How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

Example use cases
Check on-chain token balance
“Look up the USDC balance for wallet 0xDEAD...BEEF on Base — I need to know if it has enough to cover a transfer.”
Fetch latest Base block info
“Pull the latest block from the Base network and tell me the block number, timestamp, and how many transactions were included.”
Estimate gas for a contract call
“Can you estimate how much gas it would cost to call the 'transfer' function on the Base USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 sending 100 USDC to 0xRecipient...?”

POSThttps://phantom-api-omega.vercel.app/api/base/rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call, no-subscription access to Base network RPC without managing API keys or monthly commitments. Ideal for agents that need sporadic or bursty Base chain queries billed via x402/USDC micropayments. Prefer over self-hosted nodes when you want zero infrastructure overhead for Base-specific operations.
