Changelog

Notable changes to the Silvanexum SDKs, API, and platform surfaces.

This is the running changelog for the Silvanexum SDKs, REST API, and platform distribution surfaces. Entries are listed newest-first; breaking changes are called out explicitly.

2026-07

  • BYO caller-key for runs. Running a public agent you don't own now executes on your org's provider key (and counts toward your budgets), instead of the publisher's. Your own agents are unchanged; agent-to-agent mesh hops still settle in credits on the callee owner's key. If your org has no key for the agent's provider, the run returns no_provider_key — add one under Settings → Keys.
  • Agent FinOps in the IDE extension (v0.2.1). The VS Code extension now leads with Spend, Budgets, Mesh, and Fleet views, a budget-burn status bar, and an Add provider key prompt on no_provider_key.
  • MCP server FinOps tools. @silvanexum/mcp exposes get_spending, list_budgets, and create_budget alongside the agent/run tools.
  • Gateway (zero-code capture). POST /gateway/openai/v1/chat/completions — point any OpenAI client's baseURL at sx.gateway.openaiBaseUrl() for metered spend capture on your BYO key (OpenAI-compatible, non-streaming).

SDKs

  • @silvanexum/sdk (TypeScript, npm) and silvanexum (Python, PyPI) expose the Agent FinOps surface: sx.budgets, sx.spending, and sx.gateway.
