One API key for 20 AI video models: real pricing, working code, and a $1 free tier

Описание и применение

Объединенный API Viddra упрощает интеграцию 20+ моделей видео‑ИИ, обеспечивая единый ключ, единый формат запросов и оплату по секундам, что снижает сложность разработки и управление затратами.

Задача

Developers face fragmented SDKs, auth schemes, billing, and polling loops when using multiple AI video providers, complicating integration and cost management.

Результат

Unified API reduces integration complexity, standardizes billing, and enables cost-aware routing across multiple AI video models.

Рабочий процесс

• 1. Sign up for Viddra and obtain API key (includes $1 free credit).
• 2. Set the key in environment variable VIDDRA_API_KEY.
• 3. Send a POST request to https://api.viddra.com/v1/video/generations with JSON body containing model, prompt, and duration.
• 4. Receive 202 Accepted and a task_id.
• 5. Poll the task status every 10 seconds using GET https://api.viddra.com/v1/video/generations/{task_id} until status is succeeded or failed.
• 6. On success, retrieve video_url; on failure, error is returned and cost is refunded automatically.
• 7. Optionally switch the model field to route by price/quality (e.g., kling3.0, wan3.0-video, hailuo-h3).

Доказательства

One endpoint handles every model. Auth is a standard bearer key:

Billing works on hold-then-settle: the estimated cost is held when the task starts, and on failure the hold is refunded automatically

$1 free credit on signup — enough to test 5–8 real generations across models, no card required
