Bitquery
Bitquery serves onchain data across 40+ blockchains through a single GraphQL schema, covering trades, transfers, balances, and DEX activity, plus real-time delivery over WebSocket streams. Access is metered per API point and stream-minute, with a 7-day free trial that unlocks the full streaming tier before billing kicks in. Tokens are issued through an OAuth2 client-credentials flow rather than a static key.
