# Decimal Lat/Lon to MGRS Converter

> Decimal Lat/Lon to MGRS Converter is a paid API for AI agents from geospatial.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

Converts a decimal latitude/longitude coordinate to a Military Grid Reference System (MGRS) string on WGS84 with configurable precision.

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 decimal-lat-lon-to-mgrs-converter-e0212792 -d '<json body>'
```

Example prompt: Convert coordinates 34.0522° N, 118.2437° W to an MGRS string at full 5-digit precision.

## When to prefer this

Use this endpoint when you need to express a WGS84 decimal lat/lon as a standard MGRS grid reference — particularly for military, defence, search-and-rescue, or interoperability with mapping tools that require MGRS notation. Prefer this over UTM when the consumer expects the full MGRS zone-letter-square-easting-northing alphanumeric format. The configurable precision (1–5 digits per axis) makes it suitable for coarse area designation through to 1-metre field accuracy.

## Known failure modes

- Latitude out of range (< -90 or > 90) returns a validation error
- Longitude out of range (< -180 or > 180) returns a validation error
- Precision outside 1–5 returns a validation error
- Coordinates at the poles (lat ±90) may produce undefined MGRS output as MGRS is not defined at the poles
- Missing required lat or lon fields returns a 400 bad request
- Payment failure or insufficient USDC balance returns a 402 Payment Required

## How this service works

Convert decimal lat/lon to a Military Grid Reference System (MGRS) string on WGS84. Precision is the number of digits per axis (1–5; 5 = 1-metre resolution, default 5).

## Output

Returns an MGRS string (e.g. '11SPC8913697262') representing the input decimal coordinate on the WGS84 datum. Precision 5 (default) gives 1-metre resolution; lower values yield coarser grid cells (10 m, 100 m, 1 km, 10 km).
