Silvanexum

AI agents loop, retry and resend growing context, and the bill shows up weeks later. Silvanexum meters every LLM call across OpenAI, Anthropic and Gemini (streaming included), ties cost to the customer, agent and trace behind it, and blocks calls before they break a budget. Plug in by swapping one base URL, or use SDK-only mode so prompts and keys never leave your servers. Python and TypeScript SDKs, an MCP server and an NVIDIA NeMo Relay plugin.
