quite interesting to trade with grok while my agent runs the research in the background
built an arb scanner for myself using claude + openfinance. polymarket vs kalshi odds in one view, took an evening
wait, my agent has access to all of defi, perps AND prediction markets? one api key? wow
told my agent to watch btc funding rates and ping me when they flip. it just did it
I asked it to buy $10 of YES on the 2028 election market. It showed me the price, I confirmed, and the order filled on Polymarket. That was it.
Individual experiences. Results vary and are not indicative of future performance.
It connects AI apps like Claude, ChatGPT, Cursor and Grok to OpenFinance so they can research markets and place trades in plain language.
Crypto, DeFi tokens, memecoins, every Hyperliquid market, onchain stocks and forex, and Polymarket prediction markets, all from one connection.
No KYC on OpenFinance. If you connect a broker account, that broker's own rules apply.
Under 60 seconds: add the URL, sign in, fund with a debit card.
Every request needs either OAuth sign-in or an API key in the x-api-key header. You can create an API key in your account.
Your AI app shows the order details it is about to send, and you can ask it to confirm with you before every trade.
No. OpenFinance at openfinance.tech is a separate product, not related to openfinance.sh.
OpenFinance charges 2.5 basis points (0.025%) on Hyperliquid trades, perps and spot, and 25 basis points (0.25%) on Polymarket trades and onchain swaps. Venue, broker and network fees apply on top.
Not through the MCP today. Options are available in the OpenFinance app through your connected IBKR or Robinhood account.
Risk disclosure. Trading crypto, perpetual futures, options, tokenized stocks, forex and prediction markets carries a high risk of loss, and leverage can magnify losses. AI tools can misread instructions or act on wrong data; you are responsible for every order placed through your AI app. Nothing on this page is financial advice, and past results do not predict future returns.
