# How do I explore the TigZig data surface with my AI agent?

**Paste one line into your agent:** "Go to api.tigzig.com. Tell me what's there and how we can pull it." Free, no signup, no API key.

**What the agent finds at the root.** [api.tigzig.com](https://api.tigzig.com) returns a JSON index that points to the interactive docs (`/docs`), the OpenAPI spec (`/openapi.json`), the API catalog in the standard RFC 9727 format (`/.well-known/api-catalog`), the list of bulk downloads (`/downloads`) and a health check. Every public API is in that catalog, with its own docs.

**What the data covers.** Macro and markets data in eight categories (US macro, credit, valuation and insurance, India macro, global macro, markets and currencies) on the TREMOR API, Indian mutual funds (NAV history and scheme details), India company signals from VIGIL, and a cricket database queryable with SQL. For each one the agent can ask for a single item, a batch, or take the whole table as a file and work on it locally. Callers reach the APIs from Google Sheets and Apps Script, Excel and Power BI, n8n, Zoho and Power Automate workflows, Python and Node scripts, and AI agents including Claude, ChatGPT, Codex, Mistral and Grok.

**Four things worth telling your agent up front:**

- **Thirteen US monthly series have no value for October 2025,** the month of the government shutdown: ten from the jobs survey (including the unemployment rate, labour force participation and median weeks unemployed) and three CPI series. FRED publishes that month as blank, so a monthly change across it skips a month. Do not interpolate. More on the jobs survey gap: [why the two US jobs surveys disagree](https://www.tigzig.com/agents-faq/why-do-the-two-us-jobs-surveys-disagree).

- **Mutual fund values that belong to the fund repeat on every plan.** AUM, fund manager and benchmark show up on each plan of a fund, so count only rows where `fund_dedup_flag` is true when you total fund size: [scheme details for Indian mutual funds](https://www.tigzig.com/agents-faq/where-can-i-get-ter-fund-manager-and-riskometer-for-indian-mutual-funds). TER is left blank where the exact SEBI scheme code is missing or shared with another fund.

- **The cricket SQL endpoints carry statistical functions** such as percentiles, standard deviation and mode. A few, such as median, work on the DuckDB engine only: [query limits on the cricket SQL API](https://www.tigzig.com/agents-faq/what-are-the-query-limits-on-the-cricket-sql-api).

- **When a call returns an error,** the response body usually names the fix.
