Metadata Repository Service provides developers with an API-driven repository service that specialises in storing and hosting metadata in JSON format made available through a publicly available URL.

Managing and hosting metadata for thousands of assets can be a hassle for developers.

Metadata Repository Service is a tool that helps facilitate some of the challenges and supports the following use cases:

  • Store and host metadata made publicly available via a URL
  • Reference different metadata types where it could be linked or embedded
  • Create metadata in an unpublished state, then pick one at random at the point of minting
  • View historical data for a given asset metadata

​
Requesting Namespace

To start using the Metadata Repository Service, you’ll need a namespace. You can request one by reaching out to the Futureverse support team, who will provide a namespace specific to your project.

Authentication

The Metadata Repository Service uses Sign In with Ethereum (SIWE) to authenticate users. This generates access tokens that are required for interacting with the authenticated endpoints.

Tip: Use the SIWE Generator Tool to create your tokens. The generated content in the Authorization box, after you sign, should be used as the Authorization header of your API calls.
