The reason you received no response is due to three common issues when running an OpenRouter multimedia script directly inside a local browser file:
1. Incorrect Headers/HTTP Referer: OpenRouter requires an HTTP-Referer or X-Title header for browser-based requests to identify the app, or it silently blocks it.
2. Incorrect Model Names: The models must exactly match OpenRouter's production slugs (e.g., google/gemini-2.5-flash or stabilityai/stable-diffusion-xl for images, and google/veo-3.1 or bytedance/seedance-2.5 for videos).
3. Improper Video Polling URL: The exact video endpoint path has specific requirements for pulling results. [1, 2, 3]
Here is the fully fixed, single-file HTML code. It includes proper request payloads, required fallback headers, and robust error trapping to output the exact reason a request fails (e.g., "Insufficient Credits" or "Invalid Key") right on the screen. [4]
