# AI Extraction & Knowledge Graph

> Use AI Extraction and Knowledge Graph APIs to process content and build graph data.

DataGOL exposes **AI Extraction** and **Knowledge Graph** APIs so you can extract structured data from documents and manage knowledge graphs in your workspace.

**Where to find them:** Open the **API Reference** tab (top navigation). In the left sidebar you’ll see groups **AI Extraction** and **Knowledge Graph** — expand those to see and try each endpoint.

## AI Extraction APIs

Base path: `https://be.datagol.ai/noCo/api/v2/workspaces/{workspaceId}/...`

| Method | Endpoint                                                                                            | Summary                                 |
| ------ | --------------------------------------------------------------------------------------------------- | --------------------------------------- |
| POST   | `/noCo/api/v2/workspaces/{workspaceId}/extraction/schema/generate`                                  | Generate Schema for Advanced Extraction |
| POST   | `/noCo/api/v2/workspaces/{workspaceId}/extraction/advanced/test`                                    | Test API for Advanced Extraction        |
| POST   | `/noCo/api/v2/workspaces/{workspaceId}/extraction`                                                  | Create Extraction                       |
| PUT    | `/noCo/api/v2/workspaces/{workspaceId}/extraction/{extraction_id}`                                  | Update Extraction                       |
| DELETE | `/noCo/api/v2/workspaces/{workspaceId}/extraction/{extractionId}`                                   | Delete Extraction                       |
| GET    | `/noCo/api/v2/workspaces/{workspace_id}/extraction/{element_type}/{element_id}`                     | Get Extractions                         |
| POST   | `/noCo/api/v2/workspaces/{workspace_id}/extraction/{extraction_id}/{element_type}/{element_id}/run` | Trigger Extraction                      |
| GET    | `/noCo/api/v1/requestLog/status/{request_id}`                                                       | Poll Status                             |

## Knowledge Graph APIs

Base path: `https://be.datagol.ai/ai/api/v2/knowledge-graph...`

| Method | Endpoint                            | Summary                    |
| ------ | ----------------------------------- | -------------------------- |
| POST   | `/ai/api/v2/knowledge-graph/create` | Create Knowledge Graph     |
| GET    | `/ai/api/v2/knowledge-graph/status` | Get Knowledge Graph Status |
| GET    | `/ai/api/v2/knowledge-graph`        | Get Knowledge Graph        |

## AI Extraction (overview)

AI Extraction lets you define schemas and run extraction jobs on workspace content (files, folders): schema generation from prompts, advanced extraction with custom schemas, and create/update/delete extraction configs. Use **Trigger Extraction** to run and **Poll Status** to check progress.

## Knowledge Graph (overview)

Knowledge Graph APIs let you create and query knowledge graphs: **Create Knowledge Graph** to start a job, **Get Knowledge Graph Status** to check status, and **Get Knowledge Graph** to retrieve the graph.

## Authentication

All AI Extraction and Knowledge Graph endpoints use the **x-auth-token** header (workbook/workspace API). Include your workspace token in each request.

## Next steps

Go to the **API Reference** tab and expand **AI Extraction** or **Knowledge Graph** to see request parameters, bodies, and responses for each endpoint.
