# geo-geohash

> geo-geohash is a paid API for AI agents from x402.agentindex.world, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-29).

Encodes a latitude/longitude coordinate into a geohash string at a specified precision (1–12 characters).

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-geohash-82f0e7e1
```

Example prompt: Encode the coordinates 37.7749, -122.4194 (San Francisco) into a geohash string at precision 9.

## When to prefer this

Use this endpoint when you need a fast, cheap, pay-per-call geohash encoding with no API key setup — ideal for agents that occasionally need to encode coordinates into geohash strings without maintaining a subscription or library dependency. Prefer it over rolling your own geohash logic when operating in a serverless or agent environment.

## Known failure modes

- Latitude out of range (-90 to 90) returns a validation error
- Longitude out of range (-180 to 180) returns a validation error
- Precision outside 1–12 range returns a validation error
- Missing required lat or lon parameters returns a 422 or bad request error
- Payment failure results in 402 response before computation

## How this service works

Encode a lat/lon point into a geohash string (precision 1-12 characters).

## Output

Returns a geohash string of the requested precision (1–12 characters) that encodes the given latitude and longitude into a compact alphanumeric representation suitable for proximity indexing, clustering, or storage.
