Pay-per-call market and on-chain data API over x402 (USDC on Base): multi-venue consensus crypto prices, DeFi TVL and stablecoin supply, DEX volume and protocol fees, yield pool history, and keyless read-only on-chain reads (balances, receipts, logs, eth_call) on Base, Ethereum, Arbitrum, Optimism and Polygon. No accounts, no API keys; every paid response is normalised and falls back to a second data provider.
