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 excessive spaces collapsed, leading/trailing whitespace trimmed, and spacing characters standardized throughout the string.
Example use cases
Cleaning scraped web content
“I just scraped some article text from a webpage and it's full of weird spacing, double spaces, and stray tabs — can you normalize all the whitespace so it reads cleanly?”
Preprocessing text before AI analysis
“Before I feed this document into my summarizer, can you strip out all the extra spaces and normalize the whitespace so the text is consistent?”
Fixing copy-paste formatting issues
“I copied some text from a PDF and it has tons of extra spaces and broken line spacing — can you normalize the whitespace to make it a clean single-spaced string?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t8?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, pay-per-call whitespace normalization step for text preprocessing pipelines in autonomous agent workflows, especially when you want to avoid spinning up your own text-cleaning logic. At $0.01 USDC per call via x402 on Base, it's ideal for lightweight, high-frequency preprocessing tasks where text cleanliness is required before downstream NLP, indexing, or analysis operations.
Side effects
- Text exceeds 50,000 character limit — request rejected with validation error
- Empty or missing 'text' field — returns 400-level error
- Payment not included or insufficient — returns HTTP 402 requiring $0.01 USDC via x402 on Base
- Malformed JSON body — returns parse error
- Upstream Cloudflare Worker timeout — returns 5xx error
