## 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 pennyrail-text-slugify-url-slug-generator-723aeb98 -d '<json body>'
```

Example prompt: Turn 'Hello World! My First Blog Post (2024)' into a URL slug I can use as a permalink.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use text-to-slug conversion without standing up your own string-processing library or microservice. Ideal for low-volume, on-demand slug generation within agent pipelines that already use x402 micropayment infrastructure.

## Known failure modes

- Empty or missing 'input' field returns a validation error
- Extremely long strings may be truncated or cause timeout
- Non-UTF-8 encoded characters may be stripped or cause errors
- Payment failure (402) if USDC balance is insufficient or x402 header is missing
