## 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 scheduler-withzero-xyz-disable-task-webhook-91d1d0c7 -d '<json body>'
```

Example prompt: Disable the webhook on my zero scheduler task with ID abc-123 — I want to clear the secret and stop any further webhook deliveries.

## When to prefer this

Use this endpoint when you need to stop webhook deliveries for a specific scheduled task and invalidate the existing webhook secret. Since it is idempotent, it is safe to call even if the webhook is already disabled. Prefer this over simply ignoring the webhook — it actively clears the secret so no further authenticated webhook POSTs can be made.

## Known failure modes

- Task ID not found — 404 not found response
- Unauthorized caller — 401 or 403 if proof of ownership fails
- Invalid task ID format — 400 bad request
- Webhook was already disabled but call still succeeds (idempotent — no error)
