This is a pay-per-request Solana API that skips API keys and subscriptions entirely. Agents pay in USDC using the x402 protocol, then get access to wallet analytics, token prices via Jupiter, DeFi position data, swap execution, and liquid staking yield comparisons. Pricing ranges from half a cent for token prices to 25 cents for swap transaction building. The MCP server exposes 13 tools covering everything from portfolio breakdowns to P&L calculations. Reach for this when you want Claude to analyze Solana wallets, quote swaps, or assess DeFi positions without managing credentials. Built on Helius RPC with Redis caching and full TypeScript types.
