JavaScript rendering

We provide a complete solution that saves you from setting up proxies, browser fingerprinting, headless browsers, etc. Just set the render type in the header and you will receive a rendered result.

Rendering Type

You can choose between two rendering types:

• png（raw bytes that can be saved as PNG）

• html（The HTML of the rendered page）

Receives rendered page content in HTML format

curl --request POST --url https://unlocker-api.lunaproxy.com/request --header "Authorization: Bearer token" --header "content-type: application/json" --data "{\"url\":\"https://www.google.com/\",\"type\":\"html\",\"js_render\":\"False\"}" > google.html

The response will contain the raw bytes of an image that can be saved as a PNG format.

curl --request POST --url https://unlocker-api.lunaproxy.com/request --header "Authorization: Bearer token" --header "content-type: application/json" --data "{\"url\":\"https://www.google.com/\",\"type\":\"png\",\"js_render\":\"True\"}" > google.png
