## 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-gift-certificates-f1d603c0 -d '<json body>'
```

Example prompt: Show me all the gift certificates currently available to redeem on Loyal Spark for my wallet — I want to see what I can use my loyalty tokens on.

## When to prefer this

Use this endpoint when an AI agent needs to discover or display available gift certificates within the Loyal Spark ecosystem, specifically when operating within a Base L2 onchain loyalty context. Prefer this over generic reward lookup endpoints when the user is dealing with ERC-20-based loyalty tokens on Loyal Spark and wants to see redeemable gift certificate options.

## Known failure modes

- Invalid or missing authentication/wallet credentials returns an error
- No gift certificates available returns an empty list
- Network or Base L2 RPC connectivity issues cause timeout
- Malformed request body returns 400-level error
- Payment of $0.01 USDC not fulfilled causes x402 payment required error
