## 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-mint-loyalty-tokens-fd09602f -d '<json body>'
```

Example prompt: Mint 500 loyalty tokens for wallet address 0xAbC123... on my 'MorningBloom Coffee' rewards program using Loyal Spark on Base — the customer just made a qualifying purchase.

## When to prefer this

Use this endpoint when you need to programmatically issue onchain ERC-20 loyalty tokens to a specific wallet on Base L2, especially in automated agent workflows triggered by customer actions like purchases or check-ins. Prefer this over off-chain point systems when verifiable, tradeable, or composable token rewards are required.

## Known failure modes

- Invalid or missing recipient wallet address returns a 400 error
- Insufficient funds or gas on Base L2 causes transaction failure
- Unauthorized request if API credentials are missing or invalid
- Token contract address not found or program not configured returns 404
- Network congestion on Base L2 may cause delayed confirmation or timeout
- Attempting to mint more tokens than the program cap allows returns a limit error

## How this service works

## Output

Returns a JSON response confirming the onchain mint, including the transaction hash on Base L2, the recipient wallet address, the number of ERC-20 loyalty tokens minted, and the updated token balance for that address.
