## 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-00738068 -d '<json body>'
```

Example prompt: Can you ASCII-fold this text for me — convert all the accented and special unicode characters to their closest plain ASCII equivalents: 'Héllo Wörld, thïs is à tëst with café and naïve résumé'?

## When to prefer this

Choose this endpoint when you need cheap, fast, per-call ASCII folding/diacritic stripping without standing up your own text processing pipeline. At $0.0005 USDC per call via x402 on Base, it's ideal for AI agents that need occasional or bursty text normalization without managing infrastructure. Prefer this over whitespace-cleaning siblings when the primary problem is Unicode/diacritic characters rather than whitespace layout.

## Known failure modes

- Text exceeds 50000 character limit — request rejected
- Empty text field — validation error returned
- Payment failure via x402 protocol — 402 response with payment details
- Malformed JSON body — 400 bad request
- Network timeout on Cloudflare Workers edge — retry recommended

## 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 plain ASCII equivalents (e.g. 'é' becomes 'e', 'ü' becomes 'u', 'ñ' becomes 'n').
