Seedance 2.0 Video AI API
Seedance 2.0 Video AI API: ByteDance text-to-video via REST from $0.096/sec at 480p up to $0.96/sec at 4K
Per-second pricing you can actually forecast is why this earns a slot in a production pipeline: 480p at $0.096/sec makes prompt iteration almost free, and 4K at $0.96/sec is a number you budget against instead of discovering on an invoice. The submit-and-poll API with real JS, Python and cURL samples is about as low-friction as video APIs get. Just check your durations first — Seedance 2.5 on the same platform runs 4 to 30 seconds, and this stops at 15.

Skip Seedance 2.0 if you need clips longer than 15 seconds or hand-controlled keyframing — Seedance 2.5 on the same platform runs to 30 seconds, and an editing suite gives you the frame-level control an API can't.
Longer clips multiply the per-second rate directly: a 15-second 4K render costs $14.40 at $0.96/sec, so duration is the single biggest lever on your bill.
Seedance 2.0 fits teams that can fund a prepaid credit balance and forecast seconds of output — the entry point is a one-time $10 package, and the $100 and $200 packages add a 3% bonus. Per second it undercuts Seedance 2.5 on the same platform (2.0 runs $0.096/sec at 480p versus 2.5 at $0.180/sec) and Kling 3.0 Turbo image-to-video at $0.1200/sec for 1080p, but sits above Wan 3.0 image-to-video at $0.1800/sec for 1080p only when you compare like resolutions.

About Seedance 2.0 Video AI API
Seedance 2.0 Video AI API is ByteDance's text-to-video model delivered through Flaq AI's REST layer, aimed at developers who want video generation inside their own product rather than a browser editor. The workflow is two calls: POST a JSON body to api.flaq.ai/api/v1/video/task with model_name seedance-v2.0-text-to-video, a prompt, resolution, duration, aspect ratio and a sound flag, then poll /api/v1/video/{task_id} until it returns a video URL. Flaq publishes working JavaScript, Python and cURL samples for both steps, so a first render is an afternoon's work, not a week's. The model itself runs on ByteDance's Dual-Branch Diffusion Transformer, which is what keeps motion and scene coherence together across a clip. Output spans 480p, 720p, 1080p and 4K, durations of 4 to 15 seconds, six aspect ratios (21:9, 16:9, 9:16, 1:1, 4:3, 3:4), fixed or dynamic camera control, and realistic human figures. Sound is a per-request toggle. Sibling endpoints cover image-to-video and reference-to-video, and fast and mini variants sit in the same catalog when you want cheaper drafts. Billing is per second of output at 80% of Flaq's listed rate: $0.096/sec at 480p, $0.192/sec at 720p, $0.48/sec at 1080p, $0.96/sec at 4K. Credits are one-time top-ups ($10, $20, $100 buys $103, $200 buys $206) on a single non-expiring balance that covers every Flaq model, so Seedream image work and Seedance video draw from the same wallet. Where it sits: Seedance 2.5 now lives on the same platform with 4-to-30-second clips, and MiniMax H3 undercuts several Seedance 2.0 configurations on price. Seedance 2.0 remains the sensible default when your clips are short, your resolution needs top out at 1080p, and you value a stable, documented endpoint over the newest model.
Behind the Verdict
Here is the honest framing: Seedance 2.0 is not the newest video model on Flaq's shelf, and Flaq will tell you so. Seedance 2.5 landed in August 2026 with 4-to-30-second clips and its own price sheet. So why pick 2.0 at all? Because most short-form work never needs the extra 15 seconds, and 2.0's cheaper tiers hold up fine at 480p and 720p where the drafts actually get made. We'd reach for this when the integration matters more than the model. The two-step pattern (submit, poll on an interval, read the URL) is boring in the best way, and the published samples mean your backend engineer is not reverse-engineering endpoints from a Discord thread. If you are comparing video APIs on cost per finished clip rather than cost per second, the 80% discount off list is the number to run. Pass when durations run long. A 20-second shot is not possible here; go to Seedance 2.5. Pass too if you need 2K or above on a budget, or if you're price-sensitive at low resolution — the MiniMax H3 comparison Flaq published in August put H3-Base at 768p and 2K with clips up to 15 seconds and lower cost than several Seedance 2.0 configurations. In practice the caveats are mundane. Every request is asynchronous, so build a real polling loop with backoff and a timeout rather than a while-true. The 5000-character prompt field and the prompt translation and optimization buttons in the playground are worth using before you burn credits — the gap between a vague prompt and a tuned one shows up directly in output quality. One balance covers image, video, 3D, music and LLM endpoints, and Flaq says it never expires. That is the quiet advantage: you can test Seedream 5.0 stills and Seedance 2.0 motion without funding two wallets. Most aggregators make you commit per-model. Here you commit once and

Real-world workflow fit
Concrete scenarios for the personas Seedance 2.0 Video AI API actually fits — and what changes day-one when you adopt it.
You need generated background footage for a product demo pipeline. You fund a $20 credit package, copy the Python submit example from the model page, set model_name to 'seedance-v2.0-text-to-video' with resolution 480p and duration 8, and poll /api/v1/video/{task_id} every 10 seconds until task_status returns 'succeed'.
Outcome: First clip URL in hand the same afternoon, with iteration costing $0.096 per second of output until the phrasing is right.
You need a batch of 9:16 vertical clips for a campaign. You tune prompts in the browser playground using its 5000-character field and prompt optimizer, enable sound, then hand the approved prompts to your developer to submit at 720p for $0.192/sec.
Outcome: A set of vertical clips with generated audio and consistent per-clip cost, sized before anything renders.
You generate several versions of the same ad using the optional seed parameter for reproducibility at 1080p, then compare cost against the 4K rate before committing to a final render.
Outcome: Reproducible variations at a known $0.48/sec, with the 4K decision priced at $0.96/sec rather than discovered on an invoice.

Models Under the Hood
as of 2026-10-16
Limitations
- The Seedance 2.0 API is asynchronous: you POST to /api/v1/video/task with model_name 'seedance-v2.0-text-to-video', receive a task_id, and poll for the result rather than getting a clip back in one call, so your integration needs a polling loop and somewhere to store the returned task_result.videos[0].url.
- Clips are capped at 15 seconds per request.
- Access is code-first through the REST endpoints and the JavaScript, Python, and cURL examples on the model page, plus a browser playground for prompt tuning — there is no timeline editor, and no offline or on-premise option is documented.
- Billing runs on prepaid Flaq credits bought as one-time packages rather than a subscription.
- Flaq's /changelog and /whats-new URLs return 404, so dated release history for this specific model is not published on those pages; product news lives on Flaq's blog instead.

Where the pricing makes sense
The company stage and team size where Seedance 2.0 Video AI API's pricing actually pencils out — and where peers do it cheaper.
Seedance 2.0 fits teams that can fund a prepaid credit balance and forecast seconds of output — the entry point is a one-time $10 package, and the $100 and $200 packages add a 3% bonus. Per second it undercuts Seedance 2.5 on the same platform (2.0 runs $0.096/sec at 480p versus 2.5 at $0.180/sec) and Kling 3.0 Turbo image-to-video at $0.1200/sec for 1080p, but sits above Wan 3.0 image-to-video at $0.1800/sec for 1080p only when you compare like resolutions.
Setup time & first value
How long it actually takes to get something useful out of Seedance 2.0 Video AI API — broken out by persona, not the marketing-page minute.
Backend developers: under an afternoon to a first rendered clip, since the model page ships working JavaScript, Python, and cURL for both the submit and poll calls and you only need an API key plus a credit top-up. Content and marketing teams: add time to tune prompts in the browser playground first, then hand off — plan a day from prompt approval to a batch of finished clips at 720p.
Switching to or from Seedance 2.0 Video AI API
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From direct ByteDance access: move your prompts to Flaq's /api/v1/video/task endpoint with model_name 'seedance-v2.0-text-to-video' and keep a single key and invoice instead of managing provider accounts.
- →From a self-hosted GPU setup: replace your inference infrastructure with the hosted endpoint and pay per second of output instead of per GPU-hour.
- →From Higgsfield AI Seedance 2.0: swap the MCP/CLI route for Flaq's REST submit-and-poll endpoints, which Flaq documents side by side with Higgsfield in its comparison write-up.
- ↗To Seedance 2.5 on the same platform: keep your Flaq key and billing, change model_name, and gain clips of 4 to 30 seconds instead of 4 to 15.
- ↗To Higgsfield AI for Seedance 2.0: move to its MCP and CLI tooling if a command-line workflow suits your team better than REST polling.
- ↗To MiniMax H3: switch generation routes if you want image-to-video at 768p and 2K, or need the open-source H3-Base weights published on Hugging Face.
