How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the trimmed version of the input text, with leading and trailing whitespace removed. The exact response shape may vary but will include the processed text result.
Example use cases
Clean user input before storage
“Take this user-submitted form field value and strip any leading or trailing spaces from it before I save it to the database: ' John Doe '”
Normalize agent-generated output
“The text my pipeline just produced has extra whitespace padding at the start and end — can you trim it so it's clean? Here it is: '\n\n Some generated content here. \n'”
Preprocess text before sentiment analysis
“Before I run sentiment analysis, I need to normalize this review text by trimming any surrounding whitespace: ' The product was absolutely fantastic! '”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/trim/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call text trimming operation without setting up your own string-processing infrastructure. Ideal for autonomous agents that occasionally need to normalize text as part of a pipeline and want a simple, cheap utility call (at $0.0015 USDC) rather than spinning up a full text-processing service. Best for single text inputs up to 50,000 characters.
Side effects

- Missing required 'text' field in request body — validation error
- Insufficient USDC balance for x402 micropayment — payment failure
