## Run it

1. Find it: MCP search_apis, or GET https://apifare.com/v1/search?q=Image%20Comparator with Authorization: Bearer <token>. Take the result named "Image Comparator"; it carries a proxy_route.
2. Run it: MCP proxy_call with that proxy_route and the input JSON (apifare-mcp over stdio), or POST the proxy_route over HTTP with the input JSON as the body and the same Authorization header.
3. On HTTP 402, relay the body's human_readable field to your human verbatim, wait, then retry the same call. Every other error and its fix: https://apifare.com/errors.md
