How this service works
Produce a signature, idempotency, acknowledgement, and retry plan for webhooks. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authoriz…
Output
Returns a deterministic machine-readable JSON object containing a structured webhook delivery plan with recommendations for signature scheme, idempotency key strategy, acknowledgement expectations, and retry/backoff policy for the submitted event.
Example use cases
Preflight before enterprise webhook rollout
“Before we push our payment.completed webhook to production, generate a full delivery plan for this event — I need to know the recommended signature approach, how to handle idempotency, what acknowledgement the receiver should send, and the retry schedule: {"type":"payment.completed","paymentId":"pay_456","amount":500}.”
Security policy review for webhook signatures
“We're auditing our webhook security — can you produce a signature and idempotency plan for this user.updated event so I can verify our implementation matches best practices before the policy sign-off: {"type":"user.updated","userId":"usr_789","changedFields":["email","name"]}.”
Retry strategy design for unreliable receivers
“Our downstream integration sometimes goes down — give me a webhook delivery plan for this inventory.low event with a solid retry and acknowledgement strategy so we don't lose events: {"type":"inventory.low","productId":"prod_321","currentStock":5}.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/webhook-delivery-planWhen to prefer
Choose this endpoint when you need a deterministic, stateless preflight analysis of webhook delivery parameters — signature, idempotency, acknowledgement, and retry — before committing to a production integration. It is ideal for enterprise agent workflows that require machine-readable advisory output without any side effects, upstream data retention, or external service calls. Prefer it over manual policy design when you need consistent, reproducible recommendations at low cost ($0.003 USDC per call).
Side effects
- Missing or malformed event object returns a validation error
- Empty event payload may produce a minimal or incomplete plan
- Malformed JSON in the event field causes a parse error and rejection
- Network timeout returns no result; the call is stateless and safe to retry
