How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the normalized, control-cleaned version of the input text with control characters removed and whitespace standardized. The exact output fields are dynamically typed but typically include the cleaned text string.
Example use cases
Sanitize scraped web content
“I just scraped a bunch of articles from the web and the text is full of weird control characters and non-printable junk. Can you run it through control-clean normalization to strip all that out before I feed it into my summarizer?”
Prep user input for NLP pipeline
“Before I send this user-submitted form text to my sentiment analysis model, I want to normalize and control-clean it to remove any hidden characters or odd whitespace. Here's the text: 'Thanks for the help!
Really appreciate it.'”
Fix copy-pasted document text
“I copied text out of a PDF and it's full of weird formatting artifacts and control codes — can you run the control-clean normalizer on it to give me a clean plain-text version?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/control-clean/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call text normalization step for an autonomous agent pipeline — especially useful for cleaning scraped, copy-pasted, or user-generated text of control characters and whitespace anomalies before feeding into NLP models, embeddings, or storage. At $0.001 USDC per call it is well-suited for high-volume preprocessing tasks where a lightweight sanitization pass is needed without a heavy ML model.
