## 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 roam-vacancy-check-50d138c5 -d '<json body>'
```

Example prompt: Can you check if hotel ID 'HTL-394820' has any rooms available from June 14 to June 19?

## When to prefer this

Use this endpoint when you have a specific hotel ID and need to check real-time room availability for a given date range without needing to set up an API key or subscription — especially useful in agentic workflows where pay-per-use via USDC x402 is acceptable

## Known failure modes

- Invalid or unknown hotel ID returns an error or empty data
- Malformed date strings cause request rejection
- Check-out date before check-in date results in an error
- Payment failure via x402 prevents the request from completing
- Hotel ID not found in the system returns a failed or empty response

## How this service works
