How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the uppercased version of the submitted text, with all alphabetic characters converted to their capital equivalents while non-alphabetic characters remain unchanged.
Example use cases
Normalize user input for matching
“Take this user-submitted product code 'abc-Widget-42x' and convert it to all uppercase so I can compare it against our inventory database.”
Format legal document header
“I need this clause title converted to all caps for a contract header: 'terms and conditions of service agreement' — can you uppercase it?”
Prepare data for CSV export
“I have a list of country names that need to be all uppercase before I export them to a CSV — can you convert 'united states, canada, united kingdom, australia' to uppercase?”
