## 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 stayapi-availability-check-258ce38a -d '<json body>'
```

Example prompt: Check if hotel ID 'htl_manhattan_89' is available from June 14 to June 18 — I want to know if there are rooms open for those four nights.

## When to prefer this

Use this endpoint when you have a specific hotel ID and need to check its availability for given dates without requiring API keys or subscriptions — ideal for lightweight, pay-per-use agent workflows using x402 USDC micropayments.

## Known failure modes

- Invalid or unknown hotel ID returns error or empty data
- Malformed date strings cause request failure
- Missing required fields (id, checkin, checkout) result in validation error
- Payment failure via x402 protocol blocks the request
- Dates in the past or illogical date ranges may return no availability
- Service downtime on Vercel infrastructure causes 5xx errors
