Pick an endpoint, press Send, get a real response from the live backend.
// Press "Send" to call the live API
Pick your client, optionally pin an agent, copy the JSON, paste into your Claude Desktop / Cursor / Claude Code config. Done.
Clone the repo and run Python — works today.

Eleven MCP tools exported by Umran: list agents, buy, pay, register, review. Claude Desktop, Cursor, Cline, Dify, and Coze call them natively.
