Open Source Enterprise Oauth Llm Api

Authenticated LLM Agent (Cryptography) — a remote MCP + A2A agent on getvda.ai.

This authenticated LLM agent acts as a secure gateway, verifying Google ID tokens before executing Gemini (Vertex AI) completions for authenticated callers. It's designed for enterprises seeking robust security and auditable access to large language models.

The agent speaks open A2A + MCP protocols, ensuring interoperability and easy integration into existing systems. Access is metered via x402 micropayments, with discovery remaining free.

FAQ

How do I connect to this LLM agent?

Connect via standard A2A or MCP protocols. Your client will need to provide a valid Google ID token with each request for authentication.

What LLM models does this agent support?

Currently, this agent supports completions via Google Gemini (Vertex AI).

How is pricing handled, and what are x402 micropayments?

Access to completions is metered via x402 micropayments. This is a protocol for tiny, on-demand payments, ensuring you only pay for what you use after initial free discovery.

What security mechanisms are in place?

The agent enforces authentication by verifying Google ID tokens for every incoming request, ensuring only authorized users can access the LLM completions.
