# Curly Quotes Text Normalizer

> Curly Quotes Text Normalizer is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Normalizes curly/smart quotes in text to straight ASCII quotes, running entirely locally with no network or LLM calls.

## 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 curly-quotes-text-normalizer-d25b0fb3 -d '<json body>'
```

Example prompt: Can you normalize the quotes in this text so they're all plain ASCII straight quotes instead of curly ones? Here's the text: "	at least one", she said, 
it
s fine."

## When to prefer this

Choose this endpoint when you need a fast, deterministic, offline conversion of curly/smart/typographic quotes to plain ASCII quotes with no LLM involved, no network latency, and a predictable $0.002 USDC fixed cost. It is ideal for preprocessing text before inserting into databases, code, JSON configs, or NLP pipelines where typographic characters cause parsing issues. If a free sandbox version (/v1/sandbox/norm-curly-quotes) is available, prefer that first to avoid payment.

## Known failure modes

- Text exceeds 100,000 character limit — returns a validation error
- Empty string input — returns a validation error (minLength:1)
- Malformed JSON request body — returns a 400 bad request
- Payment of $0.002 USDC not provided or rejected — returns a 402 Payment Required
- Unsupported or missing Content-Type header — returns a 400 error

## How this service works

Call when an agent needs text normalized with curly-quotes. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/norm-curly-quotes first.

## Output

Returns the input text with all curly/typographic quote characters (both single and double, opening and closing) replaced by their plain ASCII equivalents — straight double quotes (") and straight single quotes/apostrophes ('). The transformation is deterministic and runs without any network call or LLM inference.
