Create some tools

Hi aavegotchi coders !

I would know if some king ppl who be able to create some tools like :

an indicator of how many portals from the 10 000 first batch have been opened
an indicator of how many legendary aavegotchi have been found
an historic of wearable, consumable and portal price transaction in order to create a “fairmarket” help buyer and seller to fixe the right price.

thank’s !
