Render Request

curl-example.sh

curl -X POST https://render-api.chillin.online/render/v1 \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d @request.json

Note: Our rendering requests are processed async. After submitting a request, you will immediately receive a response containing a render_id, which can be used to query the rendering status and results.

Prop	Type	Required	Example	Value Range	Description
compositeWidth	number	true	1920	720 - 3840	The width of the composite.
compositeHeight	number	true	1080	720 - 3840	The height of the composite.
fps	number	true	30	15 - 60	The frame rate of the composite.
projectData	object	true	-	-	The project data. Can be exported from the editor.

Note: The compositeWidth and compositeHeight can differ from the width and height specified in projectData. However, the aspect ratio of compositeWidth to compositeHeight must remain consistent with the aspect ratio of projectData.width to projectData.height.

This design allows the same video project to be exported in different resolutions while maintaining the original aspect ratio.

Get Render Result

After submitting an async render request, you can use the render_id to query the rendering status and result.

get-result-example.sh

curl -X POST https://render-api.chillin.online/render/result \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"render_id": 100000}'

Request Parameters

Prop	Type	Required	Example	Value Range	Description
render_id	number	true	100000	-	The render ID returned from the initial render request.

Success Render Response

result_response.json

{
"code": 0,
"data": {
  "render": {
    "create_at": "2025-06-27T12:37:21.684337Z",
    "json_url": "https://cloud.chillin.online/project_xxx.json?verify=xxx",

rendering: The render is currently being processed
success: The render completed successfully and the video is ready
failed: The render failed due to an error

Delete Render Files

Use this endpoint to permanently remove the rendered video file and project JSON for a completed task.

delete-render-files.sh

curl -X POST https://render-api.chillin.online/render/delete-files \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"render_id": 100000}'

Request Parameters

Prop	Type	Required	Example	Value Range	Description
render_id	number	true	100000	-	The render ID you want to clean up. Only renders in the success state can be deleted.

Sample Response

delete_response.json

{
"code": 0,
"data": {
  "message": "Render files deleted"
},
"msg": "success"
}

The delete action is irreversible and removes both the video and JSON assets.
Requests for renders that are still pending, rendering, or failed will be rejected.
