## 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-48d8ed3c -d '<json body>'
```

Example prompt: Fetch me a random fortune using the AgentCash fortune demo — go ahead and make the $0.001 USDC micropayment to get it.

## When to prefer this

Choose this endpoint when you want to demonstrate or test the x402 pay-per-call micropayment protocol with a lightweight, low-cost ($0.001 USDC) real API call. It is ideal for developers validating x402 payment flows, agent builders testing USDC micropayment integration, or anyone wanting a fun, minimal live demo of paid AI agent APIs. Not suitable for production fortune/quote needs at scale due to per-call cost.

## Known failure modes

- Insufficient USDC balance — payment fails and no fortune is returned
- Invalid or missing x402 payment header — 402 Payment Required response
- Network timeout reaching fortune.fulinlabs.com
- Vercel cold-start latency on first call
- Incorrect payment amount — payment rejected by facilitator

## How this service works

Random fortune — fixed price, x402 exact

## Output

A short fortune or wisdom statement returned as the response body after a successful $0.001 USDC micropayment via the x402 protocol. The agent receives the fortune text it can relay directly to the user.
