The Mergent API uses API keys to authenticate requests.
Authentication to the API is performed via HTTP Basic Auth. Provide your API key as the basic auth username value. You do not need to provide a password.
If you need to authenticate via bearer auth (e.g., for a cross-origin request), use -H "Authorization: Bearer yourapikey" instead of -u yourapikey.
All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
curl \
-u yourapikey:
# The colon prevents curl from asking for a password.
