# ONE Engine ASCII Fold Text Normalizer

> ONE Engine ASCII Fold Text Normalizer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).

Converts text containing non-ASCII characters into ASCII-only equivalents via Unicode folding (e.g. accents, diacritics, and special characters are stripped or transliterated).

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-engine-ascii-fold-text-normalizer-980626e3 -d '<json body>'
```

Example prompt: Can you ASCII-fold this text for me — strip out all the accents and special characters so it's plain ASCII: 'Héllo Wörld, naïve résumé from Ångström'?

## When to prefer this

Choose this endpoint when you need a cheap, per-call ASCII normalization of Unicode text — particularly for preprocessing international or user-submitted text before storage in ASCII-only systems, URL slug generation, or legacy database ingestion. It is well-suited for autonomous agent pipelines that need lightweight, pay-per-use text cleaning without spinning up a full NLP library.

## Known failure modes

- Text exceeding 50,000 characters may be rejected or truncated
- Missing required 'text' field returns a validation error
- Payment failure via x402 results in 402 Payment Required response
- Malformed JSON body returns 400 Bad Request
- Some obscure Unicode codepoints may not have defined ASCII mappings and could be dropped silently

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns an object containing the ASCII-folded version of the input text, where all non-ASCII characters have been transliterated or stripped to their closest ASCII equivalents (e.g. 'é' → 'e', 'ü' → 'u', 'ñ' → 'n').
