Open Graph Image Generation API

If you do not use WordPress, call generation directly: the template lives in ogCover, and your site sends only variables.

How the flow works

  1. Article datatitle, author, category, image_url
  2. Templatelayers, fonts, colors, anchors
  3. Ready coverJPEG for websites and social previews

Where it fits

The API helps when images should be assembled during publishing or data updates, not manually inside a graphics editor.

  • dynamic previews for pages and catalog cards
  • editorial tools and internal CMS systems
  • bulk generation in one brand style

What your app sends

Usually you only need a template ID and a variables object: title, author, category, image_url, and whatever fields your template uses.

  • the API key stays on your server, never in the browser
  • quota is counted per successful generation
  • the response is a ready JPEG image

Questions

Can images be generated without browser rendering?

Yes. Rendering is handled by a separate engine, so you do not need to launch Chromium for every request.

Is the API meant for production?

Yes, but the API key should stay server-side and never be exposed in client code.
