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 Soundex code (e.g. 'H425'), the uppercased input text, and a schema identifier ('delx/soundex/v1') confirming the encoding algorithm used.
Example use cases
Deduplicating customer name records
“I have a customer database with lots of spelling variations of the same name — can you get the Soundex code for 'Thompson' so I can group it with phonetically similar entries like 'Thomson' and 'Thompsen'?”
Fuzzy name search in a lookup table
“I'm searching a registry for the surname 'Knudsen' — can you give me its Soundex code so I can find all phonetically equivalent last names stored in the index?”
Genealogy research name matching
“Can you compute the Soundex code for the name 'Wojciechowski' so I can match it against historical census records that might have spelled it differently?”
