Use cURL

The examples in this document use cURL to demonstrate how to access the REST API for AI Services.

Task 1: Install cURL

To connect securely to the server, you must install a version of cURL that supports SSL and provide an SSL certificate authority (CA) certificate file or bundle to authenticate against the CA certificate store, such as Verisign.

To install cURL on a Windows 64-bit system:

  1. In your browser, navigate to the cURL Releases and Downloads page at https://curl.se/download.html.

  2. Locate the version of the cURL software that corresponds to your operating system, click the link to download the ZIP file, and then install the software.

  3. Go to the cURL CA Certs page at https://curl.se/docs/caextract.html and then download the ca-bundle.pem SSL CA certificate bundle to the folder in which you installed cURL.

Task 2: Set Environment Variable for cURL

Set the CURL_CA_BUNDLE environment variable to the location of your local CA certificate bundle. For example, you can set the environment variable in a command window using the following command:

set CURL_CA_BUNDLE=ca-bundle.pem

For information about CA certificate verification using cURL, see https://curl.se/docs/sslcerts.html.
