Hey Product Hunt! 👋 I'm Marco, the builder behind Agent Toolbelt. The problem I kept running into: Claude is great at analyzing stocks — but it has no live data. Every time I asked it about a company's current valuation, recent earnings, or what insiders were doing, it either hallucinated or gave me stale training data. So I built the tools I wanted to use myself. Five API endpoints that each pull from Polygon, Finnhub, and Financial Modeling Prep in parallel, feed the data to Claude Haiku, and return structured JSON analysis. Not raw data — actual synthesis. A call to `stock-thesis` for NVDA returns a verdict (bullish/neutral/bearish), two paragraphs of analysis, specific strengths and risks grounded in the actual numbers, a valuation read, an insider interpretation, and what to watch next earnings. In about 4 seconds. The tools work via REST, TypeScript SDK, or MCP server — so you can drop them into an existing Claude agent, a LangChain pipeline, or call them directly. Free tier: 1,000 calls/month, no credit card. PAYG credits start at $5. Happy to answer anything — what you'd want to see, what tools are missing, how the prompting works. This is early and I'm very much building in public. Try it at: https://agent-toolbelt-productio...
