How this service works
Encode a WGS-84 latitude and longitude to a geohash at a chosen precision, or decode a geohash back to its bounding box, centre point and error bounds in metres. Encoding also returns the eight neighbouring cells, which is what a caller needs to do proximity search over a geohash-indexed store without a spatial database.
Output
For encode: the geohash string at the requested precision, plus an object with the 8 cardinal and diagonal neighbour geohash strings. For decode: the bounding box (min/max lat and lon), the centre lat/lon, precision length, and positional error in metres for both axes. All responses include a request ID, timestamp, determinism flag, and price metadata.
Example use cases
Proximity search without spatial database
“I have a store of POIs indexed by geohash. Convert latitude 40.7484 and longitude -73.9967 to a precision-7 geohash and give me all 8 neighbouring cells so I can query the surrounding tiles.”
Decoding a stored geohash to coordinates
“I've got the geohash 'u173zq5mt' stored in my database — decode it and tell me the centre lat/lon, bounding box corners, and how many metres of error to expect.”
Building a geofence at coarse granularity
“Encode coordinates 35.6895 latitude and 139.6917 longitude as a geohash at precision 5 so I can cluster nearby locations into neighbourhood-level buckets.”
Technical details
Endpoint
GEThttps://api.duoleads.com/v1/geo/geohash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, serverless geohash encoding or decoding without standing up a spatial database or importing a geohash library. It is especially useful when you need the 8 neighbours of a cell in the same call, which is the standard pattern for radius queries over geohash-indexed data. Prefer it over full spatial databases when the only operation needed is index-key computation at a known precision.
Side effects
- Missing required lat/lon when op=encode returns a validation error
- Missing geohash parameter when op=decode returns a validation error
- Latitude out of -90 to 90 range causes a bad-request error
- Longitude out of -180 to 180 range causes a bad-request error
- Precision outside 1-12 range causes a validation error
- Geohash containing invalid characters (not in base-32 alphabet) returns a pattern-mismatch error
- Payment failure (x402) if USDC funds are insufficient or wallet is not configured
