# Supplemental API

> Options, stocks, analytics, company data, stock alternative, and more. Supplemental endpoints for research, market data, and fundamentals.

The **Supplemental API** extends the Aries platform with extra data and analytics: options chains, stock aggregates, company profiles, stock alternative data (transcripts, ESG, lobbying, etc.), calendars, and fundamentals. Use these endpoints for research, screening, and enriched market data alongside the [Core API](/api-reference).

<Note>
  **Core vs. Supplemental — which do you need?** The Core API powers essential trading functionality such as retrieving balances and positions, placing orders, and streaming market data. The Supplemental API provides additional market intelligence, including company financials, earnings calendars, news, sentiment, technical patterns, and alternative datasets. Many production trading applications use both APIs together to deliver a more comprehensive trading experience.
