How this service works
Return point-in-time public native ETH and native Base USDC balances for one EVM address from Base mainnet RPC.
Output
Returns a point-in-time balance snapshot for the queried EVM address on Base mainnet, including the native ETH balance and the native Base USDC balance, expressed as on-chain values at the moment of the RPC call.
Example use cases
DeFi portfolio spot check
“Can you pull the current ETH and USDC balances on Base for wallet address 0xAbC123...def456 so I can see what I'm working with before I make a move?”
Verify payment receipt on Base
“I'm expecting a USDC payment to 0x1a2b3c4d5e6f7890abcdef1234567890abcdef12 on Base — can you check if the balance has changed and how much USDC is there right now?”
Onchain wallet audit for due diligence
“I need a snapshot of the native ETH and USDC holdings for this Base wallet — 0xDeAdBeEf0000000000000000000000000000dEaD — as of right now for my records.”
Technical details
Endpoint
GEThttps://trinity-throw-thursday-gravity.trycloudflare.com/x402/base-wallet-balanceWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.01 USDC) point-in-time balance check for native ETH and native USDC on Base mainnet for a single EVM address. Prefer it over general blockchain explorers when you need a structured, machine-readable JSON snapshot rather than a human-facing UI, or when operating within an x402 micropayment agent workflow on Base.
Side effects
- Invalid EVM address format (must match ^0x[0-9a-fA-F]{40}$) — returns a validation error
- Address not found or zero-balance address — returns zero values rather than an error
- Base mainnet RPC unavailability or timeout — returns a service error
- Missing required 'address' query parameter — returns a bad request error
- Payment not received (x402 flow) — request rejected before executing
