Address Completion API

Address completion API for mainland China. It fills in incomplete mainland China addresses — usually a missing administrative district — and corrects malformed ones. Use it to preprocess customer addresses before a streamer ships a batch of orders. It wraps Alibaba Cloud's address standardization service, and a thousand-guard batch (1,000 addresses) costs only 6 CNY to process

It already runs on Subspace Shop, completing addresses automatically as orders are created and saving considerable time otherwise spent correcting them
