Sure, but the API itself is the easy part, especially with LLM help. The problem is the data source is a total trash fire, so in order for it to be worth it the API cost would either be exorbitant or not worth it.
I run a web service whose primary purpose is cleaning up messy, SEO-enshittified data from Google, eBay, etc. After years of fine-tuning my own heuristics, I threw a super-cheap LLM at it and it massively out-performed my custom code. It's slower, but the results are well worth it.
