## 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-3c285d75 -d '<json body>'
```

Example prompt: Can you trim the whitespace off the edges of this text for me: '   Hello, world!   '?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call microservice to trim whitespace from strings without standing up your own text processing infrastructure. Ideal for autonomous agents that occasionally need to normalize text inputs at very low cost ($0.0007 USDC per call) without bundling a full NLP or text processing library.

## Known failure modes

- Text exceeds 50,000 character limit — returns an error response
- Missing required 'text' field in request body — returns a validation error
- Payment failure via x402 — request rejected before processing

## 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 trimmed version of the input text, with leading and trailing whitespace removed.
