How this service works
Similarity of two records from 0 to 1: Jaro-Winkler, token-sorted and Levenshtein ratios, and the strongest of the three as the headline score.
Output
Returns a JSON object containing three similarity scores (Jaro-Winkler ratio, token-sorted ratio, and Levenshtein ratio), each as a float between 0 and 1, plus a headline score representing the strongest of the three. Optionally includes a boolean match result if a threshold was supplied.
Example use cases
Customer record deduplication
“I have two customer entries — 'Acme Corp. LLC' and 'ACME Corporation' — can you check how similar they are using all three fuzzy match algorithms and tell me the strongest score so I can decide whether to merge them?”
Address typo detection
“Someone submitted '123 Elm Streeet, Springfield' but our database has '123 Elm Street, Springfield' — how similar are these two strings? Use a match threshold of 0.9 so I know if it's close enough to accept.”
Drug name variant matching
“Check if 'acetaminophen' and 'Acetaminofen' are similar enough to be the same drug — give me all three similarity scores and the headline match score.”

Endpoint
POSThttps://fittings.sh/v1/text/similarity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need multi-algorithm fuzzy string similarity in a single call — especially when Jaro-Winkler alone is insufficient for token-order-variant inputs (e.g. 'Smith, John' vs 'John Smith'), or when you want to pick the strongest of three algorithms without running them separately. Prefer over single-metric APIs when robustness across different string variation types matters.
Side effects
- Input string exceeds 512 characters — request rejected
- Missing required field 'a' or 'b' — validation error returned
- Threshold outside 0–1 range — bad request error
- Non-string input for 'a' or 'b' — type error
Input
