There are some awesome APIs that index/aggregate on-chain data across multiple chains that you can use too. I would generally recommend these over the exchange APIs.https://glacier-api.avax.network/apihttps://thegraph.com/en/https://docs.alchemy.com/reference/api-overview. Source: about 1 year ago

When it comes to indexing solutions, you can use The Graph; a decentralized solution, and again use Nader's resources to learn how to get started:. - Source: dev.to / over 1 year ago

Alternatively if you do want to go the third party data route, there are a number of saas type offerings on the market - thegraph was once pretty popular (https://thegraph.com/en/) they provide a graphql interface for querying data. Source: over 1 year ago

To take Beeple's $69M NFT as an example, its JSON metadata points us to an IPFS gateway run by http://makersplace.com. Source: about 2 years ago

In theory, but if the hashed file is a JSON that contains a link for the media source of "ipfsgateway.makersplace.com/[UNIQUE STRING]", and makersplace.com goes under, wouldn't it be very challenging to recover the actual file stored on the p2p network and update the embedded link?

Most IPFS hash's return a JSON file that contains a link to an IPFS gateway that is hosted by the company that minted the NFT. Sure this type may not expire on its own, but if makersplace.com goes under, ipfsgateway.makersplace.com will cease to be hosting anything. Source: about 2 years ago

More likely that the art will live as long as the gateway provider lives. Even for the $65M Beeple purchase, the IPFS hash points to a gateway provided by makersplace.com, which is an NFT minting startup. If they go bust, no one maintains the IPFS gateway, and the $65M NFT points to an IPFS hash that returns a json file that contains a description, a few properties related to the NFT, and a dead link.

More than half of the artists $100K club sell on more than one platform, the average being two. SuperRare was the most popular amongst the sample group followed closely by MakersPlace. https://media.giphy.com/media/l0MYvOjkBiEB0zjTq/giphy.gif. Source: over 2 years ago
