Polygon JSON-RPC API

GetBlock provides fast and reliable access to Polygon nodes via the JSON-RPC API. Connect to the Polygon network without running your own infrastructure.

The Polygon JSON-RPC API is the standard interface developers use to communicate with the Polygon blockchain. It allows decentralized applications (dApps) to read on-chain data, query smart contracts, and submit transactions without the need to run a local copy of a full blockchain node
