How this service works
Rewrite text: Verb-path alias of POST /v1/cheap-errand ($0.01 USDC). Same handler + payment terms; path defaults task=rewrite when body.task omitted. Cheap agent glue for buyer-supplied text. Base via x402. No API key.
Output
Returns rewritten or paraphrased text derived from the input, processed according to the rewrite task. The response reflects the transformed content with improved clarity, tone, or style as applicable.
Example use cases
