Example 1: Get EURUSD price

main.c

#include <stdio.h>
#include <curl/curl.h>

int main() {
        CURL *hnd = curl_easy_init();

        curl_easy_setopt(hnd, CURLOPT_CUSTOMREQUEST, "GET");
        curl_easy_setopt(hnd, CURLOPT_URL, "http://192.168.8.177:81/v1/quote?symbol=EURUSD");

        struct curl_slist *headers = NULL;
        headers = curl_slist_append(headers, "Accept: application/json");
        curl_easy_setopt(hnd, CURLOPT_HTTPHEADER, headers);

        CURLcode ret = curl_easy_perform(hnd);
}

    }
}

// Función para la parte HTTP POST con libcurl
void http_post() {

    struct curl_slist *headers = NULL;
    headers = curl_slist_append(headers, "Content-Type: application/json");
    headers = curl_slist_append(headers, "Accept: application/json");
    curl_easy_setopt(hnd, CURLOPT_HTTPHEADER, headers);

    CURLcode ret = curl_easy_perform(hnd);

    // Limpieza
    curl_easy_cleanup(hnd);
    curl_slist_free_all(headers);
}

int main() {
    curl_global_init(CURL_GLOBAL_ALL);  // Inicialización global de libcurl

    http_post();        // Primero hace el POST
    websocket_part();   // Luego conecta el WebSocket

    curl_global_cleanup();
    return 0;
