In this request, replace YOUR_API_KEY with your actual API key and specify the desired date range.

Step 3: Processing API Responses

The API response will include a JSON object containing the requested time-series data. Below is an example of a typical response:

{
"success": true,
"timeseries": true,
"start_date": "2026-05-01",
"end_date": "2026-05-10",
