String Similarity API
A fast, fully-local string similarity and fuzzy-matching toolkit: edit distances (Levenshtein, Damerau-Levenshtein, Hamming), normalized 0-1 similarity scores (Levenshtein ratio, Jaro, Jaro-Winkler, Dice and Jaccard), Soundex phonetic codes, and best-match ranking of a query against a candidate list. 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 record matching and deduplication, search and autocomplete, spell-checking, data cleaning and entity resolution.
