## 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-slug-t3-01de8506 -d '<json body>'
```

Example prompt: Can you slugify this title for me — 'How to Build Autonomous AI Agents in 2025!' — so I can use it as a URL path segment?

## When to prefer this

Choose this endpoint when you need a reliable, low-cost, pay-per-call slug normalization utility without standing up your own infrastructure. Ideal for autonomous agents that occasionally need to slugify text as part of a larger workflow (e.g. CMS automation, SEO pipelines, URL generation) and want to pay only per call in USDC via x402 rather than managing a subscription or self-hosted service.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Payment failure via x402 — 402 response requiring USDC payment on Base
- Malformed JSON body — 400 bad request
- Cloudflare Worker timeout for extremely complex or edge-case text inputs

## 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 slugified, URL-safe version of the input text — typically lowercase, with spaces and special characters replaced by hyphens or removed, making it safe for use in URLs, filenames, or identifiers.
