How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the cleaned version of the input text, with control characters and non-printable characters removed or normalized, ready for downstream processing.
Example use cases
Sanitize scraped web content
“I just scraped a bunch of web pages and the text has weird control characters and invisible junk in it — can you strip all of that out so it's clean plain text I can work with?”
Prepare user input for LLM
“A user submitted a form with some text that seems to have hidden control codes in it. Can you clean it up by removing any non-printable or control characters before I send it to the model?”
Fix exported data with embedded control sequences
“I exported some records from a legacy system and the strings have embedded control characters mixed in. Can you normalize all of that text to remove the control codes so the data is clean?”
