FeatBit Flag Evaluation & Insights API

Direct HTTP access to FeatBit's evaluation server — the foundation for building custom SDKs on any platform (Kotlin, Swift, Android, iOS, Unity, embedded, etc.).

Official documentation:

• Flag Evaluation API: https://docs.featbit.co/api-docs/flag-evaluation-api (source: https://github.com/featbit/featbit-docs/blob/main/pages/api-docs/flag-evaluation-api.md)
• Track Insights API: https://docs.featbit.co/api-docs/track-insights-api (source: https://github.com/featbit/featbit-docs/blob/main/pages/api-docs/track-insights-api.md)

When to Use This Skill

Activate when users:

• Build custom FeatBit SDK for Android, iOS/Swift, Kotlin, Unity, or any platform without an official SDK
• Call the evaluation server directly via HTTP without using a client library
• Need to implement flag evaluation + A/B experiment tracking from scratch
• Ask about sendToExperiment, variation insights, custom metric events, or batch insight payloads
