Crypto Derivatives API & MCP for Bots and AI Agents

REST + WebSocket API and an MCP endpoint for open interest, funding, liquidations, order flow and risk briefs — exchange-exact numbers, conclusions computed server-side, free API key.

Endpoints

REST base: /api/v1 — /coins, /funding, /oi, /oiboard, /flows, /liquidations, /liqmap, /orderflow/footprint, /orderflow/cvd, /orderflow/spoof, /brief, POST /ask. WebSocket: /ws. MCP: /mcp. Full machine-readable guide: /llms.txt, OpenAPI: /api/v1/openapi.json.

REST, WebSocket and MCP

The conclusions (brief, regime, cascades, maps, dispersion, carry, microstructure, tokenized stocks) and the live snapshots (open interest, funding, long/short, recent liquidations) are free without a key at 60 requests a minute per IP. History and positions are metered: a free key includes 100 calls a day, Pro and Bot keys (USDC on Arbitrum) are unlimited, or one x402 payment per call. WebSocket pushes funding and liquidation events. The MCP endpoint is stateless streamable HTTP with 42 tools (a lite endpoint at /mcp/lite carries the 13 tools that return conclusions); AI agents call it without authentication. Guide for agents: /llms.txt.
