How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the whitespace-normalized version of the input text, with irregular spaces, tabs, and extra line breaks collapsed or standardized.
Example use cases
Clean scraped web content
“I just scraped a bunch of text from a webpage and it's full of weird spacing, tabs, and double spaces — can you normalize all the whitespace so it reads cleanly?”
Prepare text for NLP pipeline
“Before I run this document through my NLP model, can you normalize the whitespace so there are no inconsistent spaces or stray tabs messing up the tokenization?”
Fix copy-pasted document text
“I copied some text out of a PDF and it came out with crazy spacing everywhere — can you clean it up so it has proper single spaces and no extra line breaks?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call whitespace normalization step for text preprocessing — especially in agent pipelines where text is extracted from web scraping, PDF parsing, or OCR and contains irregular spacing. Ideal when you want a cheap ($0.018 USDC), stateless, single-purpose utility without building your own normalization logic.
Side effects

- Empty or missing 'text' field — validation error returned
- Payment failure via x402 — 402 response if USDC payment is not provided
- Network timeout on the Cloudflare Workers endpoint
- Unexpected characters or binary content causing processing errors
