CoinGecko API Client for WordPress

A PHP client for fetching data from the CoinGecko API intended to be used in WordPress plugins or themes. Being a good WordPress citizen, this client uses the WordPress core HTTP API to fetch its data.

Installation

This package is available on packagist.org can be added as a dependency to your project via Composer.

composer require cointokio/coingecko-api-client

Usage

Include the main class-client.php file and create an instance of the Client class and use its methods to fetch data from the CoinGecko API. Each method represents a separate API endpoint and will either return a list of response data or a WP_Error object.

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

$client = new Cointokio\CoinGecko\Client();

/*
 * Use the ping() method to check the CoinGecko API status.
 *
 * @see https://www.coingecko.com/api/documentations/v3#/ping
 */
$response = $client->ping();

The following example uses the $client->coins()->get_markets() method to fetch data from CoinGecko's /coins/markets endpoint:

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

$client = new Cointokio\CoinGecko\Client();

/*
 * Get a list of price, market cap, volume and market-related data.
 *
 * @see https://www.coingecko.com/api/documentations/v3#/coins/get_coins_markets
 *
 * Note that the $client->coins() method returns an instance of the
 * \Cointokio\CoinGecko\Coins class. This allows us to use the Coins class methods
 * more easily via method chaining, eg.:
 *
 * $client->coins()->get_list()
 * $client->coins()->get_markets()
 *
 * @see https://github.com/cointokio/coingecko-api-client/blob/main/class-client.php#L41
 * @see https://github.com/cointokio/coingecko-api-client/blob/main/classes/class-coins.php
 * @see https://en.wikipedia.org/wiki/Method_chaining
 */
$response = $client->coins()->get_markets(
	'eur',
	array( 'ids' => 'btc, eth' )
);
