- [Point Your AI Agent at api.tigzig.com. 40 Million Rows of Public Data, and Half the Bytes Are One File](https://www.tigzig.com/post/tigzig-agent-data-surface-sep2026) - Tags: database-ai, mutual-funds, vigil, portfolio-quants
  The agent data surface at api.tigzig.com now spans over 40 million rows across Indian mutual fund NAVs, ball-by-ball cricket, global macro indicators and India company filings, refreshed daily and free with no signup or key. Cricket is the addition since the August post, covering Tests, ODIs, T20s and the IPL for men and women from December 2001. Over seven days the surface served more than 110,000 API calls and more than 1,700 file downloads, about 40 GB in all, and one file alone, the complete NAV history in Parquet, accounts for more than half those bytes. Also covers the four routes in, the downloads manifest with its row counts and generated_at stamp, conditional requests returning 304, and how to pick between CSV, Parquet, SQLite and DuckDB.

- [Releasing VIGIL Flags. Filter Companies by One or More Signals Instead of Going Company by Company.](https://www.tigzig.com/post/vigil-flags-filter-by-signal-sep2026) - Tags: vigil
  VIGIL Flags lets you filter listed Indian companies by one or more red-flag conditions at once, instead of moving across tabs or checking one company at a time. Twelve conditions cover credit ratings, promoters buying and selling, outsiders crossing five per cent, pledges and lenders invoking them, encumbrance, insolvency and the exchange surveillance flags. Tick several and choose any, which behaves like an OR, or all, which behaves like an AND. Also explains the split that changes how the period filter behaves: eight of the conditions are dated events, while four are the position a company is in right now and read the same whatever period you pick. Plus why promoter sold down and promoter sold five per cent or more are kept apart, since one reads the insider filings at a one point cut and the other reads the takeover filings at five per cent.

- [The Whole VIGIL India Red Flag Database Is Now Published for Download. One API Call Takes the Lot.](https://www.tigzig.com/post/vigil-whole-database-download-sep2026) - Tags: vigil, database-ai
  The VIGIL India red-flag database is now downloadable in full, so a screen across a few hundred companies can be one call instead of hundreds. Covers seven tables: related party transactions, insider trading, credit ratings, promoter pledge, encumbrance events, takeover and SAST filings, and surveillance flags, spanning around 2,500 listed companies and about 426,000 rows. One SQLite file holds all seven at roughly 18 MB, or take a single table as parquet, CSV or TSV, gzipped or zipped, 51 files in total. A manifest publishes row counts, file sizes and a generated_at stamp, and the files answer If-None-Match with a 304 so a scheduled job stops re-downloading unchanged bytes. Rebuilt four times a day. Also explains which tables are event streams and which are current snapshots, and why related party rows are filed on a consolidated basis.

  One address an AI agent can be pointed at, api.tigzig.com, from which it works out which dataset a question needs and pulls the file itself. Close to 38 million rows across India and the US, curated and refreshed daily, free with no signup or key: twenty years of Indian mutual fund NAVs, around 330 macro, credit and valuation indicators across eight groups, and seven filing datasets for Indian listed companies covering credit ratings, insider trading, promoter pledge, encumbrance, takeover, surveillance flags and related party transactions. Usable three ways, by hand in the apps, through the API from code, or as whole-table downloads in CSV, Parquet, SQLite or DuckDB. Includes a downloads manifest carrying row counts and a generated_at stamp so a script can tell whether anything changed before re-pulling, and practical notes on renamed schemes still resolving from an old ISIN.

- [Related Party Transactions for Around 750 Listed Indian Companies Are Now on VIGIL, With the March Half-Yearly Filings In.](https://www.tigzig.com/post/vigil-related-party-transactions-aug2026) - Tags: vigil
  Related party transaction filings for around 750 listed Indian companies on the free VIGIL app, updated to 12 August 2026 with the March half-yearly filings in. About 360,000 rows covering roughly 44,000 counter parties across three half-year periods, browsable in the app, queryable through an open no-key API, or downloadable whole as CSV, Parquet or SQLite. How much a company files turns out to track how many legal entities its group runs rather than how much business it does: the median company files 195 rows while nine file more than 5,000 each, and about 69% of all rows are transactions with group companies. Includes the data nuances that matter before analysis, among them a catch-all transaction type covering 56% of rows, counter parties stored as names rather than identifiers, dates held as text that sort wrongly, and deliberate negative balances meaning payable.

- [Is a Large Investor Building a Position or Selling Down in Your Stock? Takeover Filings on VIGIL, Refreshed Four Times a Day.](https://www.tigzig.com/post/vigil-takeover-sast-filings-aug2026) - Tags: vigil
  SEBI takeover disclosures for Indian listed companies on the free VIGIL app, refreshed four times a day, showing who has been building or cutting a large stake. Anyone crossing 5% of a company has to tell the exchange, and every 2% move after that. Pull up a company to see who has been buying into it, or search an acquirer to see everywhere they have been active. About 12,000 filings across 1,500 companies from January 2024, of which around 3,600 come from outside the promoter group, where mutual funds, insurers and private equity show up. Includes the caution that debenture trustees also sit in that non-promoter group holding shares as security rather than as a view on the company. Downloadable as CSV, Parquet or SQLite, or hand the open no-key API straight to an AI agent with the prompt included.

- [Insider Trading Disclosures for Indian Listed Companies, on Vigil, Updated Four Times a Day.](https://www.tigzig.com/post/vigil-insider-trading-disclosures-aug2026) - Tags: vigil
  Insider trading disclosures for Indian listed companies on the free VIGIL app, refreshed four times a day, showing whether the people inside a company have been buying or selling, when, how much, and the holding before and after. These are filings mandated by SEBI's Prohibition of Insider Trading regulations, covering promoters, the promoter group, directors, key managerial personnel and designated employees once a quarter's trades cross a value threshold, so every row carries a named person and a date. Around 38,000 disclosures across about 1,500 companies going back to early 2024, downloadable whole as CSV, Parquet or SQLite or queryable through an open API with no key. Also a caution for anyone grouping by role: the category is free text, with 18 spellings for roughly six roles and one in six rows blank, published as filed rather than recoded.

- [667 Stocks Are Under NSE and SEBI Surveillance. Almost All of Them Sit Outside the Nifty 500.](https://www.tigzig.com/post/nse-sebi-surveillance-667-stocks-aug2026) - Tags: vigil
  As of 7 August 2026 there are 667 Indian listed companies carrying an NSE or SEBI surveillance flag, and the breakdown shows it is overwhelmingly a small and micro cap story. Only 20 sit in the Nifty 500, two of those in the Nifty 100 and none in the Nifty 50. Another 24 are in the Microcap 250. The remaining 623 fall outside the Nifty Total Market entirely, including roughly 171 on the SME platform and 41 in the suspended or Z group. Flags also stack: 62 companies carry two, 27 carry three and 4 carry four. ASM, GSM and ESM cover price and volume surveillance, with separate fundamental flags. Checkable per stock in the VIGIL app, updated daily, and downloadable via a free API.

  A troubleshooting field guide for the free tigzig.com data APIs (MFPRO mutual fund NAV, TREMOR macro/market, VIGIL India red flags, Yahoo Finance tools), built from real server-log patterns.

Ends with the copy-this-page-to-your-AI troubleshooting recipe and the full human + AI-agent documentation link set (API catalog RFC 9727, MCP server registry, raw markdown data dictionaries).
