How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the computed Levenshtein edit distance (integer) between the two input strings — representing the minimum number of single-character insertions, deletions, or substitutions required to transform one string into the other.
Example use cases
Fuzzy product name deduplication
“I have two product names — 'Apple iPhone 14 Pro' and 'Apple iPhone14Pro' — can you compute the Levenshtein distance so I can decide if they're the same item?”
Spell-check candidate scoring
“I'm building a spell checker. Can you find the edit distance between the misspelled word 'recieve' and the correct word 'receive' so I can rank correction candidates?”
User input fuzzy matching
“A user typed 'Jonh Smith' in a form — how many character edits away is that from 'John Smith'? I want to decide whether to auto-correct it.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/levenshtein?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, verifiable, pay-per-call Levenshtein distance computation without signing up for a service or managing API keys — ideal for AI agents that need on-demand string similarity scoring with transparent USDC micropayment pricing via x402 on Base or Solana.
Side effects
- Missing 'input' or 'output' fields returns a 400 validation error
- Non-string body values may cause computation errors or unexpected results
- Payment failure via x402 (insufficient USDC balance or wrong chain) prevents execution
- Extremely long strings may time out or exceed processing limits
- Malformed JSON body returns a parsing error
