CoinMarketCal tools (7)

write = sends, deletes, buys or posts
  • get_coinFree

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

  • get_eventFree

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 An unknown, temporarily unpublished, or out-of-window event returns `404`.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

    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_categoriesFree

    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_coinsFree

    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_cancellationsFree

    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_eventsFree

    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`.

CoinMarketCal API

Official examples for the CoinMarketCal API and MCP server.

CoinMarketCal is a crypto events calendar. Each event has a date, the coins it affects, an editorial category, an impact score and the source it comes from. The same data is available through a REST API and an MCP server for AI agents.

  • Get an API key: coinmarketcal.com/developer (free tier available)
  • Documentation: coinmarketcal.com/developer/docs
  • OpenAPI spec: openapi.json
  • MCP server: https://coinmarketcal.com/mcp (setup guide, MCP Registry: com.coinmarketcal/events)

Quick start

Every request sends your key in the x-api-key header.

curl -s "https://api.coinmarketcal.com/v2/events?coins=ethereum&limit=5" \
  -H "x-api-key: $COINMARKETCAL_API_KEY"

Each event looks like this (fields depend on your plan):

{
  "id": "48291",
  "slug": "ethereum-pectra-upgrade",
  "title": "Ethereum Pectra Upgrade",
  "date": "2026-05-06T12:00:00Z",
  "dateType": "date",
  "isEstimated": false,
  "displayedDate": "06 May 2026",
  "categories": ["Release"],
  "coins": [{ "slug": "ethereum", "symbol": "eth", "name": "Ethereum" }],
  "impact": 8.5
}

When isEstimated is true, date is a deadline or the end of a window, not an exact day. Show displayedDate to your users (for example Q2 2026 or By 30 May 2026).

Use it from an AI agent (MCP)

The MCP server exposes the read endpoints of the API as tools (listevents, getevent, list_coins, …). Event results include the url of the event page on coinmarketcal.com. It uses the same key and quota as the REST API.
