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 whitespace-normalized version of the input text, with irregular spacing collapsed to standard single spaces and leading/trailing whitespace removed.
Example use cases
Clean OCR-extracted document text
“I just extracted text from a scanned PDF using OCR and it's full of double spaces, random tabs, and weird gaps between words — can you normalize all the whitespace so it reads cleanly?”
Preprocess user-submitted form input
“A user submitted a bio field on our form and it has a ton of extra spaces and line breaks scattered throughout. Can you clean up the whitespace so it looks consistent before we store it?”
Fix spacing in scraped web content
“I scraped some article text from a website and the spacing is all over the place — multiple spaces between words, leading spaces on lines, etc. Please normalize the whitespace so it's clean and uniform.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t6?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call whitespace normalization step in an agent pipeline — especially when you want to avoid bundling heavy NLP libraries just for spacing cleanup. Ideal for preprocessing OCR output, user-submitted text, or scraped web content before feeding it into downstream models or databases. At $0.004 USDC per call it's cost-effective for high-volume text cleaning without infrastructure overhead.
Side effects
- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Payment not provided or insufficient — 402 response requiring x402 payment on Base
- Malformed JSON body — 400 error
- Network timeout on Cloudflare Workers edge
