description: 'The domain-management and usage API for RB2B OEM partners embedding RB2B identification
  inside their own platforms — POST /add_domain, POST /delete_domain, GET /domains and GET /credit_usage,
  authenticated with an Api-Key header issued on the OEM dashboard. The API is the ONLY supported way
  to authorize a domain: RB2B ignores traffic from any domain not added here, even when the OEM tracking
  script is installed. Credit usage returns credits_used with the last and next billing dates.'
