Account progress for weekly fractals

[Tesche.5423]

Hello everyone! I'm trying to write an application that tells me which fractals I should do to finish my weekly achievements (it wouldn't show me fractals that I have done already, nor the ones that are recommended for the week). But I wasn't able to find my account progress for them anywhere on the API; already found their ids (5453, 5441, 5448, if you're interested), but they're not listed on the v2/account/achievements page. I'd greatly appreciate if anyone could help me with that.
As a bonus, if someone also knows if it's possible to get the 15-days rotation for recommended fractals from the API, that would be awesome, I'll just copy the table from the wiki if it's not, though.

Thank you for reading!

Dang this topic is old , well I also got this far atm ... 

I guess need to recreate the system

I also want to make this, but there seems to be an issue with the JSON about this achievement.
If I use: https://api.guildwars2.com/v2/achievements?ids=5453,5441,5448

All I get is the raw text and there are no attributes to state if a given fractile has been done or not.  And if I try and tag an API account key to it there is no chance of what the JSON provides.
If I go on: https://gw2efficiency.com/account/achievements <- and look at fractal weekly it is also not updating right.  And this is the go-to site for this sort of thing, so I think something changed the JSON at some point.

Anyway hope someone looks into this.  If poke me I don't mind trying to make this.

-----

Small edit: I made this as far as possible without account key information.  This spreadsheet will show what the current week's Recs and dailies are for all tiers, so you can determine yourself which ones should be doing weekly.  Hope this helps.
