Set your air fryer to preheat at 400°F (200°C).
Dry the chicken breasts with paper towels and place them in a mixing bowl; coat evenly with olive oil.
Combine smoked paprika, cumin, onion powder, salt, and pepper in a small bowl and press the spice mix onto both sides of each chicken breast.
Arrange the chicken breasts in the air fryer basket and cook for 4 minutes.
Turn the chicken over and cook for another 4 minutes, or until the internal temperature reads 165°F and the juice runs clear.
Once done, take the chicken out of the air fryer and serve right away for the best flavor and juiciness.
