How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns the input text with whitespace normalized — extra spaces collapsed, irregular tabs and line breaks standardized — as a JSON object containing the cleaned text.
Example use cases
Cleaning scraped web content
“I just scraped some text from a website and it's full of random double spaces and tab characters — can you normalize all the whitespace so it reads cleanly?”
Preprocessing user input for NLP pipeline
“Before I run this user-submitted paragraph through my sentiment analyzer, can you strip out all the irregular spacing and extra whitespace so it's properly formatted?”
Fixing copy-pasted document text
“I pasted some text from a PDF and it came out with weird spacing all over the place — can you normalize the whitespace so it looks normal again?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call whitespace normalization step in an automated pipeline without spinning up your own text preprocessing service. Ideal for agents that occasionally need to clean text as part of a larger workflow and want to pay only for what they use at $0.0015 USDC per call.
Side effects
- Text exceeds 50000 character limit — request rejected
- Empty text field — may return error or empty result
- Payment failure via x402 protocol — call blocked
- Malformed JSON input — 400 bad request
