Output
A JSON-RPC response object containing the result of the requested method call (e.g. block number as hex, balance in wei, transaction receipt object, contract return data), with fields: id, jsonrpc, and result (or error if the call failed).
Example use cases
Example prompt
“Can you call eth_getBalance on Base mainnet for the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 using QuickNode's RPC — I need to know the current ETH balance in wei.”
Technical details
Endpoint
POSThttps://x402.quicknode.com/base-mainnetWhen to prefer
Use this endpoint when you need reliable, paid-tier JSON-RPC access to Base mainnet (the Coinbase-incubated EVM L2) with per-request micropayment billing. Prefer over free public RPCs when you need guaranteed uptime and rate-limit headroom. Choose over other QuickNode sibling endpoints specifically for Base mainnet (not Ethereum, Mantle, or other chains).
