NYIAX has today (April 20) announced a tie-up with startup Rebel AI which the pairing claims will help advertisers and publishers verify ad marketplace contracts, meaning media buyers can be more safely assured they will get what they paid for. Under the terms of the agreement, the Rebel AI Passport product will be integrated into the NYIAX marketplace, meaning media buyers that choose it as the court of record for futures contracts can be better assured the terms of the contract will be delivered upon.
