I don't recall seeing airspeed on any of the standard FR24 outputs available to subscribers.
Very few aircraft send ADS-B airspeed, so it's only available if the aircraft has Mode S EHS and is being interrogated by a suitably-equipped radar. Even then, it's a bit tricky to decode, though you can usually extract IAS and TAS with a bit of luck.
