## 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 arcgate-agent-webhook-channel-create-ed63384d -d '<json body>'
```

Example prompt: Set up a webhook channel for my agent at address 0xAbC123... so that it receives event notifications at https://myapp.example.com/agent-hooks — I want the agent to be notified automatically whenever relevant events come in.

## When to prefer this

Choose this endpoint when you need your agent to passively receive event-driven HTTP push notifications rather than polling. It is the right choice if your agent has an on-chain address on Arcgate and you want to wire up a callback URL to trigger downstream workflows automatically. Prefer this over watch-based or Telegram channels when your backend already exposes an HTTP endpoint and you want a standard webhook integration pattern.

## Known failure modes

- Invalid or malformed agent address returns a 400 error
- Malformed or unreachable webhook URL may be rejected
- Duplicate webhook channel for the same address may return a conflict error
- Insufficient payment (x402) causes a 402 Payment Required response
- Authentication or authorization failure for the agent address

## Output

Returns details of the newly created webhook channel, including a channel ID and confirmation that the callback URL has been registered to the specified agent address for receiving event notifications.
