PostCapture API

Quick start

1. 1

   Get a key

   API access is included with Pro and switches on automatically at checkout. Then create your own keys in the dashboard; they're prefixed with sk_.

2. 2

   Make a request

   POST the post URL to the v1 endpoint with your key in the Authorization header. Everything else is optional.

   cURL

   1curl -X POST https://postcapture.com/api/v1/screenshot \
   2  -H "Authorization: Bearer $POSTCAPTURE_API_KEY" \
   3  -H "Content-Type: application/json" \
   4  -d '{
   5    "postUrl": "https://x.com/postcaboron/status/1924847327370461555"
   6  }'

3. 3

   Get your screenshot

   You get back JSON with a url to the PNG, its dimensions and your remaining quota. The URL is valid for at least an hour and the image is deleted shortly after, so download it if you need it for longer. Prefer the raw bytes? Add "response": "image" to the body.
