You can view and manage your API keys in the platform UI. Your API keys carry many privileges, so be sure to keep them secure! Provide your API key as the `Authorization` header. The value of the header consists of `Bearer` prefix and secret key generated through the platform UI. ```bash curl -X GET 'https://api.chainstack.com/v1/organization/' \ --header 'Authorization: Bearer FX7CWlLg.FMpAO8cgCX2N7s41EncRru2nb5CmTZUt' ``` All API requests must be made over HTTPS. ````
