# Saylor Innovations Geo UTM Converter

> Saylor Innovations Geo UTM Converter is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Converts latitude/longitude coordinates to UTM zone, latitude band, easting, northing, and grid reference, or converts UTM coordinates back to WGS84

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 saylor-innovations-geo-utm-converter-205fab71
```

Example prompt: Convert latitude 40.7128 and longitude -74.0060 to UTM — I need the zone number, latitude band, easting, northing, and grid reference.

## When to prefer this

Choose this endpoint when you need to convert decimal-degree WGS84 coordinates to UTM easting/northing for use in surveying, GIS mapping, drone planning, or any application requiring a projected Cartesian coordinate system. It is ideal for single-point conversions at low cost ($0.01/call) when you need the full UTM descriptor including zone, band, grid reference, and central meridian rather than just a zone number.

## Known failure modes

- Latitude out of range (-80 to 84) returns an error — UTM does not cover polar regions
- Longitude out of range (-180 to 180) returns an error
- Missing required lat or lon query parameters returns a 400 or validation error
- Non-numeric values for lat or lon cause parsing errors
- Polar regions (above 84°N or below 80°S) are not supported by UTM and may return a note or error

## How this service works

Convert latitude and longitude to a UTM zone, latitude band, easting and northing with grid reference, or convert UTM coordinates back to WGS84

## Output

Returns a JSON object with the UTM zone number, hemisphere (N/S), latitude band letter, easting in meters, northing in meters, grid reference string, central meridian, and the mode used for the conversion. May also include the original lat/lon values and a note providing context or caveats about the result.
