Prediction Flow

1. Check model GET https://api.eachlabs.ai/​v1/​model?slug=<slug> — validates the model exists and returns the request_schema with exact input parameters. Always do this before creating a prediction to ensure correct inputs.
2. POST https://api.eachlabs.ai/​v1/​prediction with model slug, version "0.0.1", and input matching the schema
3. Poll GET https://api.eachlabs.ai/​v1/​prediction/​{id} until status is "success" or "failed"
4. Extract the output video URL from the response
