## 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-to-slug-normalizer-top-10-df66bc98 -d '<json body>'
```

Example prompt: Can you slugify the title 'The Quick Brown Fox Jumps Over the Lazy Dog!' and give me the top 10 slug options I can use for a blog post URL?

## When to prefer this

Choose this endpoint when you need multiple slug options ranked by quality rather than a single deterministic output, especially when dealing with multilingual, special-character-heavy, or ambiguous text where the best slug choice is non-obvious. Prefer it over hand-rolled slugification for agentic pipelines that need reliable, pay-per-call utility without managing infrastructure.

## Known failure modes

- Text exceeding 50,000 characters returns a validation error
- Empty or whitespace-only text may return an empty slug list or error
- Non-UTF8 or malformed input may cause a parsing error
- Payment failure (x402) results in a 402 Payment Required response before processing

## How this service works

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

## Output

Returns an object with up to 10 ranked slug candidates derived from the input text, each being a lowercase, URL-safe string with special characters removed or replaced.
