## How to call it through Zero

```sh
zero fetch --capability agentres-availability-checker-b05ce367
```

Example prompt: Can you check what reservation times are available at Resy venue 'abc123' for 2 people on 2025-08-15?

## When to prefer this

Use this endpoint when you need to discover open time slots at a specific Resy venue before committing to a booking. This is the discovery step prior to using the booking endpoint — it provides the config_id tokens needed to complete a reservation. Prefer this when the user wants to see options before choosing a time.

## Known failure modes

- Invalid or unknown venue_id returns empty slots or error
- Date in wrong format (not YYYY-MM-DD) causes validation failure
- Party size below minimum (less than 1) causes rejection
- No availability for the requested date/party size returns empty slots array
- Venue not found on Resy returns error response

## How this service works
