## 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 geo-elevation-lookup-cf2bde98
```

Example prompt: What is the elevation in meters at latitude 40.7128, longitude -74.0060?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call elevation lookup for a specific lat/lon coordinate without needing to set up an account or API key. Ideal for AI agents performing one-off geospatial enrichment, route planning, or terrain analysis at $0.002 USDC per call via x402 on Base.

## Known failure modes

- Missing or invalid latitude/longitude parameters returns an error
- Coordinates over ocean or extreme poles may return zero or null elevation
- Service unavailability due to underlying DEM data source outage
- Malformed query parameters result in 400-level error

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

A JSON object containing the queried latitude, longitude, and the elevation at that point in meters (e.g. {"latitude": 40.7128, "longitude": -74.006, "elevation_m": 34.31}).
