## 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 lineagelint-x402-webhook-security-pack-2e52b850
```

Example prompt: Can you purchase and download the x402 Provider Production Launch Kit from LineageLint so I have the webhook security pack ZIP with the SHA-256 checksum to verify it?

## When to prefer this

Use this endpoint when you need a pre-packaged, production-ready x402 webhook security implementation kit and are willing to pay $10 USDC per download. Prefer this over building from scratch when launching a new x402-compatible API provider and needing validated, versioned security tooling.

## Known failure modes

- Payment failure: insufficient USDC balance on Base mainnet results in 402 response
- Invalid or missing properties parameter may return an empty or malformed response
- Network timeout on large base64 payload delivery
- License mismatch: attempting to use for multiple providers violates single-provider license

## How this service works

An autonomous paid API accepting USDC on Base mainnet.
