### Make an API Request with Python

Source: https://guide.data.gov.sg/developer-guide/api-overview/how-to-use-your-api-key.md

This Python script demonstrates how to set the `x-api-key` header for an API request and print the JSON response.

```python
import requests

headers = {"x-api-key": "YOUR_API_KEY"}
response = requests.get("https://api-production.data.gov.sg/v2/public/api/collections", headers=headers)
print(response.json())

### Initiate Dataset Download

Source: https://guide.data.gov.sg/developer-guide/dataset-apis/download-dataset.md

Initiates the download process for a specified dataset. This API can also accept optional filters for columns and rows to retrieve a subset of the dataset.

```APIDOC
## GET /v1/public/api/datasets/{datasetId}/initiate-download

### Description
Initiate download for a dataset. This endpoint is used to start the download process for a given dataset ID. It supports optional filtering of columns and rows.

### Method
GET

### Endpoint
/v1/public/api/datasets/{datasetId}/initiate-download

### Parameters
#### Path Parameters
- **datasetId** (string) - Required - ID of the dataset

#### Request Body
- **columnNames** (array[string]) - Optional - List of selected columns in filtered dataset.
- **filters** (array[object]) - Optional - Filters define how users want to filter their dataset. Filters is an array of objects which have `columnName`, `type` and `value` attributes.
  - `columnName` (string) - The column where the filter is to be applied.
  - `type` (string) - Can be `EQ`, `LIKE`, or `ILIKE`:
    - **EQ**: Direct comparison for filter and is case sensitive.
    - **LIKE**: Similar to EQ but includes partial matching. Any words containing the string in the `value` attribute will be matched.
    - **ILIKE**: Case-insensitive version of LIKE.

### Request Example
```json
{
  "columnNames": [
    "column1",
    "column2"
  ],
  "filters": [
    {
      "columnName": "status",
      "type": "EQ",
      "value": "active"
    }
  ]
}
```

### Response
#### Success Response (201)
- **code** (integer) - Response code
- **data** (object) - Contains the message of the response.
  - **message** (string) - Success message
- **errorMsg** (string) - Error message (if any)

#### Response Example
```json
{
  "code": 200,
  "data": {
    "message": "Download initiated successfully."
  },
  "errorMsg": null
}
```

#### Error Response (400)
- **code** (integer) - Response code
- **name** (string) - Error type
- **errorMsg** (string) - Error Message

#### Error Response (429)
- **code** (number)
- **name** (string)
- **data** (object)
- **errorMsg** (string) - Rate limit exceeded
```
