Check DLCs

POST

https://api.lootlocker.com/game/dlcs/v1/check

Reconciles the player's platform-owned DLCs and returns the DLCs they currently hold.

Ownership is verified server-side against the player's linked platform account (Meta or Steam); the client cannot grant itself DLCs. Missing DLCs are granted and DLCs the player no longer owns are revoked. The player and game are taken from the session token, so a caller can only ever reconcile and read their own DLCs.

Reconciliation is serialized per player. If another reconciliation for the same player is already in flight this endpoint does not reconcile and returns the player's current DLC list as-is, which may be slightly stale. Call it again shortly afterwards for an up-to-date list.

Only Meta and Steam accounts support DLC checks. If the player has no linked account for the session's platform, or the platform is not supported, the request is rejected with 400.
