## 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 a402test-premium-data-endpoint-675f57e7
```

Example prompt: Can you fetch the premium data from the a402test endpoint? It costs $0.05 USDC per call and uses the x402 payment protocol.

## When to prefer this

Choose this endpoint when you need to test or demonstrate the x402 pay-per-call protocol with real USDC micropayments, or when integrating agentic payment-gated data retrieval into a workflow that uses Cloudflare Pages-hosted APIs. Best suited for developers validating x402 flows rather than production data consumers.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Invalid or missing x402 payment header results in access denied
- Network timeout if the Cloudflare Pages endpoint is unreachable
- Malformed payment token causes rejection before data is returned
