How this service works
Levenshtein edit distance and similarity for $0.001 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns the integer Levenshtein edit distance (minimum number of single-character insertions, deletions, or substitutions required to transform string A into string B) and a normalized similarity score (typically 0–1, where 1 is identical) between the two input strings.
Example use cases
Deduplicating customer name records
“I have two customer name entries — 'Jonathan Smith' and 'Jonathon Smyth' — can you compute their Levenshtein edit distance and similarity score so I can decide if they're the same person?”
Spell-check candidate scoring
“A user typed 'recieve' and the dictionary word is 'receive' — what's the Levenshtein distance and similarity between them so I can rank this as a spell-check suggestion?”
Product title near-duplicate detection
“Compare these two product titles for similarity: 'Apple iPhone 15 Pro 256GB' and 'Apple iPhone15 Pro, 256 GB' — give me the edit distance and similarity score.”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/levenshtein?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, affordable, single-call Levenshtein edit distance and similarity computation with micro-payment pricing ($0.001 USDC). Ideal for agents doing real-time fuzzy matching, deduplication, spell-check ranking, or record linkage without spinning up local NLP infrastructure.
Side effects
- Missing or empty input string — returns validation error
- Strings exceeding maximum allowed length — returns error or truncation
- Payment failure via x402 protocol — returns 402 Payment Required
- Network timeout for very long string pairs
