How this service works
Live EVM chain reads for agents across Base, Ethereum, Arbitrum, Optimism and Polygon: gas fees, wallet balances (native + USDC), transaction status, ERC-20 metadata and ENS resolution. Every answer is read from public RPC nodes at call time. $0.001 per call. By orbit-builder.
Output
A JSON object containing: the queried chain name, the EVM address, native coin balance in both wei and human-readable decimal form with symbol, USDC balance in both atomic and decimal form with the USDC contract address, transaction count (nonce), a boolean indicating whether the address is a contract, a boolean for EIP-7702 delegation status, and a block explorer link.
Example use cases
Portfolio balance snapshot across chains
“Can you check the ETH balance and USDC balance for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on all five supported chains — Base, Ethereum, Arbitrum, Optimism, and Polygon?”
Verify wallet is funded before transfer
“Before I send funds, can you confirm that 0xAbCd1234567890abcdef1234567890ABCDEF1234 on Arbitrum has any ETH and USDC balance, and tell me its transaction count?”
Check if address is a contract
“Is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base a smart contract or a regular wallet, and what's its current USDC balance?”
Technical details
Endpoint
GEThttps://orbit-chain.orbit-builder.workers.dev/v1/balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, multi-chain wallet balance lookup covering both native coin and USDC in a single call, especially when you also need contract detection or EIP-7702 delegation status. It is ideal for agents verifying wallet funding, auditing on-chain activity, or enriching user profile data with live blockchain state across the five most popular EVM networks. Prefer it over raw RPC calls when you want a structured, normalized response without managing multiple provider connections.
Side effects
- Invalid or malformed address returns an error response
- Unsupported chain name returns an error
- Public RPC downtime or rate-limiting may cause timeouts or failed reads
- Address with zero activity still returns valid zero-balance response
- Network congestion may cause stale or delayed RPC data
