How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a numeric comparison score ('cmp') and a schema identifier ('schema': 'delx/util-cmp-str/v1'), indicating the degree of similarity or equality between the two input strings.
Example use cases
Duplicate record detection
“Compare these two company names — 'Acme Corporation' and 'ACME Corp.' — and tell me how similar they are so I can decide if they're the same entity.”
User input fuzzy matching
“The user typed 'Recieve payment' — compare it to 'Receive payment' and give me a score so I know if it's close enough to be a match.”
Password or code equality check
“Check if the string 'abc123XYZ' is identical or very close to 'ABC123xyz' and return a comparison score.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/cmp-str?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call string comparison without API key setup, especially in agent pipelines that already use USDC micropayments via x402 on Base or Solana. Ideal for low-volume, on-demand string matching where subscribing to a heavier NLP or fuzzy-match service is overkill.
Side effects
- Missing input field 'a' or 'b' returns an error
- Payment failure (insufficient USDC balance) returns 402
- Non-string inputs may cause validation errors
- Network timeout if the Base/Solana payment rails are congested
