# Billing Subscription Cancel

`POST /api/billing/subscription/cancel`

Cancel renewal — claude/codex-style "stop my subscription".

No money moves: the current period continues working until
`expires_at`, at which point the hourly `expire_due_subscriptions`
cron demotes the user to community as it would have anyway. The
behavior change is purely UI:
  - `cancelled_at` gets a timestamp so the SPA can render the
    cancelled state ("已取消，<date> 到期后变为 Free") instead of
    the open-ended "active".
  - `auto_renew` is flipped FALSE for future-proofing (a hosted
    WeChat Pay 协议支付 / Alipay 周期扣款 product would gate on
    this).

Idempotent — cancelling a sub that is already cancelled is a
no-op and returns the same payload.
