How this service works
On-chain facts for any Base address: EOA or contract, first transaction and age, transaction count, ETH and USDC balances, top 10 tokens held with USD value when known, recent contracts created. Information, not investment advice.
Output
Returns a JSON object with the account type (EOA or contract), ETH and USDC balances, a list of top token holdings with contract addresses and balances, total transaction count, account age in days, first transaction details, contracts created, and the data sources and fetch timestamps used to compile the report.
Example use cases
Check wallet balance before payment
“Before I send funds, can you check the ETH and USDC balance of this Base wallet: 0xEb81d0a682B2116069Cc00A215f618A1074B052b?”
Vet a new counterparty's wallet history
“I'm about to do business with someone on Base — can you look up their wallet 0x1234567890abcdef1234567890abcdef12345678 and tell me how old the account is, how many transactions they've done, and whether they've ever deployed a contract?”
Audit token holdings of a DeFi address
“Can you give me a full breakdown of the tokens held by the Base address 0xEb81d0a682B2116069Cc00A215f618A1074B052b, including any smaller tokens beyond just ETH and USDC?”
Technical details
Endpoint
GEThttps://audit-site-web.pga-agent.fr/api/base-wallet-facts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured summary of a Base (chain 8453) wallet's on-chain state — balances, token holdings, transaction history, and account age — without needing to write custom RPC queries. Prefer this over raw RPC calls when you want aggregated data from multiple sources (public RPC + Blockscout) in a single call. Not suitable for other EVM chains (Ethereum mainnet, Polygon, etc.) or for real-time streaming of transactions.
Side effects
- Invalid or malformed address (not a valid 0x + 40 hex char string) returns an error
- Address not found on Base chain 8453 may return zero balances or empty token list
- RPC or Blockscout data source temporarily unavailable may result in partial data
- Rate limiting or payment failure may prevent the call from completing
