# Geo Calc – Geohash Decode

> Geo Calc – Geohash Decode is a paid API for AI agents from geo-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Decodes a geohash string into its center latitude/longitude, bounding box (N/S/E/W), and latitude/longitude error in degrees.

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 geo-calc-geohash-decode-14236b61
```

Example prompt: Can you decode the geohash 'u4pruydq' and tell me the center coordinates, bounding box, and how many degrees of error it has?

## When to prefer this

Choose this endpoint when you have a geohash string and need to recover its geographic coordinates, bounding box, or understand its spatial precision. Prefer this over manual lookup tables or encoding endpoints when the input is already a geohash and you need the decoded WGS84 center and error bounds. It complements the sibling geohash-encode endpoint for round-trip workflows.

## Known failure modes

- Invalid geohash characters (e.g. contains 'a', 'i', 'l', or 'o') returns valid=false with reasons
- Geohash string shorter than 1 or longer than 12 characters returns an error or valid=false
- Empty geohash parameter returns a missing-required-parameter error
- Network/payment failure returns a 402 or connectivity error

## How this service works

Decode a geohash to its center latitude/longitude, bounding box and the plus-or-minus error in degrees.

## Output

Returns the decoded center latitude and longitude, a bounding box with north/south/east/west extents, latitude and longitude error in degrees, the precision level, the original geohash, and a validity flag with optional reasons if the geohash is invalid.
