How this service works
Pay-per-call read API for Base over x402 v2. Deterministic data, no advice.
Output
Returns a JSON object with: ETH balance (float), USDC balance (float), latest block number seen, chain name ('base'), the queried address, total transaction count, a boolean indicating if it is a smart contract, and the primary Basename (ENS-style name) if one is registered.
Example use cases
Due diligence on a Base wallet
“Before I send payment to 0xAbCd1234abcd1234abcd1234abcd1234abcd1234 on Base, can you check if it's a real wallet or a smart contract, and tell me its transaction history and current ETH balance?”
Resolve a Basename to profile data
“I have the Base address 0x2211d1d0020daea8039e46cf1367962070d77da9 — can you tell me if it has a Basename registered, its USDC balance, and how active it's been on-chain?”
Wallet screening for airdrop eligibility
“Check the on-chain stats for Base address 0xDEADbeefDEADbeefDEADbeefDEADbeefDEADbeef — I need its transaction count and whether it's a contract to decide if it qualifies for our airdrop.”
Technical details
Endpoint
GEThttps://base-reads-api.rafliyaputra.deno.net/base/address-intel?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, pay-per-call on-chain profile data for a specific Base L2 address without committing to a subscription. It is ideal when you want balances, transaction count, contract detection, and Basename resolution in a single call. Prefer it over general Ethereum RPC providers when you need a simple REST interface with USDC micropayment billing via x402 and no API key setup.
Side effects
- Invalid address format (not 0x + 40 hex chars) returns a validation error
- Address has no on-chain activity — balances and tx_count return as 0 with no Basename
- Payment not included or insufficient USDC — x402 payment required error
- Network/RPC outage on Base may cause 503 or timeout
- Address is valid but has no registered Basename — primary_basename field is null or absent
