Liquidation Oracle X402 MCP Server

DeFi Liquidation Oracle API

DeFi liquidation levels from Aave, Compound, Morpho -- at-risk positions, price triggers, aggregate exposure. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

{
  "mcpServers": {
    "liquidation-oracle": {
      "url": "https://liquidation-oracle.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl "https://liquidation-oracle.api.klymax402.com/api/levels"
# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

• currentPrice -- current market price of the collateral
• distancePercent -- how far current price is from liquidation (%)
• aggregateAtRisk -- total USD value at risk per protocol
• protocol -- lending protocol name (Aave, Compound, Morpho, Venus)

Example response:

{"positions":[{"protocol":"Aave V3","collateral":"WETH","collateralUsd":245000,"liquidationPrice":2850.00,"currentPrice":3100.00,"distancePercent":8.06}],"aggregateAtRisk":{"Aave V3":12500000},"totalPositions":42}
