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-clean-pack-t4-f0d21e7b -d '<json body>'
```

Example prompt: Clean up this raw text for me — it has weird formatting and extra whitespace — using the T4 tier: 'This is   some messy

text with   odd spacing and—special chars!!'

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.0018 USDC per call) text cleaning and normalization step in an agentic pipeline, particularly when operating on Base with x402 micropayment infrastructure. Prefer this over heavier NLP services when you just need noise removal and normalization rather than semantic analysis or transformation.

## Known failure modes

- Missing or empty 'text' field in request body returns an error response
- Payment not included or insufficient USDC via x402 results in 402 Payment Required
- Malformed JSON body returns a parse error
- Extremely long text strings may exceed processing limits
- Network timeouts on the Cloudflare Workers edge infrastructure

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output
