# Billing App Store Sync

`POST /api/billing/app-store/sync`

## Request

- Base URL: `https://writer.swapp1990.org` (the document declares no server; this is the origin it was published from)
- URL: `https://writer.swapp1990.org/api/billing/app-store/sync`
- Auth: none declared

Re-read RevenueCat for the signed-in iOS user and return their tier.

The client may send its current RevenueCat customerInfo as diagnostic
context, but the server does not trust it for access or identity:
mcp-core looks up the signed-in account's own RevenueCat id (the Logto
subject) with the server-side secret and stores ``store_subscription``.

## Response `200`

Successful Response

- unknown
