API - get token migration / redenomination data for owned coin

Hi.

Is there a way to fetch relevant data like token migration / redenomination for coins I own through the API? I would like to link between old balance I had / the old coin name and the new data for it.

Some examples I tried to find data about -

I owned COCOS right before it had redenomination of 1000:1
I couldn’t find any endpoint that actually tells me about the change to my owned asset.
I searched this data in the exported transactions history csv and found one row with a “Distribution” action that has a negative Change value. But it doesn’t really explain anything on why. (Tax engines thought it was transferred to someone else from my account and saw it as a taxable event)
I tried using /sapi/v1/asset/assetDividend which didn’t list anything about it.

Another example is Pundi X (NPXS) Token Migration & Redenomination Plan
I owned NPXS, and got 1000:1 PUNDIX.
In that case /sapi/v1/asset/assetDividend only gives me details about getting PUNDIX (a positive change), but nothing about NPXS. I would really want to know about that “name” change and the old and new amounts.
In the exported transactions history csv, there are 2 Distribution actions, one with a negative change for NPXS and one for positive of PUNDIX (without really being able to connect the two) - does at least the negative change appear anywhere in the API?

Final example is DREP (DREP) 100:1 Redenomination Plan
Again, I owned DREP, and through/sapi/v1/asset/assetDividend I only got the final amount, but nothing about the ratio.
I can’t really infer anything from that, because I had a similar row for PUNDIX, but there was also a name change there. I can’t really assume that the new amount replaced the old amount for the same coin name without any extra data.
In the transactions history csv there were 2 lines of negative change and a positive change, and comparing that to COCOS again makes no sense, because COCOS did not have a positive change row, only the negative one. (why is there a difference between the both?)

So as far as I can understand, there are inconsistencies even in the csv file, which does give somewhat more information.
I tried looking it up in the forums, but couldn’t find anything similar.

Thanks in advance for any assistance.
