Live demo

Product URL to OG image, live examples

Three product pages from VitalBuddies, the web shop run by Shotvik's maker, sent to POST /v1/og/from-url, plus one card from a built-in HTML template. No account needed to look.

Each card was rendered from the product page's own JSON-LD or Open Graph data, with the built-in default product card. No template, no manual edits.
The images on this page are static copies served from shotvik.com. Loading this page sends no request to the API.
"Open the live render" is a signed link to api.shotvik.com. It's served from Shotvik's opt-in cache, which keeps a render for up to 30 days, so the price on a live card can be up to 30 days old.
The live links run on a separate demo account with a hard monthly quota and a per-network limit. Visitors behind one shared office or mobile network share that limit, so under heavy load a live link can return 429 instead of an image. The copies here keep working.
The signature covers every parameter: change the product URL in a link and you get 401 invalid_signature. To render your own pages, create a free account.
