Website page card OG image template

This is a real render from the API with the example values below, at 1200×630.

The template behind auto OG images: one tag in your site template and every page gets this card, filled from its own title, description, icon and og:image — no fields to send. You can also render it like any other template. Without an image the title takes the full width and the site icon sits large in the corner; with no icon it shows the first letter of the site name.

Fields

Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.

Render it with one request

Use the slug as template. The response holds the URL of the finished PNG; ?wait=true keeps the connection open until it is ready.

curl -X POST "https://shareglint.com/v1/images?wait=true" \
  -H "Authorization: Bearer sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "template": "site-card",
    "modifications": {
        "title": "How we cut our image pipeline from 9 seconds to 900 ms",
        "description": "Cold starts, font loading and a Chrome pool: what actually made renders fast.",
        "site": "Northwind Blog",
        "url": "blog.northwind.dev/image-pipeline",
        "favicon": "https://example.com/images/logo-northwind.png",
        "image": "https://example.com/images/dashboard.png"
    }
}'

Or paste a signed URL into og:image

For static sites, Webflow, Shopify and no-code tools: put the fields in the query string and sign it with your signing secret. The first request renders the image, every later one is a redirect to the cached file. How to compute the signature.

<meta property="og:image" content="https://shareglint.com/i/acc_YOUR_ACCOUNT_ID/site-card.png?description=Cold%20starts%2C%20font%20loading%20and%20a%20Chrome%20pool%3A%20what%20actually%20made%20renders%20fast.&site=Northwind%20Blog&title=How%20we%20cut%20our%20image%20pipeline%20from%209%20seconds%20to%20900%20ms&url=blog.northwind.dev%2Fimage-pipeline&s=YOUR_SIGNATURE">

Make it yours

accent and theme change per request. For anything more, copy the template into your account: you get an ordinary HTML template with the same fields that you can edit in the dashboard or through the API. If the slug is free on your account, the copy takes it — your integrations switch to your version without changing a line.

curl -X POST "https://shareglint.com/v1/templates/library/site-card/copy" \
  -H "Authorization: Bearer sk_live_YOUR_KEY"
