How can i get the instanceSlug from an NFT Address?

I want to get the same data i did get by calling https://apps.api.manifoldxyz.dev/public/instance/data?appId=2522713783&instanceSlug=NyanBalloon with the nft contract address i.e. take in an address and if valid get the same info i get from the instanceSlug. I have queried the contracts metadata or reads method on etherscan, to see if there is any way i could link a metadata to an instance slug, this hasn’t been successful.

What is the suggested way to get an instance slug from a contract address ? or the name in the metadata field ? (Api docs dont exist for claims any longer)

Or if i can go from contract address to → instanceSlug to → data (it’s still fine).
