## 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-91ade22a -d '<json body>'
```

Example prompt: Can you check if hotel ID 'h_8821' on Roam has any rooms available for check-in June 20 and checkout June 23?

## When to prefer this

Use this endpoint when you already have a specific hotel ID and need to verify real-time room availability for a defined stay window. Ideal for AI agents that need pay-per-use, no-subscription accommodation lookup without setting up OAuth or API keys — just USDC micropayments via x402.

## Known failure modes

- Invalid or unknown hotel ID returns error or empty data
- Malformed date strings cause validation errors
- Missing required fields (id, checkin, checkout) cause 400-level errors
- Payment failure via x402 if insufficient USDC balance prevents request from being processed
- Dates in the past or reversed check-in/checkout may return errors or no results

## How this service works
