Rate limit: 300 requests per minute.
This endpoint allows you to update pipeline parameters for an existing stream. You can modify prompts, ControlNet settings, IP Adapter configuration, and other generation parameters.

​
Request Body Structure

{
  "pipeline": "streamdiffusion",
  "params": {
    "model_id": "Lykon/dreamshaper-8",
    "prompt": "new prompt",
    // ... only include parameters you want to change
  }
}
The pipeline field defaults to "streamdiffusion" if omitted, so you can just send params for most updates.

​
Hot-Swap vs Reload Parameters

The following parameters can be updated dynamically (no reload required):
  • prompt, negative_prompt
  • guidance_scale, delta
  • num_inference_steps, t_index_list
  • seed
  • controlnets.conditioning_scale
  • ip_adapter settings
  • ip_adapter_style_image_url
All other parameters trigger a full pipeline reload (~30s).

​
Example: Update Prompt

curl -X PATCH \
  "https://api.daydream.live/v1/streams/${STREAM_ID}" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer ${DAYDREAM_API_KEY}" \
  -d '{
    "params": {
      "model_id": "Lykon/dreamshaper-8",
      "prompt": "cyberpunk cityscape, neon lights"
    }
  }'

​
Example: Adjust ControlNet Strength

curl -X PATCH \
  "https://api.daydream.live/v1/streams/${STREAM_ID}" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer ${DAYDREAM_API_KEY}" \
  -d '{
    "params": {
      "model_id": "Lykon/dreamshaper-8",
      "controlnets": [
        {
          "model_id": "lllyasviel/control_v11f1p_sd15_depth",
          "preprocessor": "depth_tensorrt",
          "conditioning_scale": 0.7,
          "enabled": true
        }
      ]
    }
  }'
