How this service works
Base address snapshot: ETH balance, tx count, contract or EOA
Output
Returns a JSON object containing the ETH balance of the address, its total transaction count on Base, and its account type classification (contract vs. EOA — externally owned account), giving a concise onchain profile of the address.
Example use cases
Wallet due diligence before a transfer
“Before I send funds, can you check 0xAbCd1234567890aBcDeF1234567890abcDEF1234 on Base — what's its ETH balance, transaction count, and is it a contract or a regular wallet?”
Classify airdrop recipient addresses
“I need to know if 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b is a smart contract or a normal EOA on Base, and what its current ETH balance is.”
Monitor a DeFi protocol's treasury
“What's the current ETH balance and transaction count for Base address 0xDeAd000000000000000042069420694206942069, and is it a contract account?”
Technical details
Endpoint
GEThttps://agenttoll-pi.vercel.app/api/base/address/:addressWhen to prefer
Use this endpoint when you need a quick, single-call summary of a Base network address — specifically when you want ETH balance, transaction count, and contract/EOA classification in one shot without querying a block explorer manually. Prefer this over general blockchain APIs when you're working specifically on the Base L2 and need low-latency, pay-per-call access without API key setup.
Side effects
- Invalid address format (not a 0x-prefixed 40-hex-char string) returns a validation error
- Address not found or never used on Base may return zero values for balance and tx count
- RPC or node connectivity issues may cause 5xx errors
- Payment failure (x402) if USDC balance is insufficient blocks the request
- Rate limiting if too many requests are made in a short window
