Dry chickpeas very well with paper towels. In a medium bowl, toss chickpeas, oil, chili powder, and salt.
Transfer chickpea mixture to an air-fryer basket, scraping bowl to get all of the oil. Cook at 370° until crispy and golden brown, 10 to 14 minutes.
Serve chickpeas warm or at room temperature. Grate lime zest over top.
