Maze API

healthy 4,240 Subscribers

Generate and solve mazes — entirely locally and reproducibly. The generate endpoint builds a perfect maze (exactly one path between any two cells, no loops) of the width and height you choose, using either a recursive-backtracker algorithm (long, winding corridors) or Prim's algorithm (more branching, shorter dead-ends), and returns it as ready-to-print ASCII art plus a compact per-cell wall-bitmask grid, with the start marked top-left and the exit bottom-right. Every maze is fully reproducible: pass a seed and you always get exactly the same maze on any machine, and the seed is returned when you omit it so you can recreate it later. The solve endpoint re-creates the maze from the same seed, width, height and algorithm and returns the shortest path from start to finish, both as an ordered list of cells and drawn onto the maze. Everything is computed locally and deterministically, so it is instant and private. Ideal for games and puzzles, procedural level generation, teaching algorithms and graph search, printable activity sheets, and creative coding. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints.

Avatar API

Generate deterministic avatars and identicons from any seed — the same seed always renders the exact same avatar, so user IDs, usernames or emails map to stable, unique profile pictures with no storage. 30 art styles (bottts robots, pixel-art, avataaars, identicon, lorelei, notionists, fun-emoji, shapes, rings and more), returned as ready-to-use SVG markup or a base64 PNG data-URI, with options for size, corner radius, background colour and flip. Backed by DiceBear. Ideal for default user avatars, comment/forum placeholders, dashboards, game characters, test fixtures and any UI that needs an instant, reproducible profile image.

Sudoku API

Generate, solve and validate Sudoku puzzles through a fast, fully-local API. Create fresh puzzles at four difficulty levels (easy, medium, hard, expert), each guaranteed to have exactly one solution, returned as both an 81-character string and a 9x9 grid alongside the full solution. Solve any valid puzzle with a backtracking engine that also reports whether the solution is unique, and validate a grid to detect rule conflicts and completeness. Inputs accept an 81-character string (0 or . for blanks) or a 9x9 array, by GET or JSON POST. Pure server-side compute with no third-party upstream, so responses are instant and the service is always available. Ideal for puzzle apps and games, newspapers and printables, tutors and training-data generation.

Password API

A fast, fully-local password toolkit: generate cryptographically-secure random passwords (configurable length, character classes and exclude-similar), estimate password strength (entropy bits, a 0-4 score, character-class breakdown, common-password detection, an offline crack-time estimate and actionable feedback), and create memorable diceware-style passphrases. Built on Node crypto, no third-party upstream, and inputs are never logged — so responses are instant, private and always available. Ideal for signup and account flows, admin tools, password managers and security features.
