Tabtab has launched a unified API gateway that consolidates access to 16 distinct AI models, specifically 11 image generators and 5 video synthesis engines. The architecture rejects synchronous request-response patterns in favor of an asynchronous Task API, forcing developers to create a task, receive a unique ID, and poll for completion. This design choice directly addresses the latency inherent in video generation, where jobs take seconds to render and callbacks remain unreliable for production-grade reliability.

The Async Task Architecture

Developers interact with the base URL https://api.tabtabapi.com using Bearer authentication keys prefixed with sk_. The workflow begins with a POST request to /api/task/create, passing the model identifier (such as seedance-2.5) and arguments like prompts. The API immediately returns a task ID rather than a media file. Subsequent status checks require GET requests to /api/task/status?task_id=, which must be polled in a loop with explicit timeouts until the status transitions to succeeded or failed. This pattern mitigates the risk of relying solely on callback URLs, which the documentation notes are not guaranteed.

Pricing and Model Specifics

The platform operates on a pay-as-you-go basis with top-ups starting at $2, offering a special group rate at 0.80x. As of October 31, 2026, Seedance 2.5 costs $0.20 per second at 720p resolution, making a 10-second clip $2.00. Kling 4.0 is significantly cheaper at $0.09 per second for the same duration and resolution. For image models, GPT Image 2.5 starts at $0.006 per image at 1K resolution, while Seedream 5 Pro and Nano Banana 2.1 are priced at $0.02 and $0.015 per image, respectively. Local file inputs must be uploaded via /api/task/materials, limited to 50 MiB per file and 20 uploads per minute per key.

Key Takeaways

  • The API enforces an async workflow: create task, poll status, download result. Synchronous returns are not supported.
  • Video jobs are priced per second; a 10-second 720p clip on Seedance 2.5 costs $2.00, while Kling 4.0 costs $0.90.
  • Result files expire after download availability, requiring prompt retrieval to avoid data loss.
  • No free tier is offered, and the platform does not claim specific uptime or latency metrics, focusing instead on transparent pricing and documented polling.

The Bottom Line

Tabtab’s rigid async pattern is a pragmatic trade-off for unifying a fragmented model landscape, but the lack of guaranteed callbacks and expiring files demands robust client-side error handling and immediate result ingestion.
