GET https://api.indices-api.com/latest?access_key=YOUR_API_KEY&symbols=CAC40
In this request, replace YOUR_API_KEY with your actual API key obtained from the Indices-API. The response will provide you with the latest exchange rates for the CAC 40 along with other indices.
Example API Response
Here’s an example of a successful response from the Latest Rates endpoint:
{
"success": true,

"base": "USD",
"date": "2025-10-25",
"rates": {
"CAC 40": 0.00137,
"DOW": 0.00029,
"NASDAQ": 0.00039,
