# Introduction

> Based in NYC, we build market infrastructure for agents.

Financial Datasets lets you easily connect your agent to real-time, structured financial data - fundamentals, filings, ownership, earnings, KPIs, and more - using our clean, predictable APIs.

New data hits the API within seconds of publication.  We are a [primary-source provider](/data-provenance) of SEC data: statements, filings, and disclosures are collected, parsed, and served by us directly.

## What You Can Access

We cover **27,000+ active and delisted US tickers** with **30+ years** of history. Core datasets include:

* **[Activist Ownership](/api/activist-ownership)** - Schedule 13D activist stakes, within a minute of hitting EDGAR.
* **[Beneficial Ownership](/api/beneficial-ownership)** - Every 5%+ holder, activist and passive, from Schedules 13D and 13G.
* **[Earnings Data](/api/earnings)** - Structured quarterly and annual results, estimates, and surprise flags.
* **[Financial Statements](/api/financials/income-statements)** - Income statements, balance sheets, and cash flow statements.
* **[Index Funds](/api/index-funds/ticker)** - ETF and index-fund holdings, weights, and which funds hold a security.
* **[Insider Ownership](/api/insider-ownership)** - Form 3 and Form 5 ownership statements - what insiders actually hold.
* **[Insider Trades](/api/insider-trades)** - Form 4 and Form 5 insider activity.
* **[Institutional Holdings](/api/institutional-holdings/investor)** - SEC-direct Form 13F institutional holdings.
* **[Macroeconomics](/api/macro/yield-curve/snapshot)** - Treasury yields, consumer price inflation, and central bank policy rates.
* **[Operational KPIs](/api/kpi/metrics)** - KPI metrics, forward guidance, and non-GAAP metrics.
* **[SEC Filings](/api/filings/ticker)** - 10-K, 10-Q, 8-K, and more - with access to specific sections (e.g. Item 1A, Item 7).
* **[Segmented Financials](/api/financials/income-statement-segments)** - Business segment and geographic breakdowns.
* **[Stock Prices](/api/prices/historical)** - Real-time and historical equity price data.

## Data Formats

* **Structured** - clean, typed JSON with consistent field naming across every endpoint.
* **Unstructured** - raw filing text and full documents, including section-level access to SEC filings.
* **Normalized / standardized** - line items mapped to a consistent taxonomy so they're comparable across companies and time periods.
* **As-reported** - figures exactly as the company filed them, preserving original labels and values without standardization.

## Built For

* AI financial agents and LLM pipelines
* Quantitative research platforms
* Portfolio management systems
* Event-driven trading infrastructure
* Internal data layers for fintech products

## Design Principles

* **Real-time ingestion** - filings are processed within seconds of publication.
* **Structured JSON responses** - consistent field naming across all endpoints.
* **Section-level filing access** - query specific sections of SEC filings without parsing full documents.
* **Machine-first design** - optimized for programmatic consumption, not human browsing.
