Genbase AI Video Generation

Generate AI videos and images via Genbase's x402-enabled platform. Supports multiple generation models including OpenAI Sora 2 for high-quality video, xAI Grok Imagine for fast and flexible video, and GPT Image for AI image generation. Through the Polymer Pay proxy, each generation is paid individually — no Genbase account or API key required.

Authentication

All requests route through the Polymer Pay proxy. Include your Polymer Pay API key in every request:

{
  "headers": {
    "Content-Type": "application/json",
    "x-polymer-pay-api-key": "{{POLYMER_PAY_API_KEY}}"
  }
}

Base URL: https://pay.polymerlabs.org/proxy/https/www.genbase.fun

To get an Polymer Pay API key, sign up at https://my.pay.polymerlabs.org/dashboard/api-keys.

When to Use

• High-quality video — Use Sora 2 for cinematic, high-fidelity video generation when quality matters most ($0.20 per video).
• Fast and flexible video — Use xAI Grok Imagine for quicker generation with flexible duration (1-15 seconds) and multiple input modes at $0.01/sec.
• Image-to-video — Use xAI with mode: "image-to-video" and a reference image URL to animate a still image.
• Quick image generation — Use GPT Image for fast, affordable AI image generation at $0.02 per image.
• Budget-conscious video — xAI at $0.01/sec for a 5-second video ($0.05) is significantly cheaper than Sora 2 ($0.20) when maximum quality is not required.

Best Practices

• Poll for completion — Video generation is asynchronous. After submitting a request, poll the corresponding query endpoint every 15-30 seconds until the status is Ready or completed.
• Use Sora 2 for quality, xAI for speed — Sora 2 produces higher-quality output but takes 3-15 minutes. xAI generates in 2-5 minutes and is cheaper for shorter clips.
• Start with short durations — Use 10-second Sora 2 videos or short xAI clips to validate your prompt before generating longer content.
• Write cinematic prompts — Include camera movements (drone shot, tracking shot), lighting (golden hour, cinematic), and specific visual details for the best results.
• Mind content policy — Sora 2 enforces OpenAI's content policy. Prompts with violence or adult content will cause generation failure. Contact [e-mail] with video_id and wallet address for refunds on policy failures.
• Choose the right resolution — For Sora 2, use 1280x720 for landscape, 720x1280 for portrait/vertical content, 1792x1024 for widescreen, and 1024x1792 for tall formats.
