Open Source Langchain Llm Orchestration Api

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

This LLM Orchestration Agent provides an open source LangChain LLM orchestration API, enabling seamless execution of prompts through a LangChain (system + human) chain using Gemini on Vertex AI. It offers optional LangSmith tracing for enhanced debugging and performance monitoring.

Designed for developers and enterprises seeking robust LLM integration, this agent speaks open A2A and MCP protocols, ensuring interoperability. It's metered via x402 micropayments, making discovery free and usage cost-effective.

FAQ

What LLM models does this agent support?

The agent specifically orchestrates prompts using Gemini models available on Google Cloud's Vertex AI platform.

How do I connect my application to this agent?

The agent exposes an API that communicates via open A2A and MCP protocols. Standard A2A/MCP client libraries can be used to connect and send prompts.

What is the pricing model for using this agent?

Usage of the agent is metered via x402 micropayments. Discovery of the agent is free, and you only pay for the actual processing of your prompts.

Can I use this agent with other LangChain components?

The agent itself is built with LangChain and orchestrates a specific type of chain (system + human prompt). It's designed to be a service that your application calls, rather than a library for direct composition with other LangChain components within your app.
