# Billing Subscriptions

`GET /api/billing/subscriptions`

Every currently-active subscription, ONE per research domain
(omics, humanities_social, ...), each with its own expires_at /
auto_renew / cancelled_at.

This is the per-domain source of truth for the client's on-app-open
expiry reminder: the flat `domain_plans` token claim carries only the
tier, and `/api/auth/plan_token`'s expires_at is the 24h token TTL —
neither reflects the actual membership expiry.

## Headers

- `authorization` string, nullable

## Response `200`

Successful Response

- object

## Other responses

- `422` — Validation Error
