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, consecutive whitespace, tabs, and other whitespace characters cleaned and collapsed according to standard normalization rules.
Example use cases
Clean scraped web page text
“I just scraped some text from a web page and it's full of irregular spacing, multiple consecutive spaces, and random tabs — can you normalize all the whitespace so it's clean and readable?”
Preprocess text before NLP pipeline
“Before I run this customer feedback through my sentiment analysis model, I need to normalize all the whitespace in it — there are double spaces, trailing spaces, and mixed newlines that need cleaning up.”
Standardize pasted document content
“A user pasted this big block of text into our form and it has messy inconsistent spacing throughout. Can you clean up all the whitespace so it looks properly formatted?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.0007 USDC), pay-per-call whitespace normalization step in an autonomous agent pipeline — especially useful for preprocessing scraped, pasted, or OCR-extracted text before downstream NLP tasks, storage, or display. Ideal for agents on Base using x402 micropayments who need deterministic text cleaning without standing up their own infrastructure.
Side effects
- Text exceeds 50,000 character limit — returns an error indicating input is too long
- Empty text input — may return empty string or validation error
- Malformed request body missing 'text' field — returns 400-level error
- Payment failure via x402 protocol — returns 402 Payment Required if USDC payment not processed
