Vendor claims data aggregation from publicly filed official sources. API documentation is clear and versioned with specific parameter schemas. Data freshness and accuracy cannot be independently verified from the source packet alone.

Homepage states aggregation from publicly filed insider transactions and official sources. API reference documents specific endpoints with parameter schemas and example curl requests.

Standard REST patterns, JSON responses, and header-based authentication are familiar to most developers. Dashboard-based key management is straightforward. No SDK or client library references found in available documentation, which may require additional integration effort.

API docs specify JSON over HTTPS with X-API-Key header authentication. Keys are generated from a user dashboard. Endpoint documentation includes parameter tables and example requests.

Three data domains — insider transactions, IPOs, and fundamentals — with filterable parameters and pagination. No evidence of visualization, alerting, screening, backtesting, or analysis features in the available source material. Positioned as a data provider rather than an analysis platform.

API exposes insiders and IPOs endpoints with multi-parameter filtering and pagination. Stock fundamentals are mentioned on the homepage without a dedicated endpoint documented in the available API reference.

API-first design with paginated, parameterized endpoints supports integration into quantitative workflows and research pipelines. JSON output is machine-readable. Tiered rate limiting accommodates scaling from evaluation to production. No webhook or streaming support evident.

Endpoints support pagination via page and limit parameters plus filtering by symbol, executive, role, type, region, sector, and status. Tiered rate limits allow capacity planning by subscription level.

Audit logging of all API requests provides operational visibility and accountability. No uptime SLA, status page reference, redundancy architecture, or data-delivery guarantee found in the available source packet. Reliability assessment is necessarily conservative.

API documentation states all requests are logged. Rate limiting is documented by subscription tier. No additional reliability or availability commitments found.

Free no-credit-card trial allows risk-free evaluation of the platform's data coverage and API quality. Specific pricing for paid tiers is not disclosed in the source packet, preventing a complete value assessment. The 30-day data window on the free tier provides limited utility for historical analysis.

Homepage offers free trial with no credit card required. Upgrade path is mentioned for full history, exports, and API access, but tier pricing is not specified.
