All access to MERMAID data, including that done by mermaidr, the MERMAID web application, and the dashboard, is done through an Application Programming Interface (API). If you need custom access to data, for example because you are creating a map or writing your own tool, you can use API documentation here as a guide. The documentation includes a getting started page on how to use the Insomnia API client file included with the MERMAID API code repository to access all API endpoints.
