Finance
Polygon is an API listed in the Finance category that provides access to historical stock market data. It is intended for developers who want to integrate this type of finance data or functionality into websites, mobile applications, dashboards, automation workflows, research projects, prototypes, or backend services without building the underlying data source or service from scratch. From the supplied API metadata, the supplied listing identifies apiKey as the authentication method; HTTPS support is listed as available. This makes Polygon a useful integration candidate when a project needs historical stock market data through a programmatic interface. Because API capabilities, quotas, authentication rules, endpoints, and availability can change over time, the provider documentation should be treated as the current technical reference.
