VEED Background Removal Fast

Endpoint

POST https://api.roasos.com/v1/video-edit/veed-fast

Send your API key as a bearer token. The key needs the scope api:write. Every paid request also needs an Idempotency-Key header.

The envelope fields quote_only, quote_id, webhook_url and wait_timeout_seconds behave the same on each model endpoint. Refer to Jobs and Quotes and credits.

Good at

Cut out a person or an object from a clip for a composite. Use it when speed and price matter more than edge quality. Use /v1/video-edit/veed-standard when hair, fur or thin objects matter. Use /v1/video-edit/bria when you need a solid background color, a clip container other than WebM, or audio kept. It has no prompt and no creative control; the operation is deterministic.

Pricing

The unit is one source_30_frames. Pricing key: veed-fast.

The credits come from the roasOS pricing table. roasOS counts the frames of the source video. One unit is 30 frames, rounded up: a 5-second clip at 24 fps has 120 frames, which is 4 units. All frame rates are accepted. refine_foreground_edges: true uses the higher rate per unit. No other field changes the price. To get the exact price of your request, send it with quote_only: true first.

Modes

• background-remove

Provider endpoints: veed/video-background-removal/fast.

Request fields

The schema is strict. A field that is not in this table gets 400 unsupported_option. The field names are the roasOS role names. One role has one name in every family.

Media

This endpoint accepts these media roles:

• video_url — the source video

Every other role is refused: avatar_id, elements, product_id, product_images, references, reference_images, image_url, end_image_url, scene_id, scene_image, video_urls, audio_urls, audio_url, voice_id. A refused role gets 400 unsupported_option.

Prompt

None. The endpoint has no prompt.

Not exposed

These catalog entries describe omitted inputs, pinned values and source constraints. They do not imply that the provider accepts every listed field.

• output_codec — pinned to vp9.

Result

The result kind is video. Always present: url.

{
  "data": {
    "id": "gen_…",
    "kind": "video",
    "model": "veed-fast",
    "status": "completed",
    "result": {
      "url": "https://cdn.roasos.com/workspaces/ws_01/result"

}

The files are immutable objects on https://cdn.roasos.com. A result URL is a valid media input for your next request.

Example

The three steps are always the same: quote, run, poll.

# 1. Quote. Nothing is spent.
curl -X POST https://api.roasos.com/v1/video-edit/veed-fast \
  -H "Authorization: Bearer roasos_sk_live_..." \
  -H "Idempotency-Key: 0f1c9e2a-veed-fast-0001" \
  -H "Content-Type: application/json" \
  -d '{"quote_only":true,"video_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/video_url.mp4"}'
# 200 { "data": { "kind": "quote", "quote_id": "q_7Hk...", "credits": 1, "expires_at": "...",
#        "confirmation": { "model": "veed-fast", "example": "10s_source_30fps" } } }

# 2. Run. Same body, same Idempotency-Key, quote_id in place of quote_only.
curl -X POST https://api.roasos.com/v1/video-edit/veed-fast \
  -H "Authorization: Bearer roasos_sk_live_..." \
  -H "Idempotency-Key: 0f1c9e2a-veed-fast-0001" \
  -H "Content-Type: application/json" \
  -d '{"quote_id":"q_7Hk...","video_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/video_url.mp4"}'
# 201 { "data": { "id": "gen_...", "status": "queued", "credits_reserved": 1 } }

# 3. Poll, then read the result.
curl https://api.roasos.com/v1/jobs/gen_.../status -H "Authorization: Bearer roasos_sk_live_..."
curl https://api.roasos.com/v1/jobs/gen_.../result -H "Authorization: Bearer roasos_sk_live_..."

Today

POST /v1/video-edit/veed-fast is live. POST /v1/generations accepts image, video, audio, lipsync only, so this endpoint is the only public surface; the app's Remove background tool uses the same endpoint. The price is the number of frames in the source clip, measured by roasOS: one unit is 30 frames, rounded up. All frame rates are accepted; a 5-second clip at 24 fps is 120 frames, which is 4 units. refine_foreground_edges: true uses the higher rate per unit.
