# What free financial-data APIs does TigZig offer?

TigZig offers a range of free financial and analytics APIs, many also exposed as MCP servers so AI agents can call them as tools. The current set includes:

- **MF NAV API** - daily NAV for 38,000+ Indian mutual fund schemes (AMFI).

- **Vigil API** - India corporate red-flag signals from NSE across 7 tables.

- **Tremor** - global macro, credit and markets indicators (FRED, NY Fed, FDIC, NCUA, RBI, ECB and more).

- **Yahoo Finance** - financials, prices and market data (~15 endpoints).

- **QRep / QuantStats / FFN** - security and portfolio performance and risk reports.

- **Technical Analysis** - indicator plus chart-read technical reports.

- **Database Query** - read-only SQL over Postgres and DuckDB.

- **Markdown to PDF** - report rendering.

The full catalog, with endpoints and MCP cards, is the unified hub at [https://www.tigzig.com/apis](https://www.tigzig.com/apis).

**You do not have to pick one.** Point an AI agent with web access at `api.tigzig.com` and ask in plain English. That address is a **machine-readable catalog**: the agent reads it, works out which service holds the dataset, opens that service's OpenAPI spec and builds the call itself, including the bulk-file download where there is one. Works with Claude, Claude Cowork, ChatGPT Work and AI coders; plain ChatGPT without web access cannot reach it.
