## Services

- [Text Diff (Word/Line)](https://www.zero.xyz/c/text-diff-word-line-39068653/llms.txt): $0.02/call via x402. Computes a diff of two short texts into equal, inserted, and deleted segments at word or line granularity, returning counts and a similarity ratio.
- [Text Similarity: N-gram Overlap (Dice & Jaccard)](https://www.zero.xyz/c/text-similarity-n-gram-overlap-dice-jaccard-0349b868/llms.txt): $0.02/call via x402. Computes Dice and Jaccard similarity scores using character or word n-gram overlap between two texts, in both set and multiset modes.
- [Text Similarity: Levenshtein & Damerau-Levenshtein Edit Distance](https://www.zero.xyz/c/text-similarity-levenshtein-damerau-levenshtein-edit-distance-b1fd920c/llms.txt): $0.02/call via x402. Computes Levenshtein and Damerau-Levenshtein (restricted OSA and unrestricted) edit distances between two texts, returning a normalized 0–1 similarity score.
- [Text Similarity Fuzzy Rank](https://www.zero.xyz/c/text-similarity-fuzzy-rank-09dc7e7d/llms.txt): $0.02/call via x402. Ranks up to 50 candidate strings against a query using Jaro-Winkler, Levenshtein, Dice, or cosine similarity, returning results sorted best-first with scores.
- [Text Similarity: Longest Common Subsequence & Substring (LCS)](https://www.zero.xyz/c/text-similarity-longest-common-subsequence-substring-lcs-94193c00/llms.txt): $0.02/call via x402. Computes the longest common subsequence and longest common substring between two texts, returning their lengths, the actual sequences, start positions, and a 0-to-1 similarity ratio.
- [Soundex Phonetic Code & Name Comparison](https://www.zero.xyz/c/soundex-phonetic-code-name-comparison-5c58d6da/llms.txt): $0.02/call via x402. Computes the American Soundex code for a name and optionally compares two names to determine whether they sound alike.
- [Text Similarity: Hamming Distance](https://www.zero.xyz/c/text-similarity-hamming-distance-08fca984/llms.txt): $0.02/call via x402. Computes the Hamming distance between two equal-length strings, returning the count and positions of differing characters.
- [Jaro / Jaro-Winkler String Similarity](https://www.zero.xyz/c/jaro-jaro-winkler-string-similarity-35f724fe/llms.txt): $0.02/call via x402. Computes Jaro and Jaro-Winkler similarity scores between two strings, including match count, transpositions, common prefix length, and a verdict summary.
- [Text Similarity – Cosine (Word-Count Vectors)](https://www.zero.xyz/c/text-similarity-cosine-word-count-vectors-4e66d4c7/llms.txt): $0.02/call via x402. Computes cosine similarity between two texts using word-count (bag-of-words) vectors, returning the similarity score, dot product, vector norms, and shared term count.
- [Original Metaphone Phonetic Key](https://www.zero.xyz/c/original-metaphone-phonetic-key-05afd941/llms.txt): $0.02/call via x402. Computes the Original Metaphone (Philips 1990) phonetic key for an English word, and optionally compares two words to determine if they share the same key.
