About the Vidu Q4 API

How much does the Vidu Q4 API cost?

Vidu Q4 costs from $0.05 per second of video on Revana (540p: $0.05; 720p: $0.10; 1080p: $0.12; 2K: $0.19; 4K: $0.39). You pay in prepaid credits, 100 credits to the dollar, with no subscription or monthly minimum. A generation that fails costs nothing.

How do I call Vidu Q4 from code?

Send POST https://api.revana.si/v1/generations with {"model": "vidu-q4", "input": {...}} and your Revana API key as a Bearer token, poll GET /v1/generations/{id} until it succeeds, then download GET /v1/generations/{id}/content. Every model on Revana takes the same request shape.

What happens if a Vidu Q4 generation fails?

You are charged once, only for the route that delivers. A failed generation costs $0.00.

What can Vidu Q4 do on Revana?

Vidu Q4 supports image to video and reference to video, resolutions 540p, 720p, 1080p, 2K, 4K and silent output. A value it does not offer is refused with 422 before anything is charged.

Can my AI agent use Vidu Q4?

Yes. Connect the Revana MCP server (https://revana.si/api/mcp) to Claude, ChatGPT, Cursor or Codex, or have the agent call the REST API. The agent can list models, get a free quote and generate on your credits.
