CoinMarketCap API Client for WordPress
======================================

[](#coinmarketcap-api-client-for-wordpress)

A PHP client for fetching data from the [CoinMarketCap Pro Cryptocurrency API](https://pro.coinmarketcap.com/api/documentation/pro-api-reference/cryptocurrency) endpoint intended to be used in WordPress plugins or themes. Being a good WordPress citizen, this client uses the WordPress core [HTTP API](https://developer.wordpress.org/plugins/http-api/) to fetch its data.

Note that this package only covers the Cryptocurrency endpoint family, with the addition of the [Key Info](https://pro.coinmarketcap.com/api/documentation/pro-api-reference/cryptocurrency) endpoint for use as a health probe.

Use
---

[](#use)

Include the main `class-client.php` file and create an instance of the `Client` class and use its methods to fetch data from the CoinMarketCap API. Each method maps to one of the [Implemented endpoints](#implemented-endpoints) listed above and will either return the decoded response body as an array or a [WP\_Error](https://developer.wordpress.org/reference/classes/wp_error/) object. Note that access to the CoinMarketCap API requires an API key.

```
require_once '/your/cool/path/to/coinmarketcap-client/class-client.php';

/*
 * There are two ways the Client class can use your CoinMarketCap API key:
 *
 * - Pass the API key to the Client class directly like in the example below.
 * - Define a global COINMARKETCAP_API_KEY constant.
 */
$client = new Cointokio\CoinMarketCap\Client( 'your-api-key' );

/*
 * Use the key()->get_info() method to inspect the configured API key
 * (does not consume call credits).
 *
 * @see https://pro.coinmarketcap.com/api/documentation/pro-api-reference/tools/key-info
 */
$response = $client->key()->get_info();

```

The following example uses the `$client->cryptocurrency()->quotes_latest()` method to fetch data from the `/v3/cryptocurrency/quotes/latest` endpoint.

```
require_once '/your/cool/path/to/coinmarketcap-client/class-client.php';

$client = new Cointokio\CoinMarketCap\Client( 'your-api-key' );

/*
 * Get the latest market quote for one or more cryptocurrencies. The
 * `convert` argument bundles multiple fiat conversions into a single call.
 *
 * @see https://pro.coinmarketcap.com/api/documentation/pro-api-reference/cryptocurrency/cryptocurrency-quotes-latest
 *
 * Note that the $client->cryptocurrency() method returns an instance of the
 * \Cointokio\CoinMarketCap\Cryptocurrency class. This allows us to use the
 * Cryptocurrency class methods more easily via method chaining, eg.:
 *
 * $client->cryptocurrency()->quotes_latest()
 *
 * @see https://en.wikipedia.org/wiki/Method_chaining
 */
$response = $client->cryptocurrency()->quotes_latest( '1,1027', 'USD,EUR' );

```

### `convert` limit

[](#convert-limit)

Every CoinMarketCap plan caps the number of `convert` values accepted per `quotes/latest` request, with the free Basic plan capped at one. Bundling more than the per-plan cap into a single call is rejected with a `400` ("Your plan is limited to N convert options"), surfaced by the client as `WP_Error( 'http_400', ... )`. To stay portable across plan tiers, issue one `quotes_latest()` request per fiat:

```
foreach ( $fiats as $fiat ) {
    $response = $client->cryptocurrency()->quotes_latest( $ids_csv, $fiat );
    // Aggregate per-fiat responses into your own structure.
}

```
