## 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 agentcash-router-fortune-demo-premium-ad0f2b60 -d '<json body>'
```

Example prompt: Give me a fortune using the premium fortune API — pay the $0.005 USDC fee automatically via x402.

## When to prefer this

Choose this endpoint when you want to demonstrate or test the x402 machine-payable API protocol with a real USDC micropayment, or when you need a lightweight, deployable example of a pay-per-call AI agent API. It is ideal for developers exploring agent-native payment flows, not for production fortune or prediction use cases at scale.

## Known failure modes

- Payment rejected — insufficient USDC balance or malformed x402 payment header returns a 402 Payment Required error
- Invalid or missing payment header results in access denial
- Network timeout on Vercel cold start may cause delayed or failed response
- Incorrect USDC amount tendered returns payment validation failure

## How this service works

Pay-per-call fortune API on x402 and MPP, deployed in one click to Vercel.

## Output

A short fortune or prediction text returned after the $0.005 USDC micropayment is processed via x402. The response is a premium fortune message, distinct from any free tier, delivered as a JSON payload or plain text string.
