Real-time Hyperliquid liquidation-risk scoring, pay-per-call via x402 on Base USDC.

hlrisk delivers real-time Hyperliquid BTC/ETH liquidation-risk data via x402 (HTTP 402 Payment Required), paid per call in USDC on Base — no API keys, no signup, no subscription. The flagship endpoint is built from real on-chain position data: notional at risk if price moves ±1%/3%/5%, the position closest to liquidation, and current funding rate. A free MCP server exposes read-only versions of the core tools for MCP-enabled agent frameworks. A live demo shows a Claude agent autonomously discovering a 402 challenge, paying for the data, and using the result — no human in the loop, no pre-registered API key.
