Open Source Langchain Llm Orchestration Api

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

This remote agent provides an open source LangChain LLM orchestration API, specifically designed for cryptographic applications. It executes prompts through a LangChain system and human chain using Gemini on Vertex AI, with optional LangSmith tracing for detailed insights.

Built for developers requiring secure and verifiable LLM interactions, this agent speaks open A2A and MCP protocols. It's metered via x402 micropayments, ensuring transparent, discovery-free usage for every call.

FAQ

How does this agent handle pricing and usage?

Usage is metered via x402 micropayments. This means you pay for each execution based on a pre-defined rate, ensuring transparent and discovery-free billing.

What LLM models are supported?

The agent currently orchestrates LangChain chains using Gemini models hosted on Vertex AI.

How do I connect to this agent?

The agent communicates using open A2A (Agent-to-Agent) and MCP (Microledger Consensus Protocol) protocols. You would connect via a client library compatible with these standards, typically over HTTP/S with appropriate authentication.

Can I integrate custom LangChain components?

The agent executes a pre-defined LangChain (system + human) chain. Customizing the *internal* chain structure would require deploying a modified agent. However, your prompts and inputs would flow through this existing structure.
