Create Batch from Rows

The application/json form of POST /v2/batch, the same endpoint as “Create Batch”: send the records in a rows array instead of a JSONL file. Each row is the same object as one JSONL line and is validated the same way: 20-500 rows by default, 5 MB or smaller when serialized as JSONL, unique request_id values, and endpoint exactly /v2/generate. Errors name a refused row by its line, where line N is rows[N-1]: dialogue edit refusals return it as lineNumber, other record errors only in message. Requires the Scale plan or higher. In early access, enabled per organization, a row’s payload can carry dialogueEdit to render a completed preview from POST /v2/dialogue-edits: send one video input, the video the preview was made from, and no audio input. All dialogue edit rows in a batch must come from the same source video. Each row is expanded at submit into the request POST /v2/generate builds for that preview and is charged the same. A dialogue edit row that cannot be rendered refuses the whole batch with the /v2/generate errorCode (for example dialogue_edit_not_found, 422) and lineNumber. See Batch Processing.
