# NEXUS AI Billing

Billing is an authenticated organization-level platform feature separate from deployment operations.

## Operations

Authorized organization users can inspect subscription status, start a trial where eligible, create a checkout or customer-portal session, change or cancel a subscription, and list or retrieve invoices. Healthcare checkout uses a separate route.

Billing routes require NEXUS authentication and the appropriate organization billing permission. Payment-provider webhooks are handled by the platform and are not an agent-facing endpoint.

## Safety

Subscription changes, checkout, and cancellation have financial consequences. Require explicit authorization and do not place payment details or billing tokens in agent prompts or logs.
