GET /api/verify
unprobed
Is this Base address a contract or a wallet, and is it active? Live read: code size (contract vs EOA), transaction count (nonce), ETH and USDC balance, at the latest block. Pass ?address=0x... . Useful before paying an unknown payTo. No third-party API, no cache.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
