Give a transaction hash + chain and get back whether it mined successfully, reverted, or is still pending in the mempool, plus block number, confirmations, timestamp, sender and recipient, value transferred (native unit), gas used, effective gas price, total fee paid, any contract created, and event-log count. Chains: base, ethereum, polygon, arbitrum, optimism. Real-time post-training chain state — use it to confirm a payment settled, detect a reverted transaction, or wait for confirmations before acting. Unknown hash returns 404. Sibling of /api/crypto/gas-oracle (fees) and /api/crypto/address-validate (format).

Resolve ENS (Ethereum Name Service) names and addresses live on Ethereum mainnet. Pass query as either an ENS name (e.g. "vitalik.eth") → returns the Ethereum address it points to, or a 0x address → returns its primary ENS name (reverse record). Either way it also returns the profile text records: avatar, email, url, twitter (com.twitter), github (com.github), and description. A live on-chain lookup agents can't do from their sandbox, and ENS records change after training cutoffs. Wallet UX, address-book resolution, on-chain identity. Returns address:null for an unregistered or unset name.
