User-Agent API

healthy 3,768 Subscribers

A fast, fully-local User-Agent parser: detect the browser (name and version), rendering engine, operating system (name and a friendly version), device type (desktop, mobile, tablet, TV, wearable or bot), a mobile flag, and bot/crawler identity (Googlebot, Bingbot, social-preview bots, GPTBot/ClaudeBot, curl and more). Bot detection is included on every plan. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for analytics, ad-tech, fraud and bot filtering, personalization and access logs.

Astronomy API

A fast, fully-local astronomy and ephemeris engine: compute the equatorial (right-ascension/declination) and horizontal (azimuth/altitude) positions of the Sun, Moon and all planets for any observer and moment, get precise rise, set and transit (culmination) times for any body, read detailed lunar state (phase angle, named phase, illuminated fraction, apparent magnitude, geocentric distance, age since the last new moon and the dates of the next new/first-quarter/full/last-quarter moons), and list the exact equinoxes and solstices of any year. Every endpoint accepts input via the query string or the request body. Pure server-side computation (no third-party upstream), so responses are instant and always available. Ideal for weather and tide apps, astrophotography planners, calendars, solar/energy tools, Islamic and lunar calendars, and education.

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.

Bcrypt API

Hash and verify passwords with bcrypt, server-side. Generate a salted bcrypt hash at a cost factor you choose (4–14), check a plaintext password against an existing hash, or inspect a hash to read its bcrypt version, cost factor and salt. Fully compatible with bcrypt hashes from PHP ($2y$), Node, Python and others, so you can verify and migrate existing credentials. Pure server-side computation with no third-party upstream, so it is always available — and it offloads the deliberately CPU-intensive hashing work from your own servers. Ideal for adding password authentication, credential migration, auth tooling, testing and no-code backends.

PyPI Registry API

Python package data from PyPI as clean JSON. Look up any package’s latest metadata — version, summary, license, repository, author, keywords, required Python version, dependencies, supported Python versions and total release count — browse its full version history with release dates and yanked flags, or get the details and distribution files for one specific version. Sourced live from the public Python Package Index and returned through a fast, reliable API. Ideal for developer dashboards and tooling, package and dependency analytics, security and supply-chain checks, CI/CD and documentation sites.
