## 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 datakoot-elevation-lookup-usgs-cef5e914 -d '<json body>'
```

Example prompt: What's the elevation at latitude 39.7392, longitude -104.9903 — give me both meters and feet using the USGS data?

## When to prefer this

Choose this endpoint when you need fast, authoritative ground elevation data for a specific US coordinate and want USGS-sourced results with both metric and imperial units in a single call. It is priced per successful call at $0.002 USDC via x402, making it cost-effective for spot lookups. Prefer alternatives if you need global (non-US) elevation coverage or bulk/batch elevation queries.

## Known failure modes

- Coordinates outside the US (non-US coordinates are not covered by USGS EPQS and will likely return an error or null elevation)
- Missing lat or lon parameter causes a validation error
- Invalid numeric format for lat/lon returns a bad request error
- USGS upstream service unavailability may cause a 500 or timeout
- Payment failure via x402 results in a 402 response and no data returned

## How this service works

48 live public-data tools (security, packages, SEC filings, economy, FX, weather, domains, Federal Register, Base) for AI agents. $0.002 USDC per call on Base via x402, charged only on success. The same tools are free for 100 calls/day via MCP at <server>.datakoot.com/mcp.

## Output

A JSON object containing the queried latitude and longitude, the elevation in meters (elevation_m) and feet (elevation_ft), and the data source attribution ('USGS EPQS (public domain)').
