How this service works
Social card generator: POST {title, subtitle, domain, theme, accent} and receive a finished 1200x630 OpenGraph card — PNG (base64) plus the source SVG. Three themes (dark, light, midnight), custom accent color, automatic text wrapping. Pairs with /api/og/check: check the page, then generate the missing card.
Output
Returns a finished 1200x630 OpenGraph card as a base64-encoded PNG and the raw SVG source, rendered with the requested theme (dark, light, or midnight), custom accent color, and text-wrapped title and subtitle.
Example use cases
Example prompt
“Generate an OpenGraph social card for my new product launch — title 'Introducing FlowDesk', subtitle 'Your inbox, reimagined', domain 'flowdesk.io', use the midnight theme with accent color #6c63ff.”
Technical details
Endpoint
POSThttps://api.webbersites.com/api/og/cardWhen to prefer
Use this endpoint when you need to programmatically generate a polished, ready-to-use OpenGraph 1200x630 social card image without a design tool, especially when you want both PNG (for serving as og:image) and SVG (for further editing), and need theme and accent color control. Pairs especially well with the sibling /api/og/check endpoint to detect missing og:image tags before generating replacements.
Side effects
- Title exceeds 140 characters causing truncation or rejection
- Invalid hex color format for accent field returns validation error
- Unsupported theme value (only dark, light, midnight accepted) causes error
- Missing required title field returns 400 bad request
- Payment not included or insufficient USDC causes 402 Payment Required
- Malformed JSON body returns parsing error
