## Run it

1. Find it: MCP search_apis, or GET https://apifare.com/v1/search?q=Japan%20bitFlyer%20%26%20Coincheck%20Crypto%20%E2%80%94%20%E6%9A%97%E5%8F%B7%E8%B3%87%E7%94%A3%20API with Authorization: Bearer <token>. Take the result named "Japan bitFlyer & Coincheck Crypto — 暗号資産 API"; 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
