# Get single entities
|
|
|
|
|
|
|
|
|
|
This is a guide on how to retrieve detailed information on a single entity using the OpenAIRE Graph API.
|
|
|
|
|
|
|
|
|
|
## Endpoints
|
|
|
|
|
Currently, the Graph API supports the following entity types:
|
|
|
|
|
|
|
|
|
|
- Research products - endpoint: `GET /researchProducts/{id}`
|
|
|
|
|
- Organizations - endpoint: `GET /organizations/{id}`
|
|
|
|
|
- Data sources - endpoint: `GET /dataSources/{id}`
|
|
|
|
|
- Projects - endpoint: `GET /projects/{id}`
|
|
|
|
|
|
|
|
|
|
It is evident that you can retrieve the data of a single entity by providing the entity's unique OpenAIRE identifier (id) in the corresponding endpoint.
|
|
|
|
|
You can find more details about OpenAIRE identifiers [here](../../data-model/pids-and-identifiers).
|
|
|
|
|
|
|
|
|
|
## Response
|
|
|
|
|
The response of the Graph API is a [Research Product](../../data-model/entities/research-product), [Organization](../../data-model/entities/organization), [Data Source](../../data-model/entities/data-source), or [Project](../../data-model/entities/project), depending on the endpoint used.
|
|
|
|
|
|
|
|
|
|
## Examples
|
|
|
|
|
Here are some examples of how to retrieve single entity records using the Graph API. Please, navigate through the tabs to see the examples for each entity type.

"Analyzing political conservatism as motivated social cognition integrates theories of personality (authoritarianism, dogmatism-intolerance of ambiguity), epistemic and existential needs (for closure, regulatory focus, terror management), and ideological rationalization (social dominance, system justification). A meta-analysis (88 samples, 12 countries, 22,818 cases) confirms that several psychological variables predict political conservatism: death anxiety (weighted mean r = .50); system instability (.47); dogmatism-intolerance of ambiguity (.34); openness to experience (-.32); uncertainty tolerance (-.27); needs for order, structure, and closure (.26); integrative complexity (-.20); fear of threat and loss (.18); and self-esteem (-.09). The core ideology of conservatism stresses resistance to change and justification of inequality and is motivated by needs that vary situationally and dispositionally to manage uncertainty and threat."
