curl -X POST https://mintrender.com/v1/render \  -H "Authorization: Bearer $MINTRENDER_KEY" \  -H "Content-Type: application/json" \  -d '{  "template": "YOUR_TEMPLATE_ID",  "data": {    "avatar": "",    "name": "Sam Rivera",    "handle": "@samrivera",    "quote": "Ship small changes often. A small change is easy to check and easy to undo.",    "date": "1 Nov 2026"  },  "format": "png"}'

Signed link

Put a link like this in an image tag or an og:image tag. Your server signs it with the link key of your workspace. We make the image the first time someone opens the link. How to sign links.
