## 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-2-708691f7 -d '<json body>'
```

Example prompt: Clean up this messy scraped text for me — remove noise, normalize whitespace, and fix encoding artifacts: 'Hello,   world!!  

This   is  a   test...'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call text cleaning operation without committing to a subscription. Ideal for autonomous agents that sporadically need to sanitize or normalize text as part of a larger pipeline, especially when cost per call matters and tier-2 processing depth is sufficient.

## Known failure modes

- Empty or missing 'text' field returns an error or empty result
- Oversized text payloads may be rejected or truncated
- Payment failure via x402 will block the request with a 402 response
- Non-UTF-8 or binary input may produce unexpected output
- Network timeouts on Cloudflare Workers edge

## How this service works

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

## Output

Returns a JSON object with a 'tier' field (value 2) and a 'result' field containing the cleaned, normalized version of the input text after tier-2 processing.
