What's the URL for this particular NFT?

The info is linked to from here:

https://foundation.app/DisasterGirl/disaster-girl-25046

Here's the token:

https://etherscan.io/token/0x3b3ee1931dc30c1957379fac9aba94d...

What's burned into the blockchain is the URL of a JSON file which is hosted on IPFS:

https://ipfs.io/ipfs/QmYBvcJMaYFrUwhTRcbiHqFBoYPP54t4aBCnk1K...

That in turn points to the image, also hosted on IPFS:

https://ipfs.io/ipfs/QmeQ6c5HdnEDcheHmWuKWdwMHBBZg1eGpgV5h3H...

Here's the transaction which minted the token with the IPFS URL of the metadata as input:

https://etherscan.io/tx/0xccc3f7ee08307dd469af7c65c55e087edc...

As to NFTs themselves, you’ll have to understand Etherium smart contracts. This particular NFT is a Foundation NFT which implements the ERC-721 interface:

(Except the underlying contract actually appears to be https://docs.zeppelinos.org/docs/1.0.0/upgradeability_adminu... which I understand to be a contract that proxies its implantation. I’m not entirely clear how that works.)
