# x402.shizu.me Geospatial Computation

> x402.shizu.me Geospatial Computation is a paid API for AI agents from x402.shizu.me, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-16).

Computes the distance between two coordinates (in km and miles) or encodes a coordinate as a geohash string, via query parameters.

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 x402-shizu-me-geospatial-computation-620fafe4
```

Example prompt: What's the straight-line distance in km and miles between 40.7128,-74.0060 and 51.5074,-0.1278? Also give me the geohash for the New York coordinate at precision 6.

## When to prefer this

Use this endpoint when you need lightweight, on-demand geospatial computation — specifically great-circle distance between two coordinates or geohash encoding of a location — without setting up a full GIS library or geospatial database. It is ideal for agents that need quick distance checks or spatial indexing via geohash without self-hosting computation.

## Known failure modes

- Missing required query parameters returns an error
- Invalid or out-of-range latitude/longitude values cause a computation error
- Invalid precision value for geohash may return an error or use a default
- Payment not provided or insufficient USDC causes a 402 response
- Unsupported op value returns an error

## How this service works

Geospatial computation. op=distance (lat1,lon1,lat2,lon2 -> km and miles) or op=geohash (lat,lon,precision? -> geohash string). Inputs as query params.

## Output

For op=distance: returns the great-circle distance between two coordinate pairs in both kilometers and miles. For op=geohash: returns the geohash-encoded string for the given latitude/longitude at the specified precision level.
