## 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-b2953805 -d '<json body>'
```

Example prompt: Can you trim the whitespace from the start and end 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 text strings, especially in autonomous agent pipelines that already use x402 micropayments on Base. It is ideal for high-frequency, low-cost text sanitization tasks where spinning up a local function is undesirable or where you want a consistent, auditable API call in your workflow.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Missing required 'text' field in request body — validation error
- Payment failure via x402 (insufficient USDC balance or wallet misconfiguration) — 402 response
- Network timeout connecting to Cloudflare Worker — no response

## 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 all leading and trailing whitespace removed. The response schema is open (additionalProperties: true), so the exact field name(s) holding the result may vary.
