How this service works
Convert text to upper, lower, title, sentence, camel, snake, or kebab case without calling an upstream model. Pay up to $0.001 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.
Output
A JSON object with an 'ok' boolean, 'tool' field set to 'caseConvert', the converted text result, and a 'fetchedAt' timestamp indicating when the conversion was performed.
Example use cases
Rename variables to snake_case
“Take this list of variable names — 'myVariableName', 'totalCountValue', 'userEmailAddress' — and convert them all to snake_case so I can use them in my Python script.”
Format article titles to title case
“I've got a bunch of blog post titles that are all lowercase and I need them properly formatted in title case before publishing — can you convert them for me?”
Generate camelCase keys from labels
“Convert these form field labels to camelCase so I can use them as JSON keys in my code: 'first name', 'date of birth', 'phone number'.”
