**APIs profiled:** 1

Burner is the original second-phone-number app from Ad Hoc Labs (founded 2012, Los Angeles), letting people create multiple temporary or permanent phone numbers on a single iOS or Android device for privacy, communication management, and boundary-setting. Burner supports voice calls, SMS and MMS over VoIP/PSTN, with spam blocking, voicemail transcription, auto-reply and multi-line management. For developers, Burner exposes an OAuth 2.0 REST API (api.burnerapp.com) for programmatic line management and messaging, a webhook system for real-time event notifications, and the open-source Burner App Starter Kit (BASK) for building Burner-integrated apps and bots such as Hostbot and Ghostbot.
