Futureverse Asset Register API
Relay-compliant GraphQL API for the Asset Register — a metadata ledger that defines what an asset is, what it can do, and which environments it works in, across chains and for off-chain assets. 29 queries cover assets, asset trees, collections, token schemas, namespaces, accounts, owners, transactions and webhook subscriptions; 28 mutations cover schema registration, asset linking, off-chain asset registration, profiles and webhook management. Introspection is open and anonymous; writes require a Sign-In-With-Ethereum bearer token or a wallet-signed ARTM transaction.
