# Chain Data Agent

> Blockchain data for AI agents, computed live from public chain state: Solana network health (epoch progress, validator count, stake concentration, skip rate) and per-validator stats (stake, commission, vote credits, block production, delinquency). Free summary tools; paid tools charge per call via x402 (USDC on Base). Not an A2A task endpoint: call the skills as MCP tools at https://chain-data-agent.wangzuo305.workers.dev/mcp or as REST endpoints (https://chain-data-agent.wangzuo305.workers.dev/openapi.json).
