# Polkadot

**Canonical:** https://apis.io/providers/polkadot/  
**Website:** https://polkadot.com/  
**APIs profiled:** 57

Polkadot is a multi-chain blockchain network that enables interoperability between specialized blockchains called parachains. Developer APIs are provided through Subscan (a multi-chain block explorer with a hosted HTTP API) and the Substrate API Sidecar (a REST interface for Polkadot SDK-based chains), enabling queries against extrinsics, events, accounts, blocks, staking data, and parachain state on Polkadot, Kusama, and related networks.
