perp

perp_get_funding_rates

Use this to read perpetual futures funding rates. Two modes, same call, same price: MARKET SCAN (omit symbol) -- returns every USDT perp on Binance and Bybit ranked by funding, so you can find an opportunity in one paid call instead of probing symbol by symbol. Sort by "abs" (largest magnitude, default), "highest" (shorts get paid most), "lowest" (longs get paid most) or "spread" (largest cross-venue gap = cash-and-carry candidates). SINGLE SYMBOL (pass symbol) -- returns Binance, Bybit and OKX side by side for that asset, with open interest, mark price, next funding time and a sentiment read. Data returned per market: 1. symbol: base ticker (BTC, ETH, SOL...) 2. venues: per-exchange funding rate, percent and annualized rate 3. avgRate / annualizedRate: mean funding across venues, annualized as rate * 3 * 365 4. direction: "short opportunity" when funding is positive (longs pay shorts), "long opportunity" when negative 5. spread / spreadAnnualized: gap between the cheapest and dearest venue 6. longVenue / shortVenue: where to take each leg of the cross-venue carry 7. openInterest, markPrice Example scan output: {"scan":true,"totalMarkets":812,"venues":["Binance","Bybit"],"sort":"abs","markets":[{"symbol":"PEPE","venues":{"Binance":{"fundingRate":0.0005,"annualizedRate":54.75},"Bybit":{"fundingRate":0.0003,"annualizedRate":32.85}},"avgRate":0.0004,"annualizedRate":43.8,"direction":"short opportunity (longs pay shorts)","spread":0.0002,"spreadAnnualized":21.9,"longVenue":"Bybit","shortVenue":"Binance"}]} Example single-symbol output: {"symbol":"ETH","found":true,"exchanges":3,"summary":{"averageRatePercent":"0.0082%","annualizedAverage":"8.98%","sentiment":"bullish (longs pay shorts)"},"rates":[{"exchange":"Binance","fundingRate":0.000082},{"exchange":"Bybit","fundingRate":0.000075},{"exchange":"OKX","fundingRate":0.000091}]} Use this FOR finding carry and basis trades, timing perp entries, and monitoring funding costs on open positions. Do NOT use for spot prices -- use dex_get_swap_quote instead. Do NOT use for DeFi yields -- use defi_find_best_yields instead. Do NOT use for Hyperliquid-specific rates -- use hyperliquid_get_funding_rates instead. Note: market scans cover Binance and Bybit. OKX has no bulk funding-rate endpoint, so it is included only when you query a single symbol. POST variant of perp_get_funding_rates -- same params passed as a JSON body instead of a query string. Send {} to get the default market-wide scan.

Perpetual Funding Rates API — questions

Answers built from our own checks of this server.

What can Perpetual Funding Rates API do?

It exposes 1 tools, read directly from the server on our last check. Among them: perp_get_funding_rates. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Perpetual Funding Rates API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 17 ms. The bar chart above shows every period we have measured.

The registry lists Perpetual Funding Rates API as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Perpetual Funding Rates API?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Perpetual Funding Rates API need an API key?

No. Perpetual Funding Rates API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

Is Perpetual Funding Rates API open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at funding-rates.api.klymax402.com, which runs on its operator's own terms.
