## 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 stabletravel-by-square-a093e7a5
```

Example prompt: What tours and activities are available in central Paris? Search within the bounding box from latitude 48.90 north to 48.82 south and longitude 2.25 west to 2.42 east, and return up to 30 results.

## When to prefer this

Choose this endpoint when you need to discover tours and activities within a precise geographic region defined by coordinate boundaries — ideal for map-based UIs, 'things to do near me' features, or when you have bounding box coordinates from a map viewport. Prefer this over city-name or keyword search when spatial precision matters or when integrating with geospatial tools.

## Known failure modes

- Missing required boundary parameters (north, west, south, east) returns a 400 error
- Invalid or out-of-range latitude/longitude values cause a validation error
- Very large geographic areas may return truncated results capped at max
- No activities found in a remote or unsupported region returns an empty data array
- Upstream Amadeus API unavailability causes a 502 or 503 error
