How this service works
Payment for Quicknode RPC access. Options: per-request ($0.001/request), nanopayment ($0.0001/request via Circle Gateway), or credit drawdown with SIWX authentication.
Output
A JSON-RPC 2.0 response object containing the result of the requested Ethereum method call (e.g. block number as hex string, transaction receipt object, contract return data, balance in wei), or an error object if the call failed.
Example use cases
Monitor Base contract state changes
“I need you to poll the latest block on Base and then call our smart contract to check if the token balance has updated since the last check — can you do that without needing a subscription?”
Verify transaction finality on Base
“A user just sent us a transaction on Base mainnet. Can you grab the transaction receipt and confirm it went through and is included in a final block?”
Calculate gas costs before executing
“Before I deploy this contract to Base, can you check what the current gas price is so I can estimate total transaction costs?”
Technical details
Endpoint
POSThttps://x402.quiknode-cf.pro/base-mainnetWhen to prefer
Choose this endpoint when you need reliable, high-performance JSON-RPC access to Base mainnet and want pay-per-request pricing via x402 micropayments rather than a subscription. Ideal for agents making sporadic or bursty RPC calls where nanopayment ($0.0001/req via Circle Gateway) or per-request ($0.001/req) billing fits better than a monthly plan. Prefer over generic public RPC endpoints when uptime and throughput guarantees matter.
