## How to buy

```text
PAID ($0.02/call): call_service({ id: "svc_83442a8e-d7d2-4aa9-8a50-5dcc7d5b272a", 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_83442a8e-d7d2-4aa9-8a50-5dcc7d5b272a", 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.
