How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A text string with whitespace normalized — multiple consecutive spaces, tabs, and irregular gaps collapsed into single spaces, yielding a clean, consistently spaced version of the input text.
Example use cases
Normalize scraped web content
“I just scraped some article text and it's full of irregular spaces, tabs, and double spaces everywhere — can you normalize all the whitespace so it reads cleanly?”
Preprocess text before NLP pipeline
“Before I run sentiment analysis on this customer feedback dump, clean up all the whitespace inconsistencies — extra spaces, stray tabs, that kind of thing.”
Fix formatting in user-generated content
“Users keep submitting form responses with messy spacing — multiple spaces between words, trailing whitespace, mixed tabs. Can you normalize all of that into clean single-spaced text?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call whitespace normalization step as part of a preprocessing pipeline — especially in agentic workflows where you want to clean scraped, extracted, or user-generated text before further NLP operations, without spinning up a local utility or embedding a library. The x402/Base micropayment model makes it cost-effective for high-frequency, per-document use.
Side effects
- Text exceeds 50,000 character limit — returns error
- Empty or missing 'text' field — returns validation error
- Non-string input for 'text' field — returns schema validation error
- Network timeout on large inputs near the character limit
