Semantic Kernel with Meridian

Drop-in OpenAI-compatible endpoint for Microsoft Semantic Kernel

Overview

Meridian exposes an OpenAI-compatible chat completions endpoint. You can point Semantic Kernel's AddOpenAIChatCompletion method at Meridian by overriding the endpoint URI and supplying your Meridian API key. No custom connector required.

Usage

using Microsoft.SemanticKernel;

var kernel = Kernel.CreateBuilder()
    .AddOpenAIChatCompletion(
        modelId: "gpt-4o",                  // or any model routed in Meridian
        apiKey: Environment.GetEnvironmentVariable("MERIDIAN_API_KEY"),
        endpoint: new Uri("https://api.meridian.fooglegiber.com/v1")
    )
    .Build();

var response = await kernel.InvokePromptAsync("Explain zero-knowledge proofs in two sentences.");
Console.WriteLine(response);

Parameters

Argument	Value
modelId	Model name as configured in your Meridian routes
apiKey	Your Meridian API key (keep in env vars)
endpoint	`https://api.meridian.fooglegiber.com/v1`

Notes

The /v1 suffix is required — Semantic Kernel appends /chat/completions automatically.
Streaming responses work out of the box; use InvokeStreamingAsync if desired.
All requests are encrypted in transit and authenticated via Meridian's API key header.
