Capture a screenshot or create a scrolling GIF animation with a simple GET request:
using HTTP
response = HTTP.get(
"https://api.scrnpix.com/screenshot?url=https%3A%2F%2Fexample.com&width=1280&height=720&format=png",
["X-KEY" => "your-api-key"]

)
write("animation.gif", response.body)Response Format
On success, the API returns the image binary data directly in the response body.

Frequently Asked Questions
Do I need to install any browser dependencies for Julia?
No. Scrnpix runs browsers on our infrastructure. You only need HTTP.jl to make HTTP calls.
Can I use this with Pluto notebooks?
Yes. Scrnpix works with any Julia environment — Pluto notebooks, Genie web apps, or plain Julia scripts.
How do I handle errors in Julia?
Check the response status with HTTP.status(). A 200 status means success with image bytes in HTTP.body(). Use try-catch for error handling.
What Julia version is required?
Julia 1.6+ with HTTP.jl support. The API is a simple HTTP GET request.
