Looking to create a marketplace of sorts for my collection and have an opensea api key ready. However, the api only allows 4 calls a second. for a collection of 10,000, you’d be looking at 3-5 calls PER nft in some situations. How do tools like Rarity Tools get around this? I’m guessing they use a backend to request and cache the api calls from the end points but Rarity Tools serves up literally thousands of projects and millions of assets. Do they use multiple api keys?
Has anyone here set up a marketplace or website application that uses an OS API key? id be curious to know your thoughts
