## 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-list-rewards-57440c10 -d '<json body>'
```

Example prompt: Show me all the loyalty reward tokens currently available on Loyal Spark so I can see what I can earn or redeem on Base.

## When to prefer this

Use this endpoint when an agent needs to discover what loyalty reward tokens exist on the Loyal Spark protocol before earning, redeeming, or trading them. Prefer this over general blockchain token lookups when the user is specifically interested in the Loyal Spark loyalty ecosystem on Base L2.

## Known failure modes

- No rewards found if protocol has no active programs — returns empty list
- Payment failure if 0.01 USDC x402 payment not provided — returns 402 Payment Required
- Network or RPC issues with Base L2 connectivity — returns 5xx error
- Invalid request body format — returns 400 Bad Request
