Burner

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.

Burner publishes 1 API on the APIs.io network. Tagged areas include Company, Phone Numbers, SMS, MMS, and Voice.

The Burner catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Burner’s developer surface includes documentation, engineering blog, pricing, support, authentication, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/burner: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
