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 all non-ASCII Unicode characters (accents, diacritics, ligatures, etc.) have been transliterated to their closest ASCII equivalents or removed.
Example use cases
Sanitize user input for legacy systems
“I have this user-submitted text full of accented characters and special Unicode letters that needs to go into our old ASCII-only database — can you convert it to plain ASCII? The text is: 'François Müller submitted a résumé from São Paulo.'”
Normalize product names for search indexing
“These product names have all sorts of accents and diacritics that are breaking our search index — normalize them to ASCII: 'Jalapeño sauce, Crème brûlée mix, Ångström measuring kit, Naïve Natural Yoghurt.'”
Clean multilingual filenames
“I need to rename these files to ASCII-safe names for our file system — strip the accents and special characters from these: 'Ñoño_report.pdf, café_menu_été.docx, über_analysis_2024.xlsx'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/ascii-fold/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, pay-per-call ASCII normalization without spinning up your own Unicode library, especially in agent pipelines where text from international sources must be sanitized for downstream ASCII-only systems (databases, filenames, search indexes). At $0.03 per call it is cost-effective for occasional normalization tasks and ideal for autonomous agents using x402 on Base for micropayments.
Side effects
- Text exceeding 50,000 characters may be rejected or truncated
- Missing required 'text' field returns a validation error
- Payment failure (x402) if USDC balance is insufficient or wallet not configured
- Non-string input types may cause schema validation errors
- Network timeout on Cloudflare Workers edge if request is malformed
