$curl = curl_init();

curl_setopt_array($curl, array(
    CURLOPT_URL => 'https://eodhd.com/api/historical-market-cap/AAPL.US?api_token=demo&fmt=json',

curl_close($curl);

try {
    $data = json_decode($data, true, 512, JSON_THROW_ON_ERROR);
    var_dump($data);
} catch (Exception $e) {
    echo 'Error. '.$e->getMessage();
}

import requests

url = f'https://eodhd.com/api/historical-market-cap/AAPL.US?api_token=demo&fmt=json'
data = requests.get(url).json()

print(data)

library(httr)

response <- GET(url)

if (http_type(response) == "application/json") {
    content <- content(response, "text", encoding = "UTF-8")
    cat(content)

    cat("Error while receiving data\n")

AAPL.US is the ticker code and it consists of two parts: {SYMBOL_NAME}.{EXCHANGE_ID}, you can use a US ticker code with or without the exchange part (AAPL or AAPL.US).
api_token – your own API KEY, which you will get after you subscribe to our services.
from and to – the format is ‘YYYY-MM-DD’. If you need data from Jan 5, 2020, to Feb 10, 2020, you should use from=2020-01-05 and to=2020-02-10.
