GET https://circleci.com/api/v2/insights/{project-slug}/flaky-tests with header 'Circle-Token: $CIRCLE_TOKEN' to list flaky tests - tests that both passed and failed in the same commit; results are branch-agnostic.
Flaky-test metrics are calculated from the project's 10 most recent workflow runs, not a configurable date range.
GET https://circleci.com/api/v2/insights/{project-slug}/workflows with header 'Circle-Token: $CIRCLE_TOKEN' to list summary success-rate/duration/credit-usage metrics per workflow name in the project.
Add query parameter reporting-window (e.g. ?reporting-window=last-30-days) to control the aggregation period for the workflows summary endpoint. Allowed values: last-24-hours, last-7-days, last-30-days, last-60-days, last-90-days; defaults to last-90-days if omitted.
GET https://circleci.com/api/v2/insights/{project-slug}/workflows/{workflow-name}/test-metrics with header 'Circle-Token: $CIRCLE_TOKEN' for per-workflow test metrics including most_failed_tests and slowest_tests.
flaky-tests is based on the 10 most recent workflow runs only - reporting-window does not apply to it (that parameter belongs to the workflows summary-metrics endpoint).
Insights endpoints key off project-slug (vcs-type/org/project) rather than a workflow id.
