## 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-trim-e844c874 -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 simple, reliable, pay-per-call text trimming operation within an autonomous agent pipeline running on Base via x402, especially when you want minimal overhead and no authentication setup beyond micropayment.

## Known failure modes

- Missing 'text' field in request body returns an error
- Non-string value for 'text' may cause processing failure
- Payment failure (402) if USDC balance is insufficient for the $0.0009 per-call fee
- Empty string input returns an empty string with no error

## How this service works

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

## Output
