Example prompt: Can you remove the green screen background from this image and give me back the subject with a transparent background? Here's the base64-encoded image data.

## When to prefer this

Choose this endpoint when you need automated chroma key / green screen removal as a simple API call without setting up local video editing software. Ideal for agent workflows that process media assets at scale, especially when integrating background removal into automated content pipelines.

## Known failure modes

- No green screen detected in the provided media — returns error or unmodified output
- Invalid or malformed base64 data string causes processing failure
- Image too large or unsupported format results in rejection
- Poor green screen quality (shadows, spill, uneven lighting) may produce imperfect keying
- Missing or empty data field returns validation error
