Trading / DeFi / market data x402 base solana

The service's listing describes it this way: Gap table for trade.xyz (Hyperliquid HIP-3) stock perps: perp mark/oracle vs live stock price and Solana xStock, basis, hourly and annualized funding, open interest; venues=all adds Aster and Lighter marks, funding and cross-venue spreads. Use when an agent needs current premium/discount or funding arbitrage signals across many tokenized stocks at once (cheapest call). Errors: 402 payment required, 502 upstream error. Website
