## 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-tier-3-bf2e196b -d '<json body>'
```

Example prompt: Clean up this messy scraped text for me — strip out the noise, normalize whitespace, and fix any encoding artifacts: 'Héllo   wörld!!  

  This is  raw   scrapëd   têxt...'

## When to prefer this

Choose this endpoint when you need lightweight, low-cost text cleaning and normalization for autonomous agent pipelines, especially when operating on Base with x402 micropayments. Tier 3 suggests a higher-quality or more thorough cleaning pass compared to lower tiers on the same service.

## Known failure modes

- Missing or empty text field returns an error
- Payment failure via x402 results in 402 response and no processing
- Extremely long text may be truncated or rejected
- Malformed JSON body returns a 400-level error
- Network timeouts on the Cloudflare Workers edge

## How this service works

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