Context tax

Connecting this server adds ~1,238 tokens of tool definitions to every model turn (moderate, 7 tools). Measured 2026-10-19 via its hosted endpoint; o200k tokenizer, worst case for clients that load all tools up front. How we measure

Input prices as of 2026-10-06. Excludes your own prompt and output.

Tools (7)

• list_events476 tok

  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_coins178 tok

  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_cancellations162 tok

  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_event122 tok

  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 An unknown, temporarily unpublished, or out-of-window event returns `404`.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_coin91 tok

  Returns the full coin payload by slug. 404 when the slug doesn't match any coin (tracked or otherwise).

• get_usage76 tok

  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_categories72 tok

  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.
