## 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 loyal-spark-update-reward-status-ed9954a2 -d '<json body>'
```

Example prompt: On Loyal Spark, update the status of reward ID 'rwrd_abc123' in my 'CoffeeClub' loyalty program to 'redeemed' — it was just claimed by a customer.

## When to prefer this

Use this endpoint when you need to change the lifecycle state of an existing loyalty reward on the Loyal Spark protocol — for example marking it as redeemed, expired, or inactive after a customer claims it. Prefer this over creating a new reward when the reward already exists and only its status needs to change.

## Known failure modes

- Invalid or non-existent reward ID returns an error response
- Unauthorized access if caller lacks permission to modify the reward
- Invalid status value supplied results in validation error
- Network or Base L2 chain latency causes timeout
- Payment of $0.01 USDC not fulfilled causes x402 payment required error
- Reward already in terminal state (e.g. already redeemed) may reject update
