What is the Bitquery Arbitrum API?
It's a GraphQL interface over curated, indexed Arbitrum data. Write powerful queries instead of building and maintaining your own indexer for the fastest L2 solution.
What can you build with it?
Track GMX perpetual positions, monitor DEX liquidity and trading volumes, analyze cross-chain bridge flows, stream smart contract events, compute trading KPIs, and power real-time dashboards for the most active L2 ecosystem.
How is it different from raw Arbitrum RPC?
| Feature | Arbitrum RPC | Bitquery Arbitrum API |
|---|---|---|
| Data Format | Raw JSON-RPC responses | Pre-indexed, enriched GraphQL |
| Historical Data | No built-in history | Full historical data since L2 |
| Analytics | Manual aggregation required | Built-in joins, aggregations |
| Real-time | Basic subscription support | Rich streaming with filtering |
| Use Case | Transaction submission, node ops | Analytics, monitoring, trading |
| Infrastructure | Run your own nodes | Fully managed, auto-scaling |
