How this service works
Legends Roast: any 1-2 of five cartoon legends roast the page's biggest flaw — score, verdict, shareable SVG. GET ?url=
Output
Returns a JSON object containing: the input URL, an SVG line-art roast card (viewBox 900x200), a punchy headline summarizing the main GTM issue found, and an array of five persona critiques (e.g. BEZOS) each with offer, focus, and durability assessments specific to that persona's lens.
Example use cases
Pre-launch landing page review
“We're about to launch next week and I want a brutal roast of our landing page at https://myapp.io — tell me what Bezos, a skeptical VC, and a confused first-time visitor would all hate about the offer and money journey.”
SaaS conversion rate audit
“Our SaaS sign-up page at https://plannerstack.com isn't converting and I can't figure out why — can you run the GTM roast and show me the persona critiques on offer clarity, focus, and durability?”
Shareable roast card for social
“I want a funny but honest landing page roast card I can share — run the GTM roast on https://driftboard.app and give me the headline and the SVG card I can post.”
Technical details
Endpoint
GEThttps://agentx.sale/x402/gtm-roast?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
