How this service works
Computes the Levenshtein edit distance and a similarity percentage between two strings.
Output
Returns the integer Levenshtein edit distance (minimum number of single-character edits required to transform string a into string b) and a similarity percentage (0–100) indicating how alike the two strings are.
Example use cases
Deduplicating customer name records
“I have two customer name entries — 'Jonathan Smith' and 'Jonathon Smyth' — can you tell me how many edits apart they are and what their similarity score is so I can decide if they're duplicates?”
Spell-check candidate word scoring
“A user typed 'recieve' and I want to suggest 'receive' as a correction — can you compute the Levenshtein distance and similarity percentage between those two words to confirm it's a close enough match?”
Comparing product title variants
“I have two product titles: 'Wireless Bluetooth Headphones Pro' and 'Wireless Bluetoth Headphone Pro' — what's the edit distance and similarity score between them?”
Technical details
Endpoint
POSThttps://dt0ur.online/api/utility/diff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, character-level edit distance metric and a normalized similarity score between two strings. It is ideal for fuzzy matching, deduplication, spell-check scoring, or record linkage tasks where semantic meaning is less important than surface-level character similarity.
Side effects
- Missing one or both string inputs returns a validation error
- Extremely long strings may hit payload size limits
- Non-string types for fields a or b may return a type error
- Network timeout on high-latency connections
