About AlphaSMO
AlphaSMO provides a REST API for accessing compiled institutional and insider trading data, including 13F filings, Form 4 filings, 13D/13G filings, and 8-K events. The API exposes endpoints for listing and retrieving institution details and holdings, stock-level detail and flow data, insider trading activity by ticker, and a smart-money convergence endpoint that surfaces overlapping institutional and insider activity signals.
The API is available anonymously by IP address at a lower rate limit, with no signup required to start making requests. An API key can be obtained to raise the rate limit, passed via an X-API-Key header on requests.
This service is aimed at developers building applications or analysis tools that need programmatic access to aggregated 13F, Form 4, 13D/13G, and 8-K filing data, as well as derived signals such as smart money convergence and stock buy/sell flow trends.
