How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the normalized and cleaned version of the input text, with control characters removed, whitespace standardized, and formatting artifacts corrected.
Example use cases
Cleaning scraped web content
“I just scraped a bunch of product descriptions from a website and they're full of weird control characters, random line breaks, and encoding junk. Can you run them through the T9 control-clean normalizer so the text is clean and usable?”
Preprocessing text for embedding pipeline
“Before I send these customer reviews to my embedding model, I need to normalize them — strip control characters, fix spacing, and standardize the format. Can you clean this batch of text using the control-clean T9 normalizer?”
Sanitizing user-submitted form input
“Users are submitting free-text feedback through our form and some of it has garbage characters and broken formatting. Run this text through the T9 control-clean normalizer to tidy it up before we store it.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/control-clean/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost ($0.018 USDC per call) pay-per-call text normalization step for up to 50,000 characters, especially in autonomous agent pipelines using x402 on Base where metered micropayment billing is preferred over subscription APIs. Best suited for preprocessing noisy text before NLP, embedding, or storage steps.
