# Gliner2 Async

`POST /v1/gliner-2/async`

## Request

- Base URL: `https://api.fastino.ai`
- URL: `https://api.fastino.ai/v1/gliner-2/async`
- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer
- TypeScript: <https://skmtc.dev/fastino-ai/apis/pioneer-inference-api/docs/v1/gliner-2/async/post.ts> (a function with typed inputs; its response is checked against the schema)

Submit large GLiNER-2 request for async processing.

Use this endpoint when processing >1M tokens that would exceed the 30-second
timeout. Returns immediately with a job_id; poll GET /gliner-2/jobs/{job_id}.
With Zero Data Retention, the text is never stored and the result is deleted on
its first read, or 24 hours after the job finishes if it is never read.

## Request body

- AsyncGlinerRequest: Request for async GLiNER-2 processing.
  - `format_results` boolean, nullable
  - `include_confidence` boolean, nullable
  - `include_spans` boolean, nullable
  - `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
  - `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[]
  - `threshold` number, nullable
