| Tool | Description | Behaviour |
|---|---|---|
| call_endpoint | Executes an endpoint found via search_endpoints. Accepts a routeId and arguments. If payment is required, returns isError=true with payment details in structuredContent. In this case, the agent must sign the payment and retry the call with _meta["x402/payment"]. On success, returns the actual result of the endpoint. | Not declared |
| search_endpoints | Searches for paid API endpoints (x402) by task in natural language. Returns a structured plan (plan[]) with candidates. IMPORTANT: each candidate contains a routeId. To execute a found endpoint, pass this routeId to the call_endpoint tool. Do not attempt to call the URL directly — use call_endpoint. | Not declared |
