Ethereum

are there any NFT services that let you watch for listings of certain traits in a collection and send you a push/email notification if something becomes available?

feels like something opensea might have 

or will have soon as they continue to build out their new platform

great way to abstract/handle multiple channels, I would just gather data I want w ponder, and have a system that sends whatever needed via novu to recipients

Maybe w indexsuppy live query‽ https://www.indexsupply.net/

doesn't need to be decentralized - i just want to set some criteria and receive an email when it becomes available to purchase. you can do this with indexing infra like ponder.sh today but would prefer not to have to build my own

All I keep hearing about is the death of nft api’s.
