Summary
In this chapter, we examined various off-chain sources of data relevant to the Web3 economy, categorizing the analysis into three main areas. For prices, we explored multiple APIs from traditional sources to exchanges, as well as an oracle. With news, we learned how to extract real-time headlines from the best dedicated news indexer as of the time of writing – namely, CryptoPanic. For X (formerly Twitter), we utilized its API to gauge the sentiment around an NFT protocol. This list of resources is not exhaustive, and we have only scratched the surface of the uses we can give to all this data.
In the next chapter, we will delve into NFTs and their applications in the gaming, art, and name service industries.
