Endpoints are accessed exclusively via secure HTTP `GET` requests, passing your `api_key` as a URL query parameter. `https://data.businessquant.com` ## Supported Asset Classes The API covers three asset classes, each queryable by its native identifier — no conversion required. US macroeconomic indicators are also available, keyed by indicator code rather than by security identifier, through the [Economic Data API](https://businessquant.com/docs/api/economic-data). **Stocks** All US-listed equities traded on NYSE, Nasdaq, and OTC markets. Query by `ticker` or SEC `CIK`. Covers domestic companies and foreign private issuers filing 20-F or 40-F. **Mutual Funds** Registered open-end funds reporting to the SEC. Query by `Series ID` for dividend history, profile data, and ownership records. Includes income, money-market, and bond funds. **ETFs** Exchange-traded funds registered under the Investment Company Act. Query by `ticker` or `Series ID` for dividend yields, institutional ownership, and profile metadata. ## Explore the API Endpoints Select an endpoint below to view its available parameters, authentication requirements, and standard JSON response formats.

Codes in the `2xx` range indicate success. Codes in the `4xx` range indicate a client-side error (missing parameters, invalid API key, resource not found). Codes in the `5xx` range indicate an issue with our backend servers. HTTP Code Error Title Description & Resolution `200` OK The request was completely successful and the requested JSON payload is returned. `400` Bad Request The request was unacceptable. This typically happens if you omitted a required parameter, provided invalid formatting (e.g., a bad date string), or provided conflicting filters. `401` Unauthorized No valid API key provided. Ensure you are successfully appending your `api_key` as a URL query parameter to the request. `403` Forbidden The API key is valid, but your account lacks permissions to access the requested endpoint, or your subscription tier limits access to this specific module. `404` Not Found The requested resource does not exist. This commonly occurs if you pass an invalid, unknown, or delisted `ticker`, or an incorrect SEC `accession` number. `422` Unprocessable Entity A parameter was passed but failed schema validation (e.g., passing a string into an integer-only field like `limit` or `page`). `429` Too Many Requests You have exceeded your account's rate limit or your total monthly API quota. Please slow down your request volume or upgrade your subscription tier. `500` Internal Server Error An unexpected issue occurred on our backend infrastructure. These errors are logged and monitored actively by our engineering team. ## Frequently Asked Questions Common questions about the Business Quant Fundamental Data API. ### Is this fundamental data API free to use? Yes. The Business Quant Fundamental Data API is free to use. Sign up to receive an API key and start pulling financial statements, SEC filings, segment data, insider transactions, analyst estimates, price history, screener results, and economic time-series immediately — no credit card required. ### What asset classes does the API cover? The API covers US-listed stocks, mutual funds, and ETFs. Stocks and ETFs are queryable by ticker symbol or SEC Central Index Key (CIK). Mutual funds are queryable by ticker, CIK, or Series ID. Foreign private issuers trading on US exchanges and filing 20-F or 40-F reports are also supported. ### Where does the financial data come from? All data is sourced directly from SEC EDGAR — the official filing system for US public companies. Financial statements are parsed from 10-K and 10-Q filings, insider transactions from Form 4, and institutional ownership from Form 13F. Data is updated within minutes of each filing being accepted by EDGAR. ### What types of fundamental data can I access? The API provides income statements, balance sheets, cash flow statements, pre-calculated financial ratios, segment revenue and operating income breakdowns, geographic revenue data, Wall Street analyst consensus estimates, historical dividend payments and daily yield time-series, insider transaction records, and institutional 13F ownership data. Alongside those fundamentals it also serves end-of-day and intraday price history, real-time streaming quotes, full-market screening, corporate actions, item-level SEC filing sections, the complete securities universe, and US macroeconomic indicators with their release calendar — all from one API key. ### Does the API include economic and macroeconomic data? Yes. The [Economic Data API](https://businessquant.com/docs/api/economic-data) serves historical time-series for US macro indicators including GDP, CPI and inflation, the unemployment rate, interest rates, housing starts, retail sales, and industrial production — each with descriptors for release frequency, seasonal adjustment, unit, and precision. Four transformation modes let the API return raw levels, percentage change rebased to your window, drawdown from a running high, or gain from a running low. The [Economic Indicators List API](https://businessquant.com/docs/api/economic-list) returns the full catalog of codes, and the [Economic Calendar API](https://businessquant.com/docs/api/economic-calendar) covers release schedules and the latest prints. ### How do I authenticate requests to the API? Authentication is done by appending your `api_key` as a URL query parameter on every GET request — for example: `?ticker=AAPL&api_key=YOUR_KEY`. Obtain your key by registering for free.
