From the sources

Financial Data API provides market data, company fundamentals, alternative data, and much more. Over 20 years of historical data available, including information on 15.000+ stocks, 20.000+ funds, 2000+ ETFs, 13.000+ OTC securities.

Easily query financial datasets, apply multi-operator filters, and extract custom fields. Explore the Universal Query API documentation, endpoint parameters, and dataset specifications.

Instead of maintaining separate endpoints for each data type, use /api/v1/universal-query to access all our financial data from one place. Query parameters give you direct control over the response payload. You can select the dataset, request specific fields, and apply multiple filters – keeping payload sizes small and your integration clean. To maintain optimal performance, the maximum number of records returned per request is calculated dynamically based on query complexity, target dataset, and requested fields. Client applications must inspect the X-Record-Limit HTTP response header for the applied limit and use it with the offset parameter to paginate through the remainingfrom financialdata.net

  Pane – Give your AI access to your financial data via MCPMar 2026 · pane.money · ▲10

  Hey HN! Today I'm launching Pane, a tool that gives AI context on your financial data. Once connected, any MCP-compatible client (Claude, Cursor, ChatGPT, etc.) can answer questions like: - "What did I spend on food this month?" - "What's my net worth right now?" - "Show me my recurring subscriptions" - "How much do I owe across all credit cards?" - "What are my investment holdings?" It's been really transformative in helping me and some of my friends understand their finances, where they are overspending, or even being double billed in some cases. I'm very aware that this is a somewhat…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
