Give Claude real prices.
Every AI hallucinates market data. This fixes it. One endpoint. Real-time quotes, options, fundamentals, from the same feed hedge funds pay for.
Your AI is guessing at the number that matters most.
Ask Claude for a stock price. It scrapes some webpage. Returns a 15-minute-old number. You double-check in Excel. The number is wrong. You paste the right one. You do this all day.
What you do now
- Open your MarketXLS model. Find the number.
- Copy it. Switch to Claude. Paste it.
- Ask your question. Get an answer based on one number.
- Ask a follow-up. It forgot. Paste again.
- Do this fifty times a day. Every day.

- Ask Claude anything about the markets.
- It pulls live data. From the same feed your Excel uses.

Questions you're actually asking.
Is this actually real-time?
Yes. Licensed consolidated feeds from QuoteMedia, the same feed institutional terminals use. Options refresh continuously. Each question pulls live numbers, not cached ones.
Which agents work with this?
Any MCP client. Claude Desktop, Cursor, ChatGPT Desktop, Windsurf, and the rest. One endpoint URL, and you are done.
How does billing work?
$99 a month. One flat price. Cancel anytime in one click. No questions, no exit surveys.
Is the data licensed?
Yes. MarketXLS holds the licensing. Your subscription inherits our professional license. Same model as our Excel product since 2014.
Can agents trade through it?
No. It reads data. It does not execute. Execution belongs behind different licenses.
What about historical data?
Intraday bars, daily OHLCV, options history, fundamentals history, macro series. All included at $99.
