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 Unicode characters with ASCII equivalents (accented letters, diacritical marks, special typographic characters) have been replaced or transliterated to their closest plain ASCII representations, and characters with no ASCII equivalent may be removed or replaced with a placeholder.
Example use cases
Sanitize user input for ASCII-only database
“I need to store user-submitted names in a legacy system that only accepts ASCII — can you fold all the accented characters in this list to their plain ASCII equivalents: 'Ångström, Müller, Chloé, Björk, Ñoño'?”
Normalize search index tokens
“Before indexing this product description, strip or fold any non-ASCII Unicode characters to ASCII so our search engine can handle it: 'Résumé templates for naïve résumés — über-professional designs by Ångström & Søren.'”
Clean scraped multilingual content
“I scraped some multilingual web content and need it ASCII-folded before running it through a downstream pipeline that only handles plain ASCII — here's the text: 'Über die Brücke, près du château, в центре города, até logo.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/ascii-fold/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, cheap ($0.001 USDC), pay-per-call ASCII folding of arbitrary Unicode text up to 50,000 characters — ideal for autonomous agents that need to preprocess multilingual or accented text for ASCII-only systems, search indexes, or legacy databases, and want to avoid spinning up local NLP libraries. Prefer this over self-hosted solutions when running in a stateless agent environment on Base/x402.
Side effects
- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error returned
- Payment failure via x402 protocol — 402 response with payment details
- Network timeout on Cloudflare Worker edge node
- Malformed JSON body — 400 bad request
