A new generation of the Batch API is available, improving flexibility while also improving security and throughput.
Uploads move from one-file-at-a-time batch inputs to multi-file **upload sessions** with MD5 integrity checks.
Batch executions follow that move, allowing multi-file inputs that now support Parquet extensions, deprecate JSONL and keep the support for CSV for low complexity schemas.

- `POST /v2/api/files/upload` — request upload URLs for one or more files.
- `GET /v2/api/files` — list uploaded files and their metadata.
- `POST /v2/api/batches` — start a batch prediction for one or more files.
- `GET /v2/api/batches/{id}/result` — retrieve a download URL or a URI path to access your results.

The v1 batch and batch-inputs endpoints are now **deprecated**, they remain available for backward compatibility and will be sunset soon.
