Where can I find the Taproot script?

If you’re looking for a blockchain explorer for Taproot scripts, there’s scriptpath.info (disclaimer: I created it). It takes the Taproot script path input, decodes that script, and displays only the transactions providing some additional information. However, retrieving transactions in any way is not permitted.

For any meaningful analysis you will probably need to read the blockchain from your local node and extract the Taproot script yourself (how to do this can be found in other answers on this site or read BIP341).
