API to Check Valorant Account Value (Querying Riot Games API)

We are currently expanding our internal asset aggregation dashboard to include Riot Games titles. When attempting to query the Valorant API endpoints to programmatically check Valorant inventory value and retrieve weapon skin schemas, we are encountering an issue where the authentication succeeds, but the JSON payload for the user's inventory metadata is returning as completely full.

We are using the standard OAuth flow with the correct scopes, and the bearer token validates fine against other endpoints. However, when trying to login through the <Link removed by mod> to manually verify the item data using the same account, the UI also renders a blank state for the locker, despite the assets being fully accessible and usable in the game client.

Has anyone implemented a custom integration to extract skin metadata (e.g., chromas, VP costs) via the official API? Any insight into whether this is a known API limitation when trying to check Valorant account worth and retrieve digital asset inventory values would be highly appreciated.
