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 ASCII equivalents (e.g., 'é' becomes 'e', 'ü' becomes 'u', 'ñ' becomes 'n').
Example use cases
Search index normalization pipeline
“I need to normalize this product catalog text so that searches for 'cafe' also match 'café' — can you ASCII-fold all these names: 'Café Münster, Crêperie Düsseldorf, Señor Tacos'?”
Username sanitization for ASCII systems
“Our auth system only accepts ASCII usernames — can you ASCII-fold this display name so it's safe to use: 'Søren Ångström-Ñúñez'?”
Transliterate multilingual content for export
“I'm exporting this French/German article to a legacy system that only supports ASCII — please ASCII-fold the whole thing: 'L'été est là. Über die Brücke geht François avec naïveté.'”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/ascii-fold/t2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call ASCII folding operation without standing up your own Unicode normalization library. Ideal for agents that occasionally need to sanitize or normalize text for ASCII-only downstream systems, search index preparation, or username normalization — especially in automated pipelines where cost-per-call pricing is preferable to a subscription model. Best when text is under 50,000 characters and you need a fast, stateless conversion.
Side effects
- Text exceeds 50000 character limit — request rejected
- Payment not provided or insufficient USDC balance via x402 — 402 Payment Required response
- Malformed JSON body or missing required 'text' field — 400 Bad Request
- Empty string input may return empty output with no error
- Non-UTF8 binary content may cause unpredictable output
