## 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 cron402-top-up-10-credits-3f774501 -d '<json body>'
```

Example prompt: My cron402 job with ID 3f2504e0-4f89-11d3-9a0c-0305e82c3301 ran out of credits and stopped firing — add 10 more run credits to it so it starts working again.

## When to prefer this

Choose this endpoint when you need a small, cost-effective top-up of exactly 10 credits ($0.08) for a cron job — ideal for testing, low-frequency jobs, or fine-grained credit management. For bulk replenishment, prefer the 100-credit ($0.80) top-up endpoint instead.

## Known failure modes

- Job ID not found — returns 404 if the UUID does not correspond to an existing job
- Invalid UUID format — returns 400 if jobId is malformed
- Payment failure — returns 402 if USDC payment of $0.08 cannot be processed
- Job already has maximum credits — may return an error or cap the balance
- Service unavailable — returns 5xx if the Cloudflare Worker is down
