Top endpoints by trust score
- Jaccard index/v1/jaccardJaccard similarity index in [0,1] — the size of the intersection over the union of the two strings' character-bigram sets.→
- Hamming distance/v1/hammingHamming distance — the number of positions at which two EQUAL-LENGTH strings differ — plus a normalized similarity. Strings of unequal length are a clean 400.→
- Phonetic compare/v1/compareReport whether two tokens sound alike under a chosen algorithm (soundex, metaphone or double-metaphone; default double-metaphone). Returns each token's codes…→
- Jaro & Jaro-Winkler similarity/v1/jaroJaro similarity and the Jaro-Winkler variant (which boosts scores for a shared prefix), both in [0,1]. The prefix boost factor is configurable (default 0.1,…→
- Damerau-Levenshtein distance/v1/damerauDamerau-Levenshtein distance — like Levenshtein but also counts adjacent transpositions as a single edit — plus a normalized similarity in [0,1].→
