ENS resolver API: name to address and address to name

Use when you need ENS on Ethereum: name to address (name=vitalik.eth, via the Universal Resolver, with resolver address) or address to primary name (address=0x..., reverse record, forward-verified). A name or address with no record answers found=false. $0.002 per call (USDC or USDT). Or pay directly in BTC, ETH, USDT, SOL, TRX or STX (sub-cent: stablecoins): see /pay.
