# Query API

The DAP Query API is a robust RESTful API that enables seamless, programmatic access to data within the Data Access Platform (DAP). Designed to handle large-scale data retrieval, it supports secure, flexible interactions with Instructure datasets.

{% hint style="info" %}
Before using they Query API, it is recommended to familiarize yourself with the [key concepts of DAP](https://developerdocs.instructure.com/services/dap/key-concepts).
{% endhint %}

### API Endpoint <a href="#api-endpoint" id="api-endpoint"></a>

The Query API can be accessed via the following endpoint:

```bash
https://api-gateway.instructure.com/dap/
```

### Conventions

The HTTP method used in an endpoint determines the type of action performed on a resource. Common methods include `GET`, `POST`, `DELETE`, and `PATCH`. Refer to the REST API reference documentation for details on the HTTP methods for each endpoint.

### Rate Limiting <a href="#api-reference" id="api-reference"></a>

DAP CLI follows the [rate limiting policies](https://developerdocs.instructure.com/services/dap/limits-policies) of DAP. Be mindful of these limits when making requests.

### Status Codes

The Query API uses standard HTTP response codes to indicate the success or failure of requests:

* Codes in the **`2xx`** range indicate success.
* Codes in the **`4xx`** range indicate incorrect or incomplete parameters (e.g. invalid authentication credentials, non-exist namespace etc.).
* Codes in the **`5xx`** range indicate a server-side issue (e.g. gateway timeout error, restricted client access etc.).
