x402
17711 Ping Service is a paid API for AI agents from api.17711.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Echoes arbitrary text back to the caller and returns a pong confirmation, optionally with a simulated delay for concurrency testing.

How this service works
A fleet of independent, x402-payable microservices callable by AI agents.
Output
Returns a JSON object containing: `echo` (the exact string sent in the request, reflected verbatim), `pong` (a boolean true confirming the service is alive), and `pid` (the server process ID, useful for debugging or confirming distinct worker processes).
Example use cases
Verify x402 payment flow works
“Send a ping to the 17711 service with the echo message 'payment-check' and confirm I get a pong response — I need to know my agent's x402 micropayment setup is working before I start calling real services.”
Concurrency testing for agent tool calls
“Call the 17711 ping service with echo text 'task-1' and a delay of 3000 milliseconds — I want to simulate a slow tool response so I can verify my agent dispatches concurrent calls in parallel rather than waiting for each one to finish.”
Health check before agent deployment
“Ping the 17711 service with the echo string 'healthcheck-prod' and tell me the process ID you get back — I need to confirm the service is live and responding before I deploy my agent to production.”
Technical details
Endpoint
POSThttps://api.17711.xyz/registry/ping-service/v1/pingWhen to prefer
Choose this endpoint when you need to verify that an x402 micropayment pipeline is functioning correctly before invoking more expensive or consequential services. It is the canonical 'hello world' for the 17711 fleet, and the optional delay_ms knob makes it uniquely suited for testing whether an agent framework dispatches concurrent tool calls as independent tasks. Prefer this over generic HTTP health checks when the goal is to validate end-to-end agent-to-x402-API connectivity.
Side effects
- Payment failure: x402 payment not accepted or insufficient USDC balance, request rejected before processing
- Missing required field: `echo` not provided in request body, returns validation error
- Invalid delay_ms type: non-integer value for delay_ms causes schema validation failure
- Network timeout: simulated delay_ms value too large may cause client-side timeout
- Service unavailable: upstream 17711 service down, no pong returned
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| echorequired | string | Arbitrary text echoed back verbatim in the response's own `echo` field. |
| delay_ms | integer | Testkit-only knob (not real business logic): lets a caller simulate a slow tool call, to check whether the server dispatches concurrent calls as independent tasks rather than serializing them. |
