1. Get started

Use RunComfy's API to run bytedance/seedream-5/lite/edit. For accepted inputs and outputs, see the model's schema.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/bytedance/seedream-5/lite/edit \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "Maintain the model’s pose and the flowing, liquid-like silhouette of the garment. Change the material from silver metal to completely transparent clear water (or glass). Through the flowing liquid, the model’s skin details should be visible. The lighting effect should shift from reflection to refraction.",
    "image": [
      "https://playgrounds-storage-public.runcomfy.net/tools/7321/media-files/input-1-1.png"
    ]
  }'

2. Authentication

Set the YOUR_API_TOKEN environment variable with your API key (manage keys in your Profile) and include it on every request as a Bearer token via the Authorization header: Authorization: Bearer $YOUR_API_TOKEN.

3. API reference

Submit a request

Submit an asynchronous generation job and immediately receive a request_id plus URLs to check status, fetch results, and cancel.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/bytedance/seedream-5/lite/edit \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "Maintain the model’s pose and the flowing, liquid-like silhouette of the garment. Change the material from silver metal to completely transparent clear water (or glass). Through the flowing liquid, the model’s skin details should be visible. The lighting effect should shift from reflection to refraction.",
    "image": [
      "https://playgrounds-storage-public.runcomfy.net/tools/7321/media-files/input-1-1.png"
    ]
  }'

Monitor request status

Fetch the current state for a request_id ("in_queue", "in_progress", "completed", or "cancelled").

curl --request GET \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/status \
  --header "Authorization: Bearer <token>"

Retrieve request results

Retrieve the final outputs and metadata for the given request_id; if the job is not complete, the response returns the current state so you can continue polling.

curl --request GET \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/result \
  --header "Authorization: Bearer <token>"

Cancel a request

Cancel a queued job by request_id, in-progress jobs cannot be cancelled.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/cancel \
  --header "Authorization: Bearer <token>"

4. File inputs

Hosted file (URL)

Provide a publicly reachable HTTPS URL. Ensure the host allows server‑side fetches (no login/cookies required) and isn't rate‑limited or blocking bots. Recommended limits: images ≤ 50 MB (~4K), videos ≤ 100 MB (~2–5 min @ 720p). Prefer stable or pre‑signed URLs for private assets.
