Netzhandwerker Agent Tools /v1/cohort/retention APIPOST /v1/cohort/retention · x402 API by Netzhandwerker Agent Tools

Builds the cohort table from the events you pass: users grouped by the period of their first event, counted again in each following period. Returns the table per cohort, a retention curve across all cohorts, and, where events carry a value, cumulative value and value per user. The curve counts only cohorts old enough for a given period, so a young cohort is not scored as churn. Day, week and month are real calendar periods. Nothing is fetched, nothing is stored.
