Since November 2, 2026, the latest crypto prices in the CoinMarketCap API update every 15 seconds, down from every 60 seconds. You don't need a new key, new endpoints or a migration: the calls you already make return fresher data.
Here's what that means in practice. Say your bot asks /v3/cryptocurrency/listings/latest for the price of $BTC every 15 seconds. Until November 1, three of every four calls returned the same price as the call before, because the data only changed once a minute. Now each call can return a new price.
Think of an airport departures board that used to refresh once a minute and now refreshes every 15 seconds. The comparison stops at one point: the board shows a snapshot at each refresh, not every change in between, and some endpoints add a short cache on top. That's why some rates below are a range.
<h2 id="header-0">What updates faster</h2>
Every 15 seconds, down from every 60 seconds:
<ul>
 <li>/v3/cryptocurrency/listings/latest: every active cryptocurrency with its latest price, market cap, volume and percent change</li>
 <li>/v1/cryptocurrency/listings/new: the quotes of the most recently added cryptocurrencies</li>
 <li>/v1/cryptocurrency/category: the quotes of the cryptocurrencies in a category</li>
</ul>
Every 15 to 25 seconds:
<ul>
 <li>/v3/cryptocurrency/quotes/latest: the latest quote for one or more cryptocurrencies (was every 60 seconds)</li>
 <li>/v2/simple/price: a lightweight latest price (was every 60 seconds)</li>
 <li>/v2/cryptocurrency/ohlcv/latest: the close (was every 10 minutes)</li>
 <li>/v1/cryptocurrency/trending/latest, /trending/gainers-losers and /trending/most-visited: the quotes of the coins in each list</li>
</ul>
<h2 id="header-1">Why some rates are a range</h2>
For the endpoints with a range, the data refreshes every 15 seconds and the API keeps each quote in a cache for up to 10 seconds, so the price you receive is at most 25 seconds old.
<h2 id="header-2">Update rates for every endpoint</h2>
The API reference now lists the update rate of every endpoint, so you can match your polling to the data. A few worth knowing:
<ul>
 <li>The /v1/cryptocurrency/trending/gainers-losers list updates every 60 seconds.</li>
 <li>The /v1/cryptocurrency/trending/most-visited list updates every 4 hours.</li>
 <li>The 30d list in /v1/cryptocurrency/trending/latest updates every 12 hours. The default first page (start=1, limit=100, USD) can be up to 10 minutes old.</li>
 <li>open, high, low and volume in /v2/cryptocurrency/ohlcv/latest update every 5 to 7 minutes.</li>
 <li>Category statistics in /v1/cryptocurrency/category and /v1/cryptocurrency/categories update every 5 to 15 minutes.</li>
 <li>Newly added cryptocurrencies usually appear in /v1/cryptocurrency/listings/new within 10 minutes.</li>
</ul>
<h2 id="header-3">What to build with it</h2>
<ul>
 <li>Trading tools and bots can act on a price that's at most 25 seconds old.</li>
 <li>Portfolio trackers can keep balances close to the market all day.</li>
 <li>Price alerts can fire closer to the moment a level is crossed.</li>
 <li>Tickers and widgets on news sites and apps can stay in step with the market.</li>
</ul>
<h2 id="header-4">Questions developers ask</h2>
Do I need to change my code? No. The endpoints, parameters and API key stay the same.
Will polling more often use more credits? Yes. Each call uses credits as listed for its endpoint in the<a target="_blank" rel="noopener noreferrer nofollow" href="https://coinmarketcap.com/api/documentation/pro-api-reference/cryptocurrency"> API reference</a>, so four calls a minute use four times the credits of one. Check your plan's monthly credits before you shorten your interval.
Which endpoints keep their rate? The historical endpoints, /v2/cryptocurrency/market-pairs/latest and /v2/cryptocurrency/price-performance-stats/latest. Their rates are in the API reference.
Where can I check a rate? In the Cache / Update frequency note of each endpoint in the API reference, and in the v3.0.7 changelog.
