Results come back in input order, one per item: id exactly as sent (null when not sent), q, status, cp7 and suggestion. status 'ok' — the postal code was determined and is in cp7; 'ambiguous' — no single answer (several candidates with nothing to tell them apart, a street with several postal codes and no door number, or just a locality): cp7 is null and suggestion is the best candidate for a person to confirm; 'not_found' — nothing matched: suggestion is null. suggestion has the same shape as a suggest_address suggestion.
