## Request body

- AsyncGlinerRequest: Request for async GLiNER-2 processing.
  - `task` string, nullable: **Deprecated** legacy task hint. One of: 'extract_entities', 'classify_text', 'extract_json', 'schema'. Omit for the unified GLiNER2 path. Submitting a legacy task value still succeeds but the response carries ``Deprecation: true`` and a ``Sunset`` header.
  - `text` union, required
    - string
    - string[]
  - `schema` union, required: Extraction schema. The flat ``list[str]`` of entity labels is deprecated; use the unified dict shape (``entities`` / ``classifications`` / ``structures`` / ``relations``) for forward compatibility. Deprecated submissions emit ``Deprecation: true`` and ``Sunset: <RFC 7231 date>`` headers.
    - string[]
    - object
  - `threshold` number, nullable
  - `include_confidence` boolean, nullable
  - `include_spans` boolean, nullable
