What problem does it solve?
The indexer GraphQL API centralizes access to on-chain state, real-time events, and wallet session management so developers can reliably query blocks, transactions, contract actions, and shielded/unshielded activity without building custom indexer infrastructure.
Core Features & Use Cases
- HTTP query and mutation endpoint for fetching blocks, transactions, contractAction records, and wallet connect/disconnect flows.
- WebSocket subscriptions (graphql-transport-ws) for blocks, contractActions, shieldedTransactions, unshieldedTransactions, dustLedgerEvents, and zswapLedgerEvents with offset-based resumption.
- Practical guidance: endpoint URLs for local/preview/preprod, query limits (max complexity 200, max depth 15, 1 MiB body), GraphQL type definitions, error handling patterns, and example HTTP and TypeScript subscription flows for building DApps and monitoring contracts.
Quick Start
Send a GraphQL POST to /api/v4/graphql to fetch the latest block and open a websocket to /api/v4/graphql/ws to subscribe to contract actions.
