Breweries API

Search, filter and locate breweries worldwide — a fast, clean wrapper over Open Brewery DB covering thousands of breweries across the US and beyond. Filter by city, state, country, name, postal code or brewery type (micro, nano, regional, brewpub, large, bar, contract and more), sort results nearest-first from any latitude/longitude, autocomplete brewery names for typeahead, pull random breweries, fetch a single brewery by id and read aggregate counts. Every endpoint accepts input via the query string or the request body and returns lean, predictable JSON with normalized address, coordinates, phone and website fields. Ideal for beer and travel apps, store locators, maps and directory features.

Geohash API

Work with geohashes through a fast, fully-local API. Encode a latitude/longitude pair into a geohash at any precision (1–12), decode a geohash back to its centre coordinates with the exact bounding box and error margins, list the eight neighbouring geohash cells (north, north-east, east and so on), or get the bounding box, centre and dimensions of a cell. Geohashes turn coordinates into short sortable strings that are perfect for spatial indexing, proximity grouping and map tiling. Pure server-side computation with no third-party upstream, so responses are instant and the service is always available. Ideal for geospatial indexing and search, proximity and nearby queries, map tiles and clustering, IoT and fleet tracking, and location bucketing in databases.
