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 accented and non-ASCII Unicode characters have been replaced with their closest plain ASCII equivalents (e.g. 'é' becomes 'e', 'ü' becomes 'u', 'ñ' becomes 'n').
Example use cases
Normalize multilingual product names
“I have a list of product names from our European catalog that contain accented characters like ü, ö, ñ, and é — can you ASCII-fold them all so they work in our legacy inventory system that only handles plain ASCII?”
Sanitize user input for search indexing
“Before I index these user-submitted review titles into our search engine, can you strip all the diacritics and convert any special Unicode characters to ASCII? Here's the text: 'Björk's café in Zürich — très magnifique!'”
Prepare foreign text for slug generation
“I need to turn this article title into a URL slug, but it has accented characters that will break the URL — can you ASCII-fold it first: 'La réunion à Genève: résultats préliminaires'?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/ascii-fold/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cheap, fast, per-call ASCII folding/diacritic stripping without standing up your own text processing pipeline. At $0.0005 USDC per call via x402 on Base, it's ideal for AI agents that need occasional or bursty text normalization without managing infrastructure. Prefer this over whitespace-cleaning siblings when the primary problem is Unicode/diacritic characters rather than whitespace layout.
