Crypto Wallet APIs
Wallet APIs here look up or vet addresses rather than hold funds. CoinStats reads wallet balances and DeFi positions across 120+ chains, and Deep Blue Alpha follows Ethereum whale wallets. For compliance and fraud checks, AI DECISIONS screens addresses for sanctions exposure and mixer use across six chains, and TWZRD Agent Intel scores Solana wallets for wash trading before you accept payment.
