Centralized LLM Routing Engine

One gateway for every LLM call — budget tracking, rate limiting, multi-provider fallbacks and circuit breaker patterns so product teams survive provider outages without noticing them.

Dynamic Tool Framework

Turns any REST API into an agent-callable tool: configure the request, fire a live test call to capture the real response shape, annotate the keys — and the LLM tool schema writes itself. Hand-written integrations: eliminated.
