Topaz Video Upscale

Endpoint

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

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

Upscale an approved clip by 2×, 3× or 4×. The enhance_model selects the behavior: Proteus fits most footage; Artemis HQ/MQ denoises and sharpens a degraded source; Gaia HQ and Gaia CG refine rendered content; Nyx reduces noise only; Starlight HQ uses diffusion to restore and to upscale. target_fps enables frame interpolation. Run it on a clip that a generation model already approved. It does not change content and has no prompt.

Pricing

The unit is one source_second. Pricing key: topaz-video.

The credits come from the roasOS pricing table. No other field changes the price. To get the exact price of your request, send it with quote_only: true first.

Modes

• upscale

Provider endpoints: fal-ai/topaz/upscale/video.

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 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/topaz-video \
  -H "Authorization: Bearer roasos_sk_live_..." \
  -H "Idempotency-Key: 0f1c9e2a-topaz-video-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": 10, "expires_at": "...",
#        "confirmation": { "model": "topaz-video", "example": "10s_source" } } }

# 2. Run. Same body, same Idempotency-Key, quote_id in place of quote_only.
curl -X POST https://api.roasos.com/v1/video-edit/topaz-video \
  -H "Authorization: Bearer roasos_sk_live_..." \
  -H "Idempotency-Key: 0f1c9e2a-topaz-video-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": 10 } }

# 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/topaz-video is live. The price is the measured duration of the source clip, tiered by the measured source resolution, the upscale_factor and the effective frame rate (target_fps, or the measured source frame rate when you send none).
