Combine chickpeas and vinegar in a small saucepan and bring to a simmer. Remove from heat. Let stand for 30 minutes.
Drain chickpeas, removing any loose skins.
Preheat an air fryer to 390 degrees F (198 degrees C). Spread chickpeas evenly in the basket. Cook until dried out, about 4 minutes.
Transfer chickpeas into a heat-proof bowl and drizzle with oil and sea salt. Toss to coat. Return chickpeas to the air fryer and cook, shaking basket every 2 to 3 minutes, until lightly browned, about 8 minutes. Serve immediately.
