## 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-trim-61eddf63 -d '<json body>'
```

Example prompt: Trim the whitespace from the beginning and end of this text: '   Hello world, this is my document content that needs cleaning.   '

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call text trimming operation without spinning up your own infrastructure, especially in autonomous agent pipelines on Base using x402 micropayments. Useful when you want a reliable remote trim operation as part of a larger text normalization workflow.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Missing required 'text' field — validation error
- Payment failure via x402 protocol — call not processed
- Empty string input may return empty result

## How this service works

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