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  • Create metadata in an unpublished state, then pick one at random at the point of minting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.

​
Metadata Domain

You can explore the full details of the endpoint and other available API operations using the Swagger documentation for Production or Staging environments.

​
Production

​
Staging

​
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.
