I think about "inputs": "script_asm", "required_signatures", "type"; "outputs": "required_signatures", "type". What do you think ?

Looks good as long as it supports SegWit, otherwise it won't recognize them.
Based the description: github.com/blockchain-etl/bitcoin-etl-airflow - transactions.json#L125-L127

Code:

{
"name": "type",
"type": "STRING",
"description": "The address type of the spent output"
},

Alternatively, for bitcoin-cli / console: look for OP_CHECKMULTISIG or OP_CHECKMULTISIGVERIFY at the end of the script.
That's 0xAE or 0xAF at the end of either asm or hex.
If it is SegWit, it should have "txinwitness" and it's at the end of it.
