Quickstart -- MCP

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

{
  "mcpServers": {
    "hyperliquid-whales": {
      "url": "https://hyperliquid-whales.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

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