FAQ

Frequently asked questions

The TagX Stock Market API returns stock and ETF/fund data as structured JSON: company info, price history (any period and interval), OHLC bars, splits, and news. It also serves deep fundamentals (balance sheet, income statement) and analyst data: earnings estimates and history, EPS trend and revisions, growth and revenue estimates, recommendations, and upgrades/downgrades, plus ESG/sustainability data. Fund endpoints add holdings and historical NAV.

The API covers roughly 45 global exchanges, accessed by appending a ticker suffix such as .L for London, .T for Tokyo, or .NS for India's NSE (US tickers need no suffix). Asset coverage spans stocks, ETFs, and mutual funds, plus EU-market bonds looked up by ISIN and economic indicators for 150+ countries. There is also a search endpoint to resolve symbols before you query.

Market data is delivered on a 15-minute delayed basis, not a true real-time or tick-level feed. Price history supports intervals from 1-minute up to the full 'max' range, so you can pull intraday bars, multi-year OHLC history, and end-of-day prices from one endpoint. This fits analytics dashboards, backtesting, research, and AI training datasets rather than high-frequency or order-book trading.

You authenticate with an API key, passed either as an HTTP request header or as a query parameter, whichever suits your client. It is a standard REST/JSON API, so any language that can make an HTTPS request works. A dedicated credits endpoint lets you check remaining usage programmatically, and a search endpoint helps you resolve the right ticker before making data calls.

Yes. The Free plan costs $0 and includes 100 API calls per day, enough to evaluate data quality and integration. The Starter plan is $99/month for 1,000,000 successful calls on pay-per-success billing, so failed requests are not counted against you. Enterprise pricing is custom for higher volumes and dedicated support. No tier requires an upfront commitment to test the API.

Yes, and these are the API's strongest assets. Fundamentals include balance sheet and income statement data, while analyst endpoints return earnings estimates and history, EPS trend and revisions, growth estimates, revenue estimate, recommendations, and upgrades/downgrades. Separately, the economic indicators endpoint covers 150+ countries, letting you combine company-level financials with macro context in a single integration.
