Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Can you roast my landing page at https://floortom.com — I want the GTM critique with persona feedback on the offer, focus, and durability, plus the SVG roast card?

## When to prefer this

Choose this endpoint when you need a fast, opinionated AI critique of a marketing or landing page from multiple buyer personas, including a visual SVG artifact suitable for sharing. It is especially useful for founders, growth marketers, or product teams wanting structured GTM feedback (offer/focus/durability) without a full human consultant. Prefer it over generic SEO audits when the goal is messaging quality and conversion narrative, not technical SEO.

## Known failure modes

- URL is unreachable or returns non-200 — roast cannot be generated
- URL is not a landing/marketing page (e.g. API endpoint, login wall) — classification may be inaccurate
- Page is JavaScript-heavy SPA and content cannot be fetched — incomplete critique
- URL parameter missing — 400 bad request
- Rate limiting or x402 payment failure — 402 Payment Required

## How this service works

## Output
