Network Access

Quicknode's Polkadot endpoint provides access to both AssetHub and Relaychain networks through a unified interface.

AssetHub handles most current operations including token transfers, NFT management, and parachain state queries. REST API calls target AssetHub by default:

# AssetHub (default)
curl 'https://your-endpoint.pro/blocks/head'

Polkadot Relaychain provides access to relay chain data, validator information, and historical records. Prefix REST API calls with /rc to access the relaychain:

# Polkadot Relaychain
curl 'https://your-endpoint.pro/rc/blocks/head'

JSON-RPC methods operate without network prefixes and maintain standard compatibility across both networks.
