## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.002 per call) distance calculation between two named locations without needing to set up a full mapping SDK. It requires no API key, making it ideal for lightweight agent workflows that need simple point-to-point distance lookups without routing, turn-by-turn directions, or map rendering.

## Known failure modes

- Invalid or unrecognized location strings — ambiguous place names may return incorrect results
- Missing 'to' or 'from' parameters result in a failed request
- Very specific addresses may not resolve correctly if the geocoding layer cannot identify them
- Network timeout or service unavailability returns an error response
