Envio GraphQL API

The Envio HyperIndex GraphQL API exposes indexed smart contract events and blockchain state from any EVM-compatible chain. Each HyperIndex deployment auto-generates a GraphQL API based on the user-defined `schema.graphql` entities, backed by a Hasura engine. The API supports queries, subscriptions (via WebSockets), filtering, sorting, and pagination over indexed on-chain data. Built-in system types provide indexing progress and metadata alongside user-defined entity types.
