Best used with an AI agent

40+ live apps, open data APIs, MCP servers, and 200+ guides - more than anyone wants to click through. Point your AI here and it reads the whole map and does the work: finds the tool, pulls the data, runs the analysis, and hands you the links.

Here for the open-source code? Your agent finds the right repo for you - and can even clone and deploy it.

Prefer to explore on your own? Go right ahead.

Paste this to Claude Code, Codex, or any AI agent:
Go to tigzig.com and read tigzig.com/llms.txt. It is a practitioner toolkit - 40+ analytics apps, open no-auth data APIs, MCP servers, open-source repos (github.com/amararun), and 200+ build guides. Help me [your task]. Surface the exact links; where there is an API or MCP, call it directly; and if I want to self-host, find the repo and help me deploy it.

The Data Behind My Analyses Is Now Open. Download the Whole Database or Query a Single Row.

Published: June 5, 2026

TIGZIG Data APIs - public, no auth, free to use. Download the whole database, or query a single row. Most APIs never give you the full dataset; these do. Three open APIs powering the Tigzig apps - MF NAV (18,000+ schemes, 13 yrs, ~20M daily NAVs), VIGIL (corporate signals: ratings, insider, pledge, SAST, RPT), TREMOR (~300 indicators from FRED, RBI, Fed, FDIC). Query live across ~30 endpoints, take it all in SQLite, DuckDB, Parquet, CSV or TSV refreshed 3x a day by the CI/CD that powers the apps, or plug in an agent via the live MCP server.

The analyses I've been posting these past months.. they all run on the same data. And that data is now open to everyone.

US delinquencies, private credit, life insurance, the markets piece. All off primary data, FRED, RBI, Fed, FDIC, refreshed three times a day by the same pipeline that runs the live apps.

Pull a single row, or take the whole database.. SQLite, DuckDB, Parquet, CSV. Query it live. Or point your own agent at the MCP and let it do the fetching... or wrap the API in your own.

No auth. Rate limited. Free to use.
