Announcing Rare Sats support

Rare Sats have ballooned in popularity on places like Magic Eden and we're excited to announce our support for them in the SimpleHash API!

We have added a new chain ID called utxo where each "NFT" is an unspent transaction output. We are tracking all UTXOs on Bitcoin, but ones containing a rare sat have been added to a special collection with ID 0123456789abcdeffedcba9876543210.

You can find details about which rare sats (if any) the UTXO contains in the NFT response under extra_metadata > utxo_details, such as:
