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-text-normalize-control-clean-93a301a5 -d '<json body>'
```

Example prompt: Clean up this raw text for me — strip out any control characters, null bytes, or non-printable sequences so it's safe to use downstream: "Hello\u0000World\r\nThis has\x01weird\x1Bchars".

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call utility to strip control characters and non-printable bytes from arbitrary text — especially in automated agent pipelines where raw input may come from scrapers, PDFs, user forms, or LLM outputs. Prefer it over general-purpose text cleaning libraries when you need a hosted, stateless, low-latency microservice with per-call micropayment pricing via x402.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Payment not provided or insufficient — HTTP 402 returned
- Malformed JSON body — parse error returned
- Empty text field — may return empty or error response
- Network timeout on Cloudflare Worker edge node

## 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 cleaned and normalized version of the input text, with control characters and non-printable sequences removed or standardized, ready for safe downstream use.
