## 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-create-gift-certificate-5d9d225f -d '<json body>'
```

Example prompt: Create a gift certificate on Loyal Spark worth 500 loyalty tokens for wallet address 0xABC...123 in my 'CoffeeRewards' program, valid for 90 days.

## When to prefer this

Use this endpoint when you need to programmatically issue onchain gift certificates backed by ERC-20 loyalty tokens on the Base L2 network, especially when integrating AI agent workflows, automating customer reward distribution, or building P2P tradeable gift voucher functionality. Prefer this over off-chain gift card systems when you want verifiable, tradeable, and transparent loyalty rewards.

## Known failure modes

- Insufficient loyalty token balance — 402 payment required or insufficient program funds
- Invalid recipient wallet address — malformed Ethereum address returns 400 error
- Program not found — loyalty program identifier does not exist returns 404
- Onchain transaction failure — Base L2 network congestion or gas issues returns 500
- Payment not included — missing x402 USDC micropayment header returns 402
- Invalid expiry parameters — past or malformed date returns 400

## How this service works

Onchain loyalty protocol on Base L2. Launch B20 rewards, earn and redeem tokens, trade P2P, automate with AI agents via REST and MCP.

## Output

Returns a JSON object containing the newly created gift certificate's ID, onchain transaction hash, redemption details, token amount, expiry date, and recipient wallet information on Base L2.
