Handling JSON response from cURL - php

Question

I am trying to get data from an address verification API I use, and I'm having trouble getting data from it. I have no problem cURLing the addresses and getting a response, but I need help with PHP handling the response.
JSON structure:
[
{ "input_index": 0,
"candidate_index": 0,
"addressee": "Apple Inc",
"delivery_line_1": "1 Infinite Loop",
"delivery_line_2": "PO Box 42",
"last_line": "Cupertino CA 95014-2083",
"delivery_point_barcode": "950142083017",
"metadata": {
"latitude":"48.12685",
"longitude":"-39.16847"
},
}
{ "input_index": 1,
"candidate_index": 0,
"addressee": "Google Inc",
"delivery_line_1": "1600 Amphitheater Pkwy",
"delivery_line_2": "",
"last_line": "Mountain View CA 94043-1351",
"delivery_point_barcode": "950142083017",
"metadata": {
"latitude":"48.12685",
"longitude":"-39.16847"
},
}
]
My code:
$response = curl_exec($ch);
curl_close($ch);
$rd = json_decode($response);
echo $rd->metadata[0]->latitude;
But then I get the error of Trying to get property of non-object.
What am I doing wrong?
EDIT:
print_r($rd); gives me:

Invalid JSON:
"metadata": {
"latitude":"48.12685",
"longitude":"-39.16847
} ...
should be:
"metadata": {
"latitude":"48.12685",
"longitude":"-39.16847"
} ...
Mind the closing " on the longitude value.
furthermore, the two entries need to be separated by ,:
[
{ "input_index": 0,
...
},
{ "input_index": 1,
...
}
]
finally: what you get is an array of objects - not an object with arrays:
$rd[0]->metadata->latitude ...
