# Entities

### Entity management endpoints

Entities are basic building blocks of a graph. They can be automatically extracted from a document and then added to a graph.

To manage entities extracted from a document, you can use the following endpoints:

| Method | Endpoint | Description |
| - | - | - |
| GET | [/documents/\{id}/entities](https://io-migration.mintlify.site/reference/get-extracted-entities.md) | List *Entities* identified within a document. |

Once entities are added to a graph by a POST to “/graphs/\{id}/\{object\_type}” endpoint, you can manage them using the following endpoints:

| Method | Endpoint | Description |
| - | - | - |
| GET | [/graphs/\{collection\_id}/entities](https://io-migration.mintlify.site/reference/list-graph-entities.md) | List entities (/\[r2r-docs.sciphi.ai]/\[1]) |
| POST | [/graphs/\{collection\_id}/entities](https://io-migration.mintlify.site/reference/add-new-entities.md) | Create entity |
| GET | [/graphs/\{collection\_id}/entities/\{entity\_id}](https://io-migration.mintlify.site/reference/get-single-entity-details.md) | Get entity details |
