## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-webhook-delivery-plan-54b6c3ad -d '<json body>'
```

Example prompt: Give me a webhook delivery plan for this event so I know how many retry attempts to make, what retry strategy to use, and how quickly I need to acknowledge it.

## When to prefer this

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.

## Known failure modes

- 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

## How this service works
