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.

APIs from Tigzig

Free, open APIs. No authentication on read endpoints. Two kinds: data APIs that serve our datasets, and analytics APIs that compute a report from inputs you send. This page is a directory - each card links out to that API's own interactive docs, OpenAPI spec, and (for most) an MCP server.

7 public APIs
5 MCP servers
20M+ rows served
~300 macro indicators
Open no auth required
Beta. Endpoints are stable; rate limits, formats, and parameters may evolve. Canonical machine list at api.tigzig.com/.well-known/api-catalog.
AI agents: every API here is listed in the machine-readable catalog (RFC 9727) and exposes an OpenAPI 3.1 spec at {base}/openapi.json. Start at the catalog or the site index rather than parsing this page.

Data APIs

#

Serve structured datasets. Hit the query endpoints, or download the whole database in one file (CSV / TSV / Parquet / SQLite / DuckDB).

TREMOR / Tigzig V2 Unified Data Surface

APIMCPDATA

Global macro, credit, valuation, insurance, India, markets and FX indicators across 8 categories (FRED, NY Fed, FDIC, NCUA, RBI, MoSPI, ECB, OECD, Shiller, NSE). Category-first navigation: pick a domain, drill in. Pull any series, or bulk-download the whole database.

Analytics APIs

#

Send inputs (tickers, a portfolio) and get a computed report or dataset back. Each is open source and also runs as an MCP server over the same backend.
