The Sora 2 API turns a one-line prompt into our launch teasers — fast iteration when we are A/B-testing creatives at scale.
The Sora 2 API generates short videos with synchronized audio from natural-language prompts (OpenAI Sora 2). The Sora 2 API renders 4 / 8 / 12-second 720p clips with physics-aware motion and broader stylistic range than the original Sora — all through one REST endpoint, priced 5% below the official published Sora 2 rate.

Use the Sora 2 API to generate videos with synchronized audio from natural-language prompts.
The Sora 2 API generates short videos with synchronized audio from natural-language prompts (OpenAI Sora 2). The Sora 2 API renders 4 / 8 / 12-second clips at 720p — physics-aware motion, accurate camera dynamics, broader stylistic range than the original Sora — all through one REST endpoint.
Pricing on the Sora 2 API is 5% below the official published rate: $0.34 per 4-second 720p clip, $0.76 at 8s, $1.14 at 12s. Audio is synthesized in the same call — no separate TTS pass. The Sora 2 API uses one RouterBase key — no provider-specific SDKs.
Six reasons teams ship on the Sora 2 API
From physics-aware motion to synchronized audio in one call — what the Sora 2 API gets right.
Natural-language video
Describe the scene in plain English; the Sora 2 API renders a 4 / 8 / 12-second clip from the prompt — no storyboard, no timeline editing.
Synchronized audio
The Sora 2 API generates audio inside the same call — voice, ambience, foley already aligned to the rendered motion. No separate TTS pass.
Physics-aware motion
Improvements over the original Sora in physical dynamics — collisions, gravity, fluids, camera parallax — let the Sora 2 API render believable motion without manual rigging.
4 / 8 / 12-second clips
Pick the duration per Sora 2 API call (4s default). Longer clips scale linearly in cost; the same prompt format handles every length.
720p output
The Sora 2 API (basic) renders at 720p (1280×720). For 1080p output and additional portrait/landscape sizes, see Sora 2 Pro.
5% off the official list
Pay 5% less than the official published Sora 2 rate when calling through the Sora 2 API. $0.34 per 4-second clip, $0.76 at 8s, $1.14 at 12s — flat across prompt complexity.
Quickstart
Get started with the Sora 2 API in 3 steps
From sign-up to your first Sora 2 API call in under 5 minutes.
Create a RouterBase API key
Sign up and generate sk-rb-… — one key works for the Sora 2 API and 200+ other models.
POST to the Sora 2 API endpoint
Send a prompt in JSON. The Sora 2 API is async — RouterBase polls upstream until the render completes (typically 1–3 minutes), then returns a signed URL with the audio-aligned clip.
Inspect the result
Each Sora 2 API response includes generation metadata for auditing and a render URL ready to embed in your product.
Pay only for what you use
RouterBase passes through partner-tier pricing. Compared against the model's official published API rate.
| Resolution | RouterBase | Official | Save |
|---|---|---|---|
| 4s | $0.340 | −15% | |
| 8s | $0.680 | −15% | |
| 12s | $1.020 | −15% |
Your request will cost $0.340 per run (4s).With $1 you can run this model approximately 2 times.
What teams build with the Sora 2 API
Real production loads running on the Sora 2 API and the RouterBase model catalog.
We swapped three providers through RouterBase in one line of code when OpenAI had its outage. Our users never noticed.
The Sora 2 API's physics handling on cloth and water is the difference between 'usable demo' and 'we can ship this'.
Synchronized audio inside one Sora 2 API generation removed an entire post-processing step from our pipeline.
Plugged the Sora 2 API into my existing OpenAI SDK with one base URL swap — less work than writing this testimonial.
RouterBase puts 200+ models behind one key. Our research team stopped asking for new provider accounts.
The Sora 2 API at $0.34 per 4-second clip means we sample broadly during creative iteration without burning budget.
We migrated 42 services to RouterBase over a weekend. The only PR comment we got was 'wait, that's all?'.
The Sora 2 API is 5% below the official published rate at every duration — at our scale that's six figures saved per quarter on video alone.
Frequently Asked Questions
Common questions about the Sora 2 API.
The Sora 2 API is RouterBase's pass-through to OpenAI Sora 2 text-to-video. It generates 4 / 8 / 12-second clips with synchronized audio from a natural-language prompt — improvements over the original Sora in physical motion, camera dynamics, and stylistic range.
