https://docs.opensea.io/reference#api-overview

No this issue is about fetching data from the OpenSea API, but you don’t need it to display NFTs listed on OpenSea.

For example in this case, the interactive web page is defined using the non-standard animation_url field, but you can access it using rawData: https://codesandbox.io/s/nft-rawdata-n41qe?file=/src/App.js

+1 for this. Would probably be a more reliable (albeit, more centralized) nft fetcher. There are several mainstream NFT projects that the ethereum fetcher was unable to load due to api inconsistencies.
