## 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-text-normalize-control-clean-top-10-3a3e7034 -d '<json body>'
```

Example prompt: Clean this raw text by removing any control characters and normalizing it — here's the input: 'Hello\u0000 World\u0003\nThis is\u001F messy text with hidden\u0008 control chars.' Give me the top 10 cleaned segments.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call solution to strip control characters and normalize raw text — especially useful for text extracted from PDFs, scraped web pages, or user-submitted content that may contain non-printable or invisible characters. At $0.03 USDC per call it suits high-frequency agent pipelines where you pay only for what you use, with no subscription overhead.

## Known failure modes

- Text exceeding 50000 characters will likely be rejected or truncated
- Empty or whitespace-only input may return an empty result
- Payment failure via x402/Base may prevent the call from completing ($0.03 USDC required)
- Malformed JSON body (missing required 'text' field) returns a 4xx error
- Network timeout on Cloudflare Workers edge under high load

## 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 normalized, control-character-free version of the input text, structured as up to 10 cleaned segments or top-ranked cleaned text outputs, ready for downstream processing.
