Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 google-maps-snaptoroads-ae099f4f
```

Example prompt: I have a series of raw GPS coordinates from a drive — 37.4229,−122.0840 then 37.4231,−122.0845 then 37.4235,−122.0850 — can you snap them to the nearest roads so the path lines up properly with the road network?

## When to prefer this

Use this endpoint when you have raw GPS traces from vehicles or devices and need to align them to the road network — ideal for route reconstruction, fleet tracking visualization, map-matching for navigation apps, or cleaning noisy GPS data. Prefer this over manual interpolation or other road-snapping services when accuracy against Google's road graph is required.

## Known failure modes

- Invalid or out-of-range coordinates return an error
- Too many input points exceeding API limit causes rejection
- Points in areas without road data may not snap accurately
- Missing path parameter returns 400 bad request
- Network timeout for large coordinate sets
- Coordinates far from any road may produce unexpected snapping results

## How this service works

Snap GPS coordinates to roads

## Output

Returns a list of snapped road points, each with corrected latitude/longitude coordinates aligned to the nearest road, along with optional place IDs for road segments and interpolated points that were added to fill gaps in the path.
