RMI Intelligent Webhook System
|
|
===============================
|
|
Databus-powered webhook receiver and dispatcher.
|
|
Handles inbound webhooks from Arkham, Helius, Moralis, and any service.
|
|
Auto-caches, indexes in RAG, and triggers premium scanner analysis.
|
|
|
|
Architecture:
|
|
Webhook → Validate → Cache(DataBus) → RAG Index → Premium Scanner → Alert Pipeline
