#words

A complete toolkit for Wordle-style word games: score a guess against a hidden answer and get the exact green/yellow/grey feedback pattern (with correct duplicate-letter handling), validate any word against the official dictionary, solve a puzzle from the clues collected so far (returns the remaining consistent answers and a suggested next guess that best narrows them down), pull a random answer word, and fetch the deterministic daily word for any date with its puzzle number. Built on the official answer list (2,315 words) and the full set of ~13,000 accepted guesses. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side compute (no third-party upstream), so responses are instant and always available. Ideal for word-game backends, solvers and assistants, bots and educational apps.

Every endpoint accepts input via the query string or the request body. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for invoicing and billing, localization, education and developer formatting tooling.
