Classify a batch inline
Send up to 300 rows and get every label back in the same response. Runs on the realtime engine (realtime rate), with internal concurrency so it returns in seconds. Each row carries its own id (echoed back) and one or many model names. Naming a model that doesn't exist fails the whole request with 404; a row that fails validation comes back with error while the others return.
