# Server

Faceplugin Face Recognition Server SDK and Face Recognition API. On-premise HTTP for Windows, Linux Docker, and .NET. detect, match, similarity on port 8083. Offline after license activation.

Face **Recognition** as an HTTP API (or .NET bindings) on **your** machine. Still-image detect, quality, template extract, 1:1 match, and template similarity. There is **no** server-side 1:N gallery (`POST /api/identify` does not exist).

Typical call order: `GET /api/machinecode` → send machine code → `POST /api/activate` → `POST /api/detect` / `match` / `similarity`. Default port **8083**.

For recognition **and** liveness in one process, see [Recognition + Liveness](/products/face-recognition-sdk/recognition-and-liveness.md). For on-device apps, use [Mobile SDK](/products/face-recognition-sdk/recognition-and-liveness/mobile-sdk.md). Open-source Python samples: [Open Source](/products/face-recognition-sdk/recognition/open-source-windows-and-linux.md).

### FAQ

**Is this a Face Recognition API?** Yes. HTTP on port **8083**: `POST /api/detect`, `/api/match`, `/api/similarity`.

**Is there server-side 1:N?** No. There is no `POST /api/identify` gallery. Store templates in **your** database.

**Docker vs Windows?** Same routes. Windows has no Docker; Linux uses `faceplugin/face-recognition`.

**Recognition + liveness in one process?** See [Recognition + Liveness](/products/face-recognition-sdk/recognition-and-liveness.md). Or keep Face Liveness on **8084** as a separate product.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.faceplugin.com/products/face-recognition-sdk/recognition/server-sdk.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
