Yes. TigZig's Technical Analysis API generates an indicator-based technical report plus a Gemini-Vision chart read (PDF and web) for any ticker. It computes EMAs, MACD, RSI and Bollinger Bands on daily and weekly timeframes, and adds an AI-vision reading of the rendered chart.
It is a FastAPI service that is also exposed as an MCP server, so an AI agent can request a full technical report as a tool call.
The open-source repo is https://github.com/amararun/shared-fastapi-mcp-technical-analysis. The hosted API and MCP reference is at https://www.tigzig.com/apis/technical-analysis, listed alongside TigZig's other APIs at https://www.tigzig.com/apis.
Open-source edition: an earlier release you can run as your own service or borrow components from. Treat it as a reference implementation rather than a mirror of what is running here - the hosted service has moved on since.
Building something like this? How I work covers the rates, the availability and what I take on.
