Bitquery vs Covalent
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.
Covalent's blockchain-data platform rebranded to GoldRush, unifying wallet balances, transaction history, NFT ownership, and token/DEX pricing across 100+ EVM and non-EVM chains behind one API, plus JSON-RPC endpoints for 30+ EVM networks. New accounts get a 14-day trial (25,000 credits) before moving to a paid plan or per-request (x402) billing with no monthly minimum. All data comes back as JSON.
