Each URL renders on its first open and comes from cache after." source: https://bannx.com/solutions/publishers --- # A share image for every page you publish. Design the card once. Sign one URL per page with its title and author, put it in your og:image tag, and Bannx renders it on the first open. No image pipeline to run.

Mark the title, author and image as fields. 2. ### Sign the URLs Sign one URL per page, up to 500 in one request, or sign them in your own build with your space's secret. Signing is free. 3. ### Put it in the tag Use the URL as your og:image. A page shared a thousand times renders once. ## Start from a real template Free to open and edit, no account needed. - [Blog post OG cardOpen template](https://bannx.com/templates/blog-post-og-card) - [Code screenshot — editor window with tabsOpen template](https://bannx.com/templates/code-window-webgl-replica) - [YouTube — single speaker podcastOpen template](https://bannx.com/templates/youtube-single-speaker-podcast) - [Editorial quote card — squareOpen template](https://bannx.com/templates/editorial-quote-card-standalone) - [Typographic quote — squareOpen template](https://bannx.com/templates/typographic-quote-square) - [Quote card — portraitOpen template](https://bannx.com/templates/quote-card-portrait) ## Jobs publishing teams run - [OG images for blogsA share card for every post, from its title.](https://bannx.com/use-cases/og-images-for-blog) - [Signing in your buildSign URLs in your own code, with no API call per page.](https://bannx.com/docs/rendering#signing-offline) - [Act when a render finishesA signed webhook tells your system when an API render completes.](https://bannx.com/docs/webhooks) - [Cards made by agentsYour AI agent renders and signs the same images over MCP.](https://bannx.com/docs/integrations/mcp) ## What it runs on - [OG image APIA share image for every page from one signed URL, with no API call per page.](https://bannx.com/products/og-image-api) - [Image Gen APIImages, PDFs and video from your templates with one call.](https://bannx.com/products/image-gen-api) - [MCP ServerYour AI agent makes on-brand images, PDFs and video.](https://bannx.com/products/mcp) ## What it costs 25 free renders every month.

Email [[email protected]](https://bannx.com/cdn-cgi/l/email-protection#96f5f9f8e2f7f5e2d6f4f7f8f8eeb8f5f9fb). Is there an API key in the URL? No. The link carries a signature instead. Anyone can open it, but changing a value in it breaks the signature, so nobody can make your template say something else. What does each URL cost? Which formats and sizes? Can my build sign URLs without calling the API? Can I try it without an account? ## One template, a share image for every page. Try a template free, or read how signed URLs work.
