These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.

For agencies, hosting, SEO and developer tools sharing a site's performance, accessibility, best practices and SEO scores. Rings are clamped to 0–100 and turn red under 50, orange under 90 and green from 90; the number shown is the one you sent. Wide frames show four gauges in a row with the screenshot on the right, cropped from its top; square and vertical frames put the screenshot above a two-by-two grid.

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": "lighthouse-scores",
    "modifications": {
        "url": "northwind.dev/pricing",
        "scores": "Performance:87, Accessibility:100, Best practices:96, SEO:100",
        "device": "mobile",
        "date": "Oct 26, 2026",
        "screenshot": "https://example.com/images/phone-app.png",
        "logo": "https://example.com/images/logo-northwind.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/lighthouse-scores.png?date=Oct%2026%2C%202026&device=mobile&scores=Performance%3A87%2C%20Accessibility%3A100%2C%20Best%20practices%3A96%2C%20SEO%3A100&url=northwind.dev%2Fpricing&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/lighthouse-scores/copy" \
  -H "Authorization: Bearer sk_live_YOUR_KEY"
