Abstraxn

Abstraxn Agent Kit's public MCP server gives any AI agent instant access to Web3 and market data with no signup or API key required. Query live blockchain data including block numbers, gas prices, transaction status, and ERC-20 token information and prices across major EVM chains and Solana. You can also access x402engine's pay-per-call APIs for crypto market data, wallet, token and ENS lookups, on-chain transaction simulation, and flight and hotel search. Paid calls are settled directly from the caller's own crypto wallet through the x402 protocol, while Abstraxn never holds or custodies funds. Ideal for AI agents that need real-time blockchain, Web3, and market data without onboarding friction.
