JSON Array to Javascript for use in a Mapkit JS map

Question

Sorry if this is answered somewhere but I have genuinely looked everywhere. I'm pretty useless at Javascript, just can't wrap my head around it.

I've pulled information from my CRM's API run json_decode and the JSON array that looks like this.

Array
(
[parties] => Array
    (
        [0] => Array
            (
                [id] => 223456351
                [owner] => 
                [team] => 
                [type] => organisation
                [about] => 
                [name] => ACME Inc
                [createdAt] => 2022-03-15T14:10:46Z
                [updatedAt] => 2022-04-01T13:58:35Z
                [lastContactedAt] => 2022-03-15T14:19:11Z
                [pictureURL] => 
                [phoneNumbers] => Array
                    (
                    )

                [addresses] => Array
                    (
                        [0] => Array
                            (
                                [id] => 49336420
                                [type] => 
                                [city] => New York
                                [country] => 
                                [street] => Broadway,
                                [state] => 
                                [zip] => 10004
                            )

                    )

                [emailAddresses] => Array
                    (
                    )

                [websites] => Array
                    (
                    )

            )

        [1] => Array
            (
                [id] => 226323207
                [owner] => 
                [team] => 
                [type] => organisation
                [about] => 
                [name] => Wayne Enterprises
                [createdAt] => 2022-02-08T14:21:35Z
                [updatedAt] => 2022-04-01T14:01:19Z
                [lastContactedAt] => 2022-02-08T15:56:59Z
                [pictureURL] => 
                [phoneNumbers] => Array
                    (
                    )

                [addresses] => Array
                    (
                        [0] => Array
                            (
                                [id] => 493532394
                                [type] => 
                                [city] => New York
                                [country] => 
                                [street] => Broadway,
                                [state] => 
                                [zip] => 10004
                            )

                    )

                [emailAddresses] => Array
                    (
                    )

                [websites] => Array
                    (
                    )

            )

I would like to cycle through the 'zip' field to make annotations in Mapkit JS like below. And this is where I'm stuck I cannot for the life of me work out how to use a foreach or similar or pull the information.

       let geocoder = new mapkit.Geocoder();
   geocoder.lookup("ZIPHERE", (error, data) => {
     if (error) {
       return;
     }
     map.addAnnotation(new mapkit.MarkerAnnotation(data.results[0].coordinate));
   });

Any help would be amazing.
