How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object with a 'text' field containing the input string with all whitespace sequences collapsed into single spaces, resulting in a clean, uniformly spaced string.
Example use cases
Clean up user-submitted form input
“A user submitted a bio field on our form and it has tons of extra spaces and tabs all over it — can you normalize the whitespace so it reads cleanly: 'My name is John and I love coding.'”
Preprocess text before NLP analysis
“Before I run sentiment analysis on this customer review, I need to clean up the spacing — it came out of a PDF parser with tons of extra spaces: 'The product was great but delivery was slow.'”
Standardize scraped web content spacing
“I scraped this paragraph from a website and it has irregular whitespace everywhere — can you normalize it to single spaces so I can display it cleanly: 'Welcome to our store. We offer great deals daily.'”

Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/text/whitespace-normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, fast, paid-per-call whitespace normalization step in an agent pipeline, particularly when using x402-compatible micropayment infrastructure. Suited for preprocessing pipelines where consistent spacing is required before downstream NLP or display tasks, and where a managed API call is preferred over running custom string logic.
