The endpoint is given in the query because templates contain slashes. Sessions that hit it: /sessions or /cohorts/compare with endpoint_method, endpoint_host and endpoint_template. ## OpenAPI ````yaml /api-reference/openapi.json get /projects/{projectId}/network/endpoints/detail openapi: 3.1.0 info: title: Apsio API version: 0.1.0 description: >- Read API v0: your projects, release health and comparisons, missing symbols, issues, sessions, vitals, cohort comparisons, performance (app start, screens, hangs, MetricKit) and network endpoints and traces for one project.
