Clusters Names API

openapi: 3.1.0
info:
  title: Clusters Authentication Names API
  version: '1.0'
  description: Clusters is a multichain namespace and identity service that gives users a single universal name (username/wallet) resolvable across EVM, Solana, and other blockchain ecosystems. The v1 REST API resolves addresses to cluster names and back, reads cluster profiles, checks name availability, produces registration transaction data, manages community clusters, and streams a replayable historical event feed. Read endpoints are public; write/manage endpoints require a wallet-signature bearer token. An optional API key raises rate limits.
