How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object conforming to schema 'delx/util-webhook-delivery-plan/v1', containing: max_attempts (integer), retry_strategy (e.g. exponential_full_jitter), require_signature (boolean), require_replay_window (boolean), idempotency_key_source (field path string), and acknowledge_within_seconds (integer).
Example use cases
Reliable webhook retry configuration
“I'm building a webhook handler and need to know the correct retry strategy, max attempts, and acknowledgment window for this incoming event object — can you get me the delivery plan?”
Idempotency key setup for event processing
“For this event, tell me what field I should use as the idempotency key and whether I need to enforce a replay window to avoid duplicate processing.”
Signature verification requirements for webhooks
“Does this webhook event require signature verification, and what are the full delivery settings I should enforce on my handler, including retry count and acknowledgment timeout?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/webhook-delivery-plan?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a standardized, opinionated webhook delivery configuration for a specific event, particularly when you want verifiable, pay-per-result infrastructure without signup overhead. Prefer this over hand-coding retry logic when you want consistent exponential backoff, idempotency, and signature verification settings derived from the event itself.
Side effects
- Missing or malformed event object in request body returns an error
- Payment not included or insufficient USDC payment via x402 returns 402 Payment Required
- Event structure not recognized may return a generic or default plan
- Network timeout or service unavailability returns 5xx error
