GoldSrc Rest In Pawn (gRIP)
Представляет REST API для AMX Mod X скриптеров. Позволяет совершать https/http запросы асинхронно

Совместимость
- Требуется AMX Mod X 1.8.3+
- Работает как на HLDS так и на ReHLDS
- Linux (возможно появится в будущем поддержка Windows)

Особенности:
- Написан с расчетом на высокую производительность и стабильность сервера
- Полностью асинхронен
- Имеет встроенную поддержку JSON
