## How to buy

```text
PAID ($0.005/call): call_service({ id: "svc_c0d8a5f6-b4ec-44d8-b57b-aee9b6db9ac2", args }) — the 402 lists ONE x402 payment = the FULL price straight to the seller (FiatDock takes 0% of this listing's calls right now); the fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays it automatically. This remote /mcp returns the 402 challenge. You are charged only if the seller actually answers. To learn what to put in arguments, call get_service({ id: "svc_c0d8a5f6-b4ec-44d8-b57b-aee9b6db9ac2", includeSchemas: true }) first — it returns toolSchemas (argument names and types). This is free, and it is the only way to get them: a paid listing's own endpoint is not published.
