How this service works
ATMS x402 challenge — crawler / probe endpoint (always 402, no side effects)
Output
A 402 Payment Required HTTP response containing an x402 challenge payload — typically including payment details, USDC amount, and challenge metadata needed to complete the payment flow. No resource is created or modified.
Example use cases
Example prompt
“Ping the ATMS Treasury x402 challenge endpoint with a GET request to trigger a 402 payment-required response and show me the challenge payload it returns.”
Technical details
Endpoint
GEThttps://api.atms.nathanlidurin.com/x402/challengeWhen to prefer
Use this endpoint when you need to test or verify the x402 payment protocol challenge/response flow, confirm that a 402-gated endpoint is alive and returning valid challenge metadata, or crawl/probe x402-enabled APIs. This is not suitable for performing actual transactions or retrieving treasury data — it is purely a probe endpoint.
Side effects
- Always returns 402 by design — not an error, but the intended response
- Network timeout if the host is unreachable
- Unexpected 5xx if the server is misconfigured
- No useful data payload beyond the challenge structure
