How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
Returns a rewritten version of the submitted text with the tone adjusted according to the instructions provided in the input field, wrapped in a result object with a status indicator.
Example use cases
Professionalizing casual Slack messages
“Take this Slack message I'm about to send to a client and make it sound more formal and polished: 'yo we ran into some bugs, stuff is kinda broken rn, we're on it tho'”
Making formal text more approachable
“This legal disclaimer sounds way too stiff — can you rewrite it in a friendlier, more conversational tone so our customers don't tune it out? Here it is: 'The aforementioned party hereby assumes all liability for consequential damages arising from use of the product.'”
Softening critical feedback
“I need to give my colleague some tough feedback but I don't want it to sound harsh — can you rewrite this to sound more constructive and encouraging? The text is: 'Your report was disorganized and missed the key points entirely.'”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/content/shift-toneWhen to prefer
Choose this endpoint when you need a quick, pay-per-call tone transformation without setting up a full LLM pipeline. Ideal for agents that occasionally need to rewrite text for different audiences (formal vs. casual, empathetic vs. assertive) without managing prompt engineering or model selection. The flat $0.10 USDC per-call pricing makes it cost-predictable for low-to-medium volume use cases.
Side effects
- Empty input string returns an error
- Ambiguous tone instruction may produce inconsistent output
- Very long text inputs may be truncated or produce degraded results
- Malformed JSON body returns a 400 error
- Payment failure via x402 protocol results in a 402 response before processing
