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 input text with all whitespace normalized — multiple consecutive spaces, tabs, and irregular newlines collapsed into consistent single spaces, with leading/trailing whitespace trimmed.
Example use cases
Clean scraped web content
“I just scraped some HTML text and it's full of weird spacing and tabs. Can you normalize all the whitespace so it's clean and readable before I pass it to another tool?”
Prepare text for NLP pipeline
“Before I run sentiment analysis on this customer review, can you clean up the whitespace? The text has a bunch of extra spaces and irregular gaps that might mess up the tokenizer.”
Fix copy-pasted document text
“I copied this paragraph from a PDF and it came out with tons of double spaces and random tabs all over the place. Can you normalize the whitespace so it reads properly?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, fast, pay-per-call whitespace normalization step for text preprocessing pipelines — especially when running autonomous agents that need to clean up scraped, copy-pasted, or user-supplied text before passing it to NLP tools, LLMs, or storage. At $0.0005 USDC per call on Base via x402, it's cost-effective for high-volume text cleaning without a subscription.
Side effects
- Text exceeds 50,000 character limit — returns an error response
- Empty or missing 'text' field — returns a validation error
- Payment failure via x402 protocol — returns 402 Payment Required before processing
