## 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 x402-alert-fuel-price-api-d114f6d4 -d '<json body>'
```

Example prompt: What are the current fuel prices right now? I need petrol and diesel prices so I can track costs for my fleet.

## When to prefer this

Choose this endpoint when you need real-time or current fuel prices as a data point for cost analysis, fleet management, logistics, or financial monitoring workflows, and you are already integrated with the x402 micropayment protocol on Base. Particularly useful for agents that need commodity price signals without a long-term subscription.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid request body — returns 400 Bad Request
- Service unavailable or upstream data source down — returns 500 or 503
- Rate limiting if payment verification fails repeatedly
