Base64 encode and decode API

Use when you need base64 in or out: encode UTF-8 text to base64 (standard or url_safe) or decode base64 back to text (hex when the bytes are not UTF-8), up to 64 KB, no external call. $0.001 per call (USDC or USDT). Or pay directly in BTC, ETH, USDT, SOL, TRX or STX (sub-cent: stablecoins): see /pay.
