How this service works
Read live Base chain state for any address: ETH balance, latest block, contract/EOA check, ENS name. $0.002 per call. No account or API key needed.
Output
Returns live Base chain data for the queried address: ETH balance (in wei or ETH), the latest block number at time of query, a flag indicating whether the address is a smart contract or an EOA (externally owned account), and the ENS name associated with the address if one exists.
Example use cases
Wallet balance check before DeFi action
“Before I bridge funds, can you check how much ETH the Base address 0xAbC123...456 currently holds and confirm it's a regular wallet, not a contract?”
Smart contract identity verification
“Is the address 0x1234567890abcdef1234567890abcdef12345678 on Base a smart contract or an externally owned account? Also grab its ENS name if it has one.”
On-chain portfolio snapshot
“Give me the current ETH balance and latest block number from Base for address 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe so I can log today's snapshot.”
Technical details
Endpoint
GEThttps://api.mekongtradeintel.com/chain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live Base chain state (balance, block, contract type, ENS) for a specific address without setting up an account or API key — ideal for lightweight, pay-per-call agent workflows on the Base L2 network. Prefer it over Ethereum mainnet RPC wrappers when your target address is on Base specifically.
Side effects
- Invalid or malformed address (not 0x-prefixed or not 40 hex chars) returns an error
- Address not found on Base returns zero balance and no ENS name
- Network congestion may cause delayed or stale block data
- ENS resolution may return null if no name is registered
- Payment failure (insufficient USDC balance) blocks the call under x402 protocol
