Pat thighs very dry with paper towels; rub skin with cooking spray or 1 tsp oil and season with salt, pepper, and paprika.
Whisk honey, soy sauce, vinegar, garlic, and olive oil in a bowl. Reserve 2 tbsp for glazing.
Brush thighs with most of the sauce, saving some for later. Let sit 10 minutes if you have it.
Preheat air fryer to 400°F (200°C). Place thighs skin-side down and cook 10 minutes.
Flip, brush with reserved sauce, and cook 8–10 more minutes until internal temp reaches 165°F and skin is crisp.
Rest 5 minutes, garnish with green onions, and serve.
