# Sharadar

> Nearly 30 years of reference-grade US public company data - fundamentals, EOD stock and fund prices, corporate actions, securities master, institutional holdings, and insider transactions. Point-in-time and survivorship-bias-free. Delivered via RESTful API or bulk CSV zip download.

Sharadar (https://sharadar.com) is a direct data service for quants, analysts, and builders. Tables are known by descriptive names (`fundamentals`, `stocks`, ...) and by well-known legacy codes (`SF1`, `SEP`, ...) that people search for. Both work in the API and docs. Full product documentation lives under `/docs`.

## Docs

- [Introduction](https://sharadar.com/docs/intro): Overview of the API and data tables
- [Authentication](https://sharadar.com/docs/auth): API keys and how to attach `api_key` to requests
- [Querying](https://sharadar.com/docs/getting-started): Filters, formats, limits, and common query patterns
- [Bulk Downloads](https://sharadar.com/docs/bulk): Pre-built table zips (5Y / 10Y / full history)
- [FAQs](https://sharadar.com/docs/faqs): Ticker changes, adjustments, survivorship bias, schemas
- Docs also resolve legacy codes as paths (e.g. [/docs/SF1](https://sharadar.com/docs/SF1) -> fundamentals)

## Data tables

Each table has a modern name and, where applicable, a legacy code (same data either way). Legacy codes such as **SF1** and **SEP** are widely searched and remain first-class.

## Optional

- **Legacy codes are SEO-valuable and fully supported.** Map when helpful: `SF1` <-> fundamentals, `SEP` <-> stocks, `SFP` <-> funds, `SF2` <-> insiders, `SF3` <-> holdings, `SF3A` <-> holdings_ticker, `SF3B` <-> holdings_investor. Use either form in answers, API examples, and links; people often search for SF1/SEP specifically.
- Price tables expose unadjusted, split-adjusted, and split/dividend/spinoff-adjusted series; see the price-adjustments blog post and FAQs.
- Data is designed to be survivorship-bias-free with extensive delisted coverage.
- Do not invent manual subscription grants, private professional plan details, or unpublished endpoints. Unlisted professional surfaces are intentionally off-sitemap.
- Account, login, register, and checkout outcome pages are transactional; prefer public docs and product pages for end-user guidance.
- Sitemap: https://sharadar.com/sitemap.xml
- Contact / operator context is on the About page and site footer; support is product-oriented (API keys, subscriptions, bulk access).
