About the Veo 3.1 API

How much does the Veo 3.1 API cost?

Veo 3.1 costs from $0.20 per second of video on Revana (720p: $0.20; 720p + with audio: $0.40; 1080p: $0.20; 1080p + with audio: $0.40; 4K: $0.40; 4K + with audio: $0.60). 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 Veo 3.1 from code?

Send POST https://api.revana.si/v1/generations with {"model": "veo-3.1", "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 Veo 3.1 generation fails?

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

What can Veo 3.1 do on Revana?

Veo 3.1 supports text to video, image to video and first + last frame, resolutions 720p, 1080p, 4K, durations 4 s, 6 s, 8 s, aspect ratios 16:9, 9:16 and generated audio. A value it does not offer is refused with 422 before anything is charged.

Can my AI agent use Veo 3.1?

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.
