We are pleased to announce the latest updates to the MSU Open API, including new endpoints and enhancements to existing APIs.

:play_button: API Updates

[Item]

The item list endpoints have been updated to resolve an issue where items were always filtered to show only enhanceable items by default. A new isEnhanceable query parameter has been added, allowing builders to filter explicitly.

  • Updated Endpoints
    • GET /v1rc1/accounts/{walletAddress}/items — Added isEnhanceable query parameter
    • GET /v1rc1/characters/{assetKey}/items — Added isEnhanceable query parameter

[Market]

Search filters can now be applied on the following endpoints regardless of authentication status.

  • Updated Endpoints
    • GET /v1rc1/search/characters
    • GET /v1rc1/search/items
    • GET /v1rc1/search/nicknames

[GameMeta]

A new endpoint has been added to retrieve job classification data, including job and class codes and their category tiers. Access to this endpoint requires a permission request — see “How to Apply for Access” below.

  • New Endpoints
    • GET /v1rc1/gamemeta/jobs/classifications — Retrieve job classification data

For detailed specifications, request and response examples, and integration guides, please refer to the updated MSU OpenAPI Docs.
