Overview
CEOBuySell is a financial data platform that aggregates publicly filed insider transactions, global IPO calendars, and stock fundamentals from official sources. It delivers this data through a searchable web interface and a REST API designed for integration into research workflows and quantitative systems.
The platform tracks insider buying and selling activity — transactions that corporate executives, directors, and major shareholders are required to disclose publicly. Users can filter these transactions by stock symbol, executive name, role, transaction type, and geographic region. The API's parameterized design lets analysts query for specific patterns, such as clusters of insider purchases by C-suite executives in a particular sector, rather than relying on aggregate insider-sentiment metrics alone.
Alongside insider data, CEOBuySell maintains a global IPO calendar with filtering by region, sector, and filing status. This supports investors who want to monitor new listing opportunities as they enter the pipeline across different markets. Stock fundamentals sourced from official disclosures round out the data offering, providing context for insider activity.
Access begins with a free trial that requires no credit card and provides 30 days of recent data. Paid subscription tiers unlock full historical data, export capabilities, and API access. The REST API uses JSON over HTTPS with standard X-API-Key header authentication. Key management happens through a user dashboard, and all API requests are logged. Rate limits scale with the subscription tier, accommodating both evaluation and production workloads.
For developers and quantitative analysts, the API exposes documented endpoints: GET /api/v1/insiders for querying insider transactions with parameters including symbol, executive, role, type, region, and pagination controls, and GET /api/v1/ipos for IPO data filtered by region, sector, and status.
CEOBuySell fits within the broader AI Investing Tools category as a specialized data provider. Unlike AI-driven analysis tools such as TraderGPT, it focuses on raw data aggregation and API delivery rather than generating trade recommendations or natural-language insights. Users seeking automated analysis may consider Laika AI as a complementary tool for AI-powered interpretation of the data CEOBuySell provides.
The platform's value depends on the timeliness and accuracy of the underlying public filing data. While the vendor states data is sourced from official filings, users should verify data freshness against primary sources for time-sensitive trading decisions. The 30-day data window on the free tier is sufficient for evaluation but limits historical analysis without a paid subscription. Teams building production integrations will need to confirm that rate limits at their target tier accommodate their query volume and latency requirements.
