v2026.5.2: Video generation with Google Veo

Generate video through osmAPI. Six Google Veo models (3.1, 3.1 Fast, 3.1 Lite, 3, 3 Fast, 2) are live behind a new async /v1/videos API — text-to-video, image-to-video, first/last-frame interpolation, up to 3 reference images, and video extension. Per-second metered billing, plus a dedicated Video Studio in the Playground.

Video generation API

Video generation is a long-running job. You create a job, poll it until it finishes, then download the MP4:

# 1. Create
curl https://api.osmapi.com/v1/videos \
  -H "Authorization: Bearer $OSM_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "veo-3.0-fast-generate-001",
    "prompt": "A cinematic shot of a mango tree swaying at dusk",
    "aspect_ratio": "16:9",
    "resolution": "720p",
    "duration": 8
  }'
# → 202 { "id": "vid_…", "status": "in_progress", "polling_url": "/v1/videos/vid_…" }

# 2. Poll until status == "completed"
curl https://api.osmapi.com/v1/videos/vid_… -H "Authorization: Bearer $OSM_KEY"

# 3. Download the MP4
curl -L https://api.osmapi.com/v1/videos/vid_…/content \
  -H "Authorization: Bearer $OSM_KEY" -o video.mp4

# 1. Create
curl https://api.osmapi.com/v1/videos \
  -H "Authorization: Bearer $OSM_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "veo-3.0-fast-generate-001",
    "prompt": "A cinematic shot of a mango tree swaying at dusk",
    "aspect_ratio": "16:9",
    "resolution": "720p",
    "duration": 8
  }'
# → 202 { "id": "vid_…", "status": "in_progress", "polling_url": "/v1/videos/vid_…" }

# 2. Poll until status == "completed"
curl https://api.osmapi.com/v1/videos/vid_… -H "Authorization: Bearer $OSM_KEY"

# 3. Download the MP4
curl -L https://api.osmapi.com/v1/videos/vid_…/content \
  -H "Authorization: Bearer $OSM_KEY" -o video.mp4

Capabilities

Text-to-video — prompt only, with native audio on Veo 3/3.1.
Image-to-video — pass an image (data URL or { data, mime_type }).
Interpolation — add a last_frame to define the closing shot.
Reference images — up to 3 reference_images to keep a subject consistent (Veo 3.1 / 3.1 Fast).
Video extension — extend a prior clip by ~7s via source_video_id (Veo 3.1 / 3.1 Fast, 720p).
Controls — aspect_ratio (16:9 / 9:16), resolution (720p / 1080p / 4k), duration, negative_prompt, seed, person_generation.

Constraints are enforced for you: 1080p/4k and reference images require an 8s clip, extension output is 720p, and person_generation is set automatically to match the input mode.

Pricing

Veo is metered per second of generated video, by resolution tier:

Model	720p / sec	1080p / sec	4k / sec
Veo 3.1	$0.40	$0.40	$0.60
Veo 3.1 Fast	$0.10	$0.12	$0.30
Veo 3.1 Lite	$0.05	$0.08	—
Veo 3	$0.40	$0.40	—
Veo 3 Fast	$0.10	$0.12	$0.30
Veo 2	$0.35	—	—

Blocked or failed generations are not charged.

Playground

A dedicated Video Studio is live in the Playground — pick a Veo model, write a prompt, and the available options (resolutions, durations, reference images, extension) adapt to the model you choose. A live cost estimate is shown before you generate.
