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 ASCII-folded version of the input text, where non-ASCII characters (accented letters, diacritics, ligatures, special symbols) have been converted to their closest ASCII equivalents or removed.
Example use cases
Normalize multilingual product names
“I have a list of product names with French and German accents like 'Crème brûlée' and 'Straße' — can you fold them all to plain ASCII so they work in our legacy inventory system?”
Clean user-submitted form data
“Users are submitting names with accented characters like 'José García' and it's breaking our downstream database — can you convert this text to ASCII by folding out the diacritics?”
Prepare text for ASCII slug generation
“I need to turn this article title 'Ñoño en España: cómo viajar' into a plain ASCII version before I generate a URL slug from it — strip out all non-ASCII characters.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/ascii-fold/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call ASCII normalization operation without setting up your own Unicode library — ideal for agents that occasionally need to sanitize text for ASCII-only downstream systems, generate URL slugs, or clean user input with diacritics. Best for one-off or low-volume conversions where integrating a full Unicode library is overkill.
Side effects
- Text exceeding 50,000 characters may be rejected or truncated
- Payment failure via x402 if insufficient USDC balance on Base
- Malformed JSON request body returns an error
- Some exotic Unicode characters may be stripped entirely rather than folded if no ASCII equivalent exists
