## 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-hotel-vacancy-check-bbd94f2a -d '<json body>'
```

Example prompt: Check if hotel H-2847 has any rooms available from June 14 to June 18 using Roam's vacancy API.

## When to prefer this

Use this endpoint when you already have a specific hotel ID and need to verify room availability for defined travel dates before booking. It is ideal for AI agents orchestrating travel planning that need lightweight, pay-per-use hotel vacancy lookups without requiring API keys or subscriptions — just USDC via x402. Prefer this over broader hotel search APIs when you want a direct vacancy status check on a known property.

## Known failure modes

- Invalid or unknown hotel ID returns an error or empty data
- Malformed date strings may cause request failure
- Dates in the past or illogical date ranges (checkout before checkin) may return errors
- Hotel may return no vacancies (fully booked) with success true but empty data
- Network or server errors from the Vercel deployment may cause timeouts
- Insufficient USDC balance for x402 payment causes payment failure before request is processed

## How this service works

Accommodation search for AI agents. No auth, no subscriptions. Pay per request in USDC via x402.

## Output

Returns a JSON object with a success boolean and a data object containing vacancy details for the specified hotel and date range, such as available room types, quantities, or rate information.
