# Open-Meteo Terrain Elevation API

> Open-Meteo Terrain Elevation API is a paid API for AI agents from AIsa MPP Data APIs at api.aisa.one, paid per call via MPP, $0.0001/call, status unknown (last checked 2026-10-18).

Returns terrain elevation (DEM) in meters for one or more WGS84 coordinate pairs.

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 aisa-mpp-data-apis-open-meteo-terrain-elevation-api-df9f5539
```

Example prompt: What's the terrain elevation at latitude 52.52, longitude 13.41 (Berlin)?

## When to prefer this

Choose this endpoint when you need fast, pay-per-request terrain elevation data for one or up to 100 coordinate pairs without managing your own DEM tiles or Open-Meteo API keys. Ideal for agents that need to enrich location data with altitude, perform route analysis, or assess terrain profiles programmatically.

## Known failure modes

- Missing latitude or longitude parameter returns a 400/422 validation error
- Malformed coordinate values (non-numeric or out-of-range) may return an error or NaN
- Mismatched number of latitudes and longitudes in batch mode causes an error
- Coordinates over ocean or unmapped terrain may return 0 or null elevation
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

Terrain elevation (DEM) by coordinates.

## Output

Returns a JSON object containing elevation values in meters above sea level for each coordinate pair provided. For batch requests, values are aligned positionally with the input latitude/longitude lists. Data is sourced from a digital elevation model (DEM).
