Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (7)

`get_coin`	Returns the full coin payload by slug. 404 when the slug doesn't match any coin (tracked or otherwise).
`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 An unknown, temporarily unpublished, or out-of-window event returns `404`.
`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.
`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.
`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.
`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`.

Schemas: list_tools.
