Any portal to see OP_RETURN messages in readable format?

[100bitcoin]

All of you might already know that Block #210000, #420000, #630000 & #840000 are special block. These are the 4 blocks where halving was done. Many paid extra fee to get their transaction included in these blocks. Lots of people sent messages through OP_RETURN to be a permanent part of Bitcoin history. I am looking for a way to surf those messages in a readable format. Do any of you aware of any portal to see OP_RETURN messages in readable format?

Block #210000: https://mempool.space/block/000000000000048b95347e83192f69cf0366076336c639f9b7228e9ba171342e

Do you mean in its Hexagonal format?
You can use this site to change it to text https://www.rapidtables.com/convert/number/hex-to-ascii.html And the other way around if you planing on making an OP return transaction.

These blocks were mined before Inscriptions and you will not find any useful data in them, extract the OP_RETURN data from hexadecimal to ASIC or UTF8.
There was a project for a site that helped you for full text search engine for Bitcoin, but it no longer works https://bitcointalk.org/index.php?topic=5450316.msg62154972#msg62154972

https://opreturn.net/

You can even use that site to put into OP_RETURN  your own message to save it forever in blockchain, truth to be said, relevant to dogecoin, but this fun will cost you nothing contrary to bitcoin.

However,  the engine of  this site is not able to decode messages encoded in the rules of the runes protocol. Such kind of messages  have spammed the net after halving.

It is able  to perform HEX=> extended -ASCII  decoding, solely.

Indeed they are halving related blocks. But this posting of garbage on the blockchain "to be part of history" is - no offense - an overrated commercial crap. If one wants to add a message to the blockchain he doesn't have to make those fat P2TR ordinals anyway and clearly not pay bitcoins for it, while the people wanting to use bitcoin as... bitcoin... are angrily looking at the mempool "sending best wishes" to the ones spamming it.

And my question is: do you have a personal benefit off this?
I'm asking since it's the second topic I read which you've made on theses "special" block's inscriptions and I start to think that you are trying to artificially create some hype around the ordinals from that block.
