## 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 market-lnpay-ai-963a6fce -d '<json body>'
```

Example prompt: Call the LNPay Market protected resource endpoint using my x402 USDC wallet — it costs $0.01 per call and I need whatever data it returns for my agent workflow.

## When to prefer this

Choose this endpoint when your AI agent needs to access a pay-per-call protected resource on the LNPay agentic marketplace and supports the x402 HTTP payment protocol with USDC. Ideal for agents with built-in micropayment capabilities needing low-cost ($0.01) per-call access to gated resources without subscription overhead.

## Known failure modes

- Payment not included or malformed x402 header — returns 402 Payment Required
- Insufficient USDC balance — payment fails, resource not unlocked
- Invalid or expired payment token — authentication rejected
- Network timeout — no response from protected resource
- Rate limiting — too many requests in short window

## How this service works

Access to protected resource

## Output

Returns the response body of the protected resource after successful x402 micropayment verification; exact content depends on the underlying resource but typically includes structured data or a confirmation payload accessible only after the $0.01 USDC payment clears.

## Example request

 "query": "artificial intelligence",
 "method": "GET",
 "endpoint": "https://market.lnpay.ai/x402/agent"
