Node providers stop at raw blocks. Wallet APIs start at balances, on fewer chains. GoldRush covers the whole stack on 100+ chains, from block 1 to a plain-English answer.

Block 1, the chain tip and each dated block from the GoldRush block endpoints. The tip is refreshed hourly and counts on at each chain's recent block rate.
One call returns the transaction with its events decoded and its value priced. Flags add internal transfers, input data, state changes and a plain-English classification, and traces come through JSON-RPC on the same key.

GoldRush by Covalent is a multichain blockchain data API. It covers 100+ EVM and non-EVM chains including Ethereum, Solana, Base, Polygon, BNB Chain, Arbitrum, Optimism, Avalanche, and Bitcoin. A single API returns wallet balances, full transaction history, NFT metadata, token prices, OHLCV data, DEX pair analytics, and JSON-RPC. GoldRush also supports the x402 pay-per-request protocol, so autonomous AI agents can call the API without signing up.
