## 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 minia2a-uppercase-ratio-calculator-48fe48dc
```

Example prompt: What's the uppercase ratio of this text: 'Hello World, THIS is a TEST sentence'? I need to know what fraction of the characters are capitalized.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC) computation of the uppercase character ratio in a text string without setting up any local string-processing logic. Best for lightweight text quality checks, moderation pipelines, or formatting analysis.

## Known failure modes

- Missing or empty input string returns an error
- Non-string input types may cause parsing failures
- Very long strings may time out or return unexpected ratios
- Payment failure (402) if x402 payment header is missing or invalid

## How this service works

## Output
