how to detect multisig transactions

i have a transaction example like this, i want to understand if this is multi sig (that i need more than 1 public key to spend this transaction), should i check hex(script) values under the vin, our vout, or is there any other way that we can understand this in the blockbook?

(what i want to see is, when im checking the transaction, i want to know if i can spend it, or do i need another public key to spend it?)
