Request an access token by specifying your x-client-id and x-api-key in the HTTP request header. The token returned is required for calling all other API endpoints, which HTTP header must include x-auth-token: <YOUR_TOKEN_HERE>.
The access token is valid for 30 minutes and can be used multiple times for all other API endpoints until it expires. It’s recommended to rely on expired_at for the accurate token expiration time. This API enforces a rate limit of 50 requests per minute.
