## How to call it through Zero

```sh
zero fetch --capability us-cpi-bls-lookup-4c075e85
```

Example prompt: Can you get me the latest US CPI figure from the Bureau of Labor Statistics so I can see where inflation stands right now?

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to official US CPI data without managing API keys or subscriptions. Ideal for AI agents that require occasional inflation or price index lookups with micro-payments via USDC on Base, and where no persistent credentials are desired.

## Known failure modes

- Payment not included or invalid — returns 402 with payment instructions
- BLS data temporarily unavailable — upstream outage may cause empty or error response
- Invalid schema parameter — may return empty or malformed response
- Rate limit or worker error — returns 5xx
