Open the billing provider customer portal

GET 
/api/v1/billing/portal

Mint a customer-portal link where the customer manages their subscription.

Changing level, updating a card, and cancelling all happen there — the billing provider owns those flows, and the resulting webhooks are what move our plan state.

• Scope required: billing:manage; role manager or above.
• 409 no_polar_customer when the org has never checked out.

400

Bad request — malformed input or failed validation.

401

Missing, expired, or invalid credentials.

403

Authenticated but not authorized for this resource. Note: cross-organization reads return 404, not 403.

404

Resource not found, or hidden for tenant-enumeration safety (the caller lacks permission to know whether the resource exists).

409

Conflict — the current resource state does not allow this operation (e.g. assessment already started, email already in use).

422

Semantic validation failure — request shape was valid but contents were not.

429

Too many requests — rate limited. Retry after the window resets.

500

Internal server error — unexpected failure.
