## 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 hookpulse-extra-endpoint-ed9dafad -d '<json body>'
```

Example prompt: Add a new extra endpoint on HookPulse pointing to my callback URL so I can start receiving event payloads from my webhook integration.

## When to prefer this

Choose this endpoint when you need to programmatically add or provision an additional webhook destination within the HookPulse ecosystem. It is best suited for dynamic integrations where the number or target of webhook endpoints changes at runtime, or for multi-tenant applications that need per-customer endpoint registration.

## Known failure modes

- Invalid or unreachable callback URL returns a 4xx validation error
- Duplicate endpoint registration may return a conflict error
- Insufficient prepaid credit (balance below $0.10 USDC) results in payment failure
- Malformed request body returns a 400 Bad Request
- Network timeout during endpoint provisioning returns a 5xx error
