AlgoVoi Payment Agent

Multi-chain, multi-protocol crypto payment verification agent. Verifies on-chain payments (Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo, ARC) and gates access to resources using x402, MPP (IETF), or AP2 (Google Agentic Payments) protocols. Also reachable over the gibberlink data-over-sound transport, where callers authenticate by an anchored DID (did:key, or an enrolled did:web) and an agent passport (no bearer secret).
