    Description, as the server wrote it
    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.

    Description, as the server wrote it

  • list_event_cancellationsReturns removal records ordered by `cancelledAt`, then `id`.No findings

    Why it is in this group

    • The name "list_event_cancellations" says "list": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "list_events" says "list": a word for reading.
    Description, as the server wrote it
    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`.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
