How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns an object containing the whitespace-normalized version of the input text, with extraneous spaces, tabs, and line breaks collapsed or standardized according to whitespace normalization rules.
Example use cases
Clean scraped web content
“I just scraped some text from a webpage and it's full of weird spacing and tabs everywhere. Can you clean up all the whitespace so it reads normally?”
Prepare text for NLP pipeline
“Before I run sentiment analysis on this customer review, I need to normalize the whitespace — there are tons of extra spaces and newlines in it. Can you fix that for me?”
Fix copy-paste formatting issues
“I copied some text from a PDF and the spacing is all messed up with random double and triple spaces throughout. Can you clean it up so it looks like normal text?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/whitespace/t3?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, low-cost ($0.001 USDC) pay-per-call solution for whitespace normalization, especially in agentic pipelines on Base that already use x402 for micropayments. Ideal for cleaning scraped, copy-pasted, or OCR-extracted text before further processing.

- Empty or missing 'text' field — validation error returned
- Payment failure via x402 — 402 response before processing begins
- Malformed JSON body — 400 bad request
