Guides

Operational depth for OGKit — beyond the HTTP reference. For SEO narrative, see the Open Graph SEO guide.

Quickstart — first OG image in 60 seconds
Playground → copy URL → HTML/Next.js meta → Facebook Debugger. No signup required.
Signed URLs & domain allowlists
HMAC-SHA256 signatures, Node/Python examples, dashboard toggles, error codes.
Auto OG from a page URL
GET /api/og/auto — extracted metadata, overrides, safety limits, Next.js pattern.
Caching & rescrape
Cache-Control, CDN keys, Facebook/LinkedIn/Slack refresh workflow.
Theme, accent, pattern, fonts
Brand the minimal and gradient templates without a custom renderer.
MCP for Cursor & AI agents
Connect /api/mcp, tools list, plugin bundle, safe agent workflow.
Troubleshoot blank, wrong, or stuck cards
Triage absolute URLs, key errors, signed URLs, and Facebook/LinkedIn/Slack rescrape.
Satori vs Puppeteer for OG images
When to own a renderer vs use a hosted 1200×630 template API.

OGKit turns one HTTPS URL into a 1200×630 Open Graph image. Read the API reference, deep guides, the Open Graph SEO guide, try the Playground, or sign in to create API keys.
