What is the Bitquery Polygon (MATIC) API?​
It's a GraphQL interface over curated, indexed Polygon (MATIC) data. Write concise queries instead of building and maintaining your own indexer.
What can you build with it?​
Track wallet portfolios and token holders, monitor DEX price/volume and liquidity events, analyze gas and fees, stream mempool activity, compute KPIs over blocks/transactions, and power dashboards or trading systems with real‑time data.
How is it different from raw Polygon (MATIC) RPC?​
| Feature | Polygon (MATIC) RPC | Bitquery Polygon (MATIC) API |
|---|---|---|
| Data Format | Raw JSON-RPC responses | Pre-indexed, enriched GraphQL |
| Historical Data | No built-in history | Full historical data since genesis |
| Analytics | Manual aggregation required | Built-in joins, aggregations, and KPIs |
| Real-time | Basic subscription support | Rich streaming with filtering |
| Use Case | Transaction submission, node ops | Analytics, monitoring, dashboards |
| Infrastructure | Run your own nodes | Fully managed, auto-scaling |
WebSockets and Webhooks​
Most queries can be turned into live streams by switching query to subscription, and consumed over WebSocket. See examples and code snippets here.
