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 and control-character-normalized version of the input text, with non-printable and control characters removed or replaced according to the t4 cleaning tier.
Example use cases
Sanitize scraped web content
“I just scraped a bunch of text from a website and it's full of control characters and weird invisible formatting — can you clean it up so it's plain readable text I can process further?”
Fix OCR output before indexing
“This OCR output has tons of stray control codes and garbage characters mixed in with the real text. Can you normalize and clean it up before I index it?”
Prepare user input for NLP pipeline
“Before I run sentiment analysis on this user-submitted comment, can you strip out any control characters or non-printable junk so the text is clean?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/control-clean/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call solution to strip control characters and normalize text formatting without spinning up your own preprocessing pipeline. Ideal for agents processing scraped, OCR-generated, or user-submitted text that may contain non-printable characters. At $0.0015 USDC per call it's cost-effective for high-volume text sanitization tasks where a full NLP service would be overkill.
