How this service works
Deterministic validation of A2A Agent Card JSON before agent interaction. Paid per request through x402 v2 on Base Mainnet.
Output
Returns a deterministic validation result indicating whether the submitted A2A Agent Card JSON is well-formed and compliant, along with specific error details or field-level issues if validation fails.
Example use cases
Pre-deployment agent card check
“I'm about to deploy a new A2A agent and I want to validate my agent card JSON first — it's a POST with a JSON body. Can you run a preflight check and tell me if everything looks correct before I go live?”
Debugging malformed agent card
“My agent-to-agent call keeps failing and I think my agent card might be malformed. Can you run a preflight validation on this JSON body as a POST request and tell me exactly what's wrong with it?”
CI pipeline agent card validation
“As part of our build process, validate this A2A agent card JSON — submitted as a POST with a JSON body — and fail the pipeline if the preflight check returns any errors.”
Technical details
Endpoint
POSThttps://preflight.pounga.com/v1/preflight/a2aWhen to prefer
Choose this endpoint when you need deterministic, structural validation of an A2A Agent Card JSON payload before initiating an agent-to-agent interaction — especially useful in CI/CD pipelines, pre-deployment checks, or debugging sessions. Prefer this over runtime trial-and-error when correctness of the agent card is critical and you want to avoid wasted live calls or costly downstream failures.
Side effects
- Invalid or missing required 'input' object returns a schema validation error
- Unsupported HTTP method (anything other than POST, PUT, PATCH) is rejected
- Malformed JSON body causes parse failure
- Payment not fulfilled via x402 v2 on Base Mainnet results in 402 Payment Required
- Unsupported bodyType enum value triggers input rejection
- Network timeout or service unavailability returns 5xx error
