## 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-x402-transfer-gateway-ca1ff100 -d '<json body>'
```

Example prompt: Use Loyal Spark's onchain gateway to transfer loyalty reward tokens to customer wallet 0xABC...123 for their recent purchase — POST the transfer with JSON body to the x402 gateway on Base Network.

## When to prefer this

Use this endpoint when you need to programmatically execute loyalty token transfers or reward distributions on the Loyal Spark platform via the x402 micropayment protocol on Base Network. Prefer this over generic blockchain transfer endpoints when the goal is specifically issuing, redeeming, or routing branded ERC-20 loyalty rewards through an AI-agent-compatible gateway with built-in x402 payment handling.

## Known failure modes

- Invalid or missing required fields (type, method, bodyType, body) returns 400 validation error
- Insufficient x402 payment (underpayment of $0.005 USDC) results in 402 Payment Required
- Invalid HTTP method (not POST/PUT/PATCH) returns schema validation error
- Malformed JSON body causes parsing failure
- Network or Base chain congestion causing delayed transaction confirmation
- Unauthorized wallet or missing authentication headers returning 401/403
