How this service works
Machine-readable settlement service
Output
Returns a JSON object containing the whitespace-normalized version of the input string, with leading/trailing whitespace trimmed and internal runs of whitespace collapsed to single spaces.
Example use cases
Clean user-submitted form input
“I'm getting form submissions with inconsistent spacing — lots of double spaces and stray tabs. Can you normalize the whitespace in this text: 'First Name: John Last Name: Doe'?”
Preprocess text before NLP pipeline
“Before I run sentiment analysis, I need to clean up this raw scraped text that has tons of irregular whitespace: 'The product was great but shipping was slow.' Can you normalize the whitespace?”
Fix copy-pasted document text
“I copied some text out of a PDF and it came out with weird spacing everywhere. Can you normalize the whitespace in this: 'Chapter 1: Introduction
This document outlines the key findings.'”

Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/text.normalize-whitespace--normalize-whitespaceWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call text whitespace normalization step without spinning up your own string processing logic. Ideal for preprocessing pipelines, cleaning user input, or sanitizing copy-pasted content before downstream NLP tasks. Best suited for single-string, synchronous use cases where cost per call is acceptable at $0.001 USDC.
Side effects
- Missing required 'input' field returns a validation error
- Non-string input may cause a 400 bad request
- Empty string input may return empty output or an error
- Network timeout if the service is unavailable
- Payment failure (402) if USDC balance is insufficient for the $0.001 fee
