## 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 aiskills402-seo-meta-writer-8901909a
```

Example prompt: Write an SEO title and meta description for my page about organic dog food — keep the title under 60 characters and the meta description under 155 characters, in English, and make sure it matches what someone searching for 'organic dog food delivery' would want.

## When to prefer this

Choose this endpoint when you need a reusable, agent-native skill file for writing SEO meta tags rather than a one-off API call that returns generated text directly. It is ideal for agents that need to internalize SEO writing rules and apply them repeatedly across many pages without per-call pricing. Prefer it over generic LLM prompting when you want opinionated, tested character-limit rules and language-matching behavior baked in.

## Known failure modes

- Payment not received or x402 authorization missing — returns HTTP 402 Payment Required
- Invalid or expired payment token — returns 402 or 401
- Server unavailable — returns 500 or timeout
- File temporarily unavailable — returns 404 or 503
