Tools 6 found in our last check

search_endpoints
FREE search for paid API endpoints (x402) by task. Pass either a natural-language query (the planner will split it) or pre-split queries[]. Returns a structured plan with up to `maxRoutesPerQuery` candidates per sub-query. No auth. Limits: burst 200/10s, total 1000/15min per IP;…
call_endpoint
Executes an endpoint found via search_endpoints. Pass `routeId` and `arguments` (keys = `parameters[].name` of that route, omit if the route has none). Flow: if you have a balance (see `top_up_balance`) and it covers the route price, pass `buyerID` next to `routeId` (not inside…
