# 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, $0.03/call, status unknown (last checked 2026-10-02).

Converts text up to 50,000 characters to ASCII by folding/transliterating Unicode characters to their closest ASCII equivalents.

## 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-f411b67c -d '<json body>'
```

Example prompt: Take this text and fold all the Unicode and accented characters down to plain ASCII — here it is: 'Héllo wörld, Ñoño café résumé naïve'

## When to prefer this

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.

## Known failure modes

- 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

## 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.
