Capabilities
Profile, quotes, and holders each take one coin's slug in the key parameter. The coin listing and the modules are market-wide and take a page number or a module name instead.
Returns the coin's name, symbol, category, description, date added, and status, along with project links such as the website, block explorers, source code, and social accounts. See examples
Quotes return the price, percent change from 1 hour to all time, market cap and fully diluted market cap, circulating, total, and max supply, market dominance, rank, and high and low prices from 24 hours to all time, plus 24-hour volume. See examples
One page of the listing, ordered by market-cap rank, with each coin's name, symbol, slug, supply, and price data. Pages run from 1 to 100, meta.total gives the size of the full listing, and each call has a weight of 5. See examples
Returns the total holder count and the number of daily active addresses, plus the top holder addresses with each balance and its share of supply. See examples
Each call returns one market-wide set: global market metrics, trending coins, most-visited coins, newly added coins, top gainers, or top losers. Modules do not take a coin slug. See examples
Shortened examples
Each sample shows a few fields from one response, without the meta block that a live call also returns. The docs show the full response for each endpoint.

If you do not know a coin's slug, find it in the coin listing. Pass that slug to quotes for a price row, and to profile or holders when a coin page needs them. Market-wide screens such as trending coins or top gainers come from modules, with no slug at all.
The crypto docs cover all five endpoints: the slug that profile, quotes, and holders take, the page range for the coin listing, the six module names, and a sample response for each.
Every endpoint in the documentation includes a sample request in Shell, JavaScript, PHP, and Python.

Coin calls and market-wide calls are separate, so each screen requests only what it shows.

* Overage is optional and stays off until you turn it on in Billing. It is available on paid plans billed by card through Stripe, and not during a trial. Usage is counted in monthly periods that start on your billing day, yearly plans included. Requests past the included limit are charged at the plan's rate for each started block of 1,000, up to the overage cap, on one invoice after the period ends. Amounts under $0.50 carry over to the next invoice. If you change plans during a period, the limit and overage rate of the plan you are on when the period ends apply to the whole period.
The Free plan is also capped at 20 requests per day (New York time). Requests count by endpoint weight, and only responses with HTTP status 200 count.
Commercial use is included only on the plans that list it. If you are not sure whether your project counts as commercial use, email [email protected] before you launch.
