Documentation Overview
bykaranteli-mcp
MCP (Model Context Protocol) server for live crypto derivatives data: funding rates, cross-exchange funding arbitrage, open interest pressure, liquidations, options, ETF flows, Fear & Greed and BTC dominance.
67 read-only and account tools over the public JSON API of bykaranteli.com: the market data tools only read, and the alert and watchlist tools act on your own account through your key (Account tools). Since 2026-09-10 the API asks programs for an account key: a free key comes with any verified account at https://bykaranteli.com/dashboard/api (30 requests a minute and 15,000 a month, public depth), and the Builder, Business and Scale plans raise the rate and the monthly fair use and unlock member depth (LiqMap on seven timeframes, 5-minute series) and a monthly allowance of x402 catalog calls within each plan's history window (Plans and paid depth). Set it as BYKARANTELI_API_KEY. Data covers Binance USDT-M perpetuals; funding arbitrage, liquidations, order book depth, options, positioning and insurance funds add the other venues each board lists on bykaranteli.com/coverage.
Hosted endpoint (no install)
Paste https://mcp.bykaranteli.com as a custom connector in any MCP-capable
assistant. The same tools, nothing to install. Every tool call needs your
account key (free at https://bykaranteli.com/dashboard/api); connecting and
listing the tools work without one. The key travels one of three ways:
- the request header
x-api-key: bk_...(claude.ai custom connectors, Cursor, Claude Code); - the request header
Authorization: Bearer bk_...; - the address
https://mcp.bykaranteli.com/?key=bk_...for clients that cannot send headers (ChatGPT). Treat that address like a password and revoke the key if it leaks.
Or sign in with OAuth 2.1 where the client offers it (claude.ai custom connectors: Authentication, Sign in; ChatGPT connectors: OAuth): the client registers itself (RFC 7591, PKCE S256), you approve it once on bykaranteli.com and it runs on a key of your own account, which the Data and API page lists under connected apps. Discovery: https://mcp.bykaranteli.com/.well-known/oauth-protected-resource.
A free account covers the API and the hosted MCP on one monthly counter; Builder and above bring higher rates and member depth.
