## 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 fuelsignal-live-energy-market-prices-6e592b0e
```

## When to prefer this

Choose FuelSignal when you need cheap, pollable, real-time energy commodity prices (WTI, Brent, diesel, gasoline, natural gas) and US gasoline stock data without setting up a full EIA or FRED API integration. At $0.01 per call it is ideal for high-frequency polling, agent workflows, and dashboards that need live energy market snapshots without the overhead of managing API keys for government data sources.

## Known failure modes

- Upstream EIA or FRED data delay may result in slightly stale values
- Rate limiting or payment failure for the $0.01 USDC x402 micropayment may return a 402 Payment Required error
- Invalid HTTP method (e.g. POST) will be rejected
- Network timeout if upstream data source is temporarily unavailable
