The website is now dead.
It was probably dismissed due to high operational costs.
Would you happen to know of any other alternatives to search for OP_Codes?
Are you planning to release some code to be used?
I landed here because of this thread:
Searching for OP_return data What kind of search capabilities are you looking for?
I could probably add them to burned.money - it already indexes all OP_RETURNs, but the search doesn't extend to cover them. It is possible to view tx lists if you already know the value you want, though.
For example, you can search for "OP_RETURN Ballet" to find all blocks manufactured into Ballet Bitcoin Blocks by going to
https://burned.money/script/6a4c0642616c6c6574.
If you just need an ASCII partial match across OP_RETURN outputs, that should be pretty easy to add.
Fancier stuff like image/etching searches would probably merit its own service, which again may not be too hard to bring up.
