OpenAPI Specification

openapi: 3.2.0
info:
  title: Clearhouse Index API
  description: 'One search across every agent registry. Clearhouse crawls the official MCP registry, Glama, Smithery and the x402 Bazaar every six hours, deduplicates across them, and exposes one index.


    No key is required. Responses are JSON. The same index is available to agents natively as an MCP server at `https://mcp.clearhouse.sh/mcp`.


    Receipts issued by Clearhouse verify against the key published at `/.well-known/clearhouse-keys.json`.'
