## 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 saylor-innovations-bike-share-availability-c36f80d7
```

Example prompt: Can you show me the bike-share stations in Paris with free bikes and empty docks, sorted by distance from latitude 48.8566 and longitude 2.3522?

## When to prefer this

Choose this endpoint when you need real-time bike-share station availability (free bikes and empty docks) for any city globally, especially when you want results sorted by proximity to a specific location. It wraps the CityBikes aggregator, so it covers hundreds of cities and multiple bike-share networks without needing city-specific API keys. Prefer it over building direct CityBikes API calls when you want a simple single GET with optional geo-sorting built in.

## Known failure modes

- City not found or not served by CityBikes — returns empty or error response
- Invalid or missing city query parameter — likely returns 400 or error
- No stations found for the given city — empty stations array
- Optional lat/lon provided in wrong format — distance sorting may fail or be ignored
- CityBikes upstream outage — data may be stale or unavailable

## How this service works

Live bike-share availability for any city worldwide from CityBikes - free bikes and empty docks per station, sorted by distance from your lat/lon

## Output

A JSON object containing the matched bike-share network name, an array of stations with free bike counts and empty dock counts (optionally sorted by distance from the provided coordinates), summary totals, data source attribution, and a list of other matching networks in the city if multiple exist.
