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 spaces, tabs, and extraneous newlines cleaned and standardized.
Example use cases
Preprocessing scraped web content
“I just scraped a bunch of web pages and the text is full of weird extra spaces and newlines. Can you normalize all the whitespace in this block of text before I run it through my embedding pipeline?”
Cleaning user-generated form input
“A user submitted a support ticket with all kinds of random double-spaces and stray tabs in it. Can you clean up the whitespace so it reads properly before I store it in the database?”
Fixing copied document formatting
“I pasted this text from a PDF and it's got inconsistent spacing all over the place. Can you normalize the whitespace so it's clean and readable?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call whitespace normalization step for text preprocessing pipelines — especially useful for cleaning scraped web content, user-generated text, or PDF-extracted strings before downstream NLP tasks like embedding, classification, or search indexing. Prefer this over regex-based approaches when you want model-aware normalization that understands natural language spacing conventions.
Side effects
