## 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 pay-lnpay-ai-a9755413 -d '<json body>'
```

Example prompt: Access the protected resource at pay.lnpay.ai for me — go ahead and pay the $0.01 USDC micropayment via x402 to unlock and retrieve the content.

## When to prefer this

Choose this endpoint when you need to access a specific protected resource on pay.lnpay.ai that requires a $0.01 USDC micropayment via the x402 protocol. Prefer this over the 'safe data' sibling endpoint when the resource is known to be paywalled rather than publicly accessible.

## Known failure modes

- Payment insufficient or declined — resource not returned
- Invalid or expired payment token — 402 Payment Required returned
- Resource unavailable or server error — 5xx response
- Malformed request body — 400 Bad Request
- Payment provider unreachable — timeout or connection error

## How this service works

Access to protected resource

## Output

The agent receives the contents of the protected resource after the micropayment is processed. This is typically a data payload or API response that was previously gated behind the x402 paywall.

## Example request

```json
{
 "resource_url": "https://pay.lnpay.ai/res",
 "x402_enabled": true,
 "payment_amount": "0.01",
 "payment_currency": "USDC"
}
```
