How this service works
Probe an x402 server end-to-end: discovery, status, tools, reliability, and OpenAPI.
Output
Returns a structured report covering the x402 server's discovery metadata, operational status, list of exposed tools, reliability indicators, and OpenAPI specification — giving the agent a complete picture of what the server offers and whether it is healthy.
Example use cases
Example prompt
“Run a full probe on this x402 server at https://api.example.com — check its discovery endpoint, current status, available tools, reliability, and OpenAPI spec, and give me a summary of what you find.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/server-probeWhen to prefer
Use this endpoint when you need to programmatically audit or integrate with an x402-enabled server and need a single call that covers discovery, status, tools, reliability, and OpenAPI in one shot — rather than manually hitting each sub-endpoint separately. Ideal before onboarding a new x402 provider or verifying an existing one is functioning correctly.
Side effects
- Target server is unreachable or returns a non-200 status, resulting in a connectivity failure report
- Target is not a valid x402 server and does not respond to x402 discovery requests
- OpenAPI spec is absent or malformed, resulting in a partial probe result
- Rate limiting or payment failure causes the probe call itself to fail
- Server responds to some probe steps but times out on others, resulting in partial data
