list_events Returns a paginated list of upcoming and historical events within the date window available to the caller's plan. Default sort is `date asc` (soonest first). The `coins`, `categories`, and date filters compose with `AND`.
list_event_cancellations Returns removal records ordered by `cancelledAt`, then `id`. Available to every API V2 tier. Poll regularly and never leave more than 90 days between successful requests, even when webhooks are enabled.
get_event Returns the full event payload by id. Tier-gated fields follow the caller's plan. A recently removed event returns `410 Gone` with its `id` and `cancelledAt`. An unknown, temporarily unpublished, or out-of-window event returns `404`.
list_categories Returns every category in the editorial taxonomy with the count of upcoming events per category (tier-windowed). Standard+ only. Query parameters are ignored; the list is not paginated.
list_coins Returns a paginated list of coins ordered by `rank` ascending (top-ranked first). Pass the `tracked` filter only when you need to limit results by editorial coverage.
get_coin Returns the full coin payload by slug. 404 when the slug doesn't match any coin (tracked or otherwise).
get_usage Returns the authenticated key's monthly usage counters. Does not consume quota beyond the cost of the HTTP call itself. Use this to backoff before hitting 429s or to drive alerts in your integration.
