Zerion is an established wallet/portfolio product whose API exposes portfolio balances, DeFi positions, transaction history, PnL, NFTs, prices, and swap quotes across 40+ chains. It added x402 payment support on Base in 2026, letting agents pay roughly $0.01 USDC per request without an API key, and ships an MCP server and a JSON-first CLI for AI agents.
