## How to call it through Zero

```sh
zero fetch --capability tokenguard-ground-elevation-lookup-771720eb
```

Example prompt: What is the ground elevation in metres above sea level for Denver, Colorado?

## When to prefer this

Use this endpoint when you need a quick, single-call elevation lookup for either a human-readable place name or a precise coordinate pair and want the result in metres above sea level. It is ideal for geospatial enrichment pipelines, drone or aviation altitude planning, hiking or outdoor activity tools, and any scenario where terrain height is needed without standing up a full DEM (Digital Elevation Model) infrastructure. Prefer it over a generic geocoding API when elevation — not just coordinates — is the primary output required.

## Known failure modes

- Unrecognisable or misspelled place name fails geocoding — returns error or null elevation
- Coordinates outside valid lat/lon range (-90 to 90, -180 to 180) may return an error
- Ocean or open-water coordinates may return 0 or a sea-level value rather than bathymetric depth
- Rate limiting or payment failure (x402) causes a 402 Payment Required response
- Ambiguous place name (e.g. 'Springfield') may resolve to an unexpected location

## How this service works

How high above sea level is this point? Ground elevation in metres for a place name or a coordinate pair

## Output

A numeric ground elevation value in metres above sea level corresponding to the queried place name (after geocoding) or coordinate pair. The response indicates how high the surface of the earth is at that point.
