Elevation Above Sea Level for Coordinates (Open Topo Data)

opentopodata/elevation-lookup

Elevation in metres above sea level for up to 100 latitude/longitude points in one call, from a chosen public elevation dataset: srtm90m (default), srtm30m, aster30m, ned10m (United States only), eudem25m (Europe), etopo1 or gebco2020 (global, ocean depths are negative). Optional interpolation: nearest (default), bilinear or cubic. Points are given as `lat,lng` pairs separated by `|`. A point outside a dataset's coverage returns elevation null, not an error. Results come back in input order, each with the dataset name. Data from the Open Topo Data public API as served by Eden Engine, not an official Open Topo Data product.

Price

$0.0026 per call

You pay the price shown. If a call turns out to cost more than its quote, you pay the actual price, capped at twice the quote. No monthly minimum. Top-ups start at $0.50.

Data source

Open Topo Data

Elevation values from the Open Topo Data public API (opentopodata.org), read from public datasets named in each result: SRTM (NASA/USGS), ASTER GDEM (NASA/METI), NED (USGS), EU-DEM (Copernicus), ETOPO1 (NOAA) and the GEBCO 2020 grid. Credit the dataset named in the result. Passed through unmodified. Served by Eden Engine; not an official Open Topo Data product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "opentopodata/elevation-lookup" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "opentopodata/elevation-lookup" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "opentopodata/elevation-lookup", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "opentopodata/elevation-lookup", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
