+ * You can wrap your calls to an API provider with the
+ * {@see ApiProvider::resolve} method to ensure that API data is created. If the

+ *     // Returns an array or throws.
+ *     $data = ApiProvider::resolve($provider, 'api', 'elasticfood', '2020-01-01');
+ *
+ * You can compose multiple providers into a single provider using
+ * {@see Aws\or_chain}. This method accepts providers as arguments and
+ * returns a new function that will invoke each provider until a non-null value
+ * is returned.
