Webilim.AI.Api is a minimal content-generation abstraction for multiple model providers. It exposes a single interface and provides ready-to-use services for Gemini, Ollama (local), and OpenRouter.

What this library does

• One interface for generating text content from different providers.
• Provider-specific implementations that you can swap via dependency injection.
• Lightweight DTOs and minimal dependencies.

Included providers

• Gemini: Webilim.AI.Api.Gemini.Service
• Ollama (local): Webilim.AI.Api.Ollama.Service
• OpenRouter: Webilim.AI.Api.OpenRouterAI.Service

NuGet packages

• Core: Webilim.AI.Api
• Gemini: Webilim.AI.Api.Gemini
• Ollama: Webilim.AI.Api.Ollama
• OpenRouter: Webilim.AI.Api.OpenRouterAI

Install

dotnet add package Webilim.AI.Api
dotnet add package Webilim.AI.Api.Gemini
dotnet add package Webilim.AI.Api.Ollama
dotnet add package Webilim.AI.Api.OpenRouterAI

Core interface

public interface IApiContentGenerator
{
    Task<ApiContentGeneratorResult> Generate(string prompt);
}

Register a provider and call Generate.

Gemini

builder.Services.AddSingleton<IApiContentGenerator>(sp =>
{
    var config = sp.GetRequiredService<IConfiguration>();
    return new Webilim.AI.Api.Gemini.Service(config["Gemini:ApiKey"]);
});

OpenRouter

builder.Services.AddSingleton<IApiContentGenerator>(sp =>
{
    var config = sp.GetRequiredService<IConfiguration>();
    return new Webilim.AI.Api.OpenRouterAI.Service(
        config["OpenRouter:ApiKey"],
        model: "meta-llama/llama-3.3-8b-instruct:free"
    );
});

Ollama (local)

builder.Services.AddSingleton<IApiContentGenerator>(sp =>
{
    // Example: http://localhost:11434
    return new Webilim.AI.Api.Ollama.Service("http://localhost", 11434);
});

Use the generator

var result = await generator.Generate("Hello!");
Console.WriteLine(result.Answer);

• API keys are injected externally (no secrets are stored in this repo).
• Gemini expects an API key string.
• OpenRouter expects an API key and optional model name.
• Ollama expects a base address and port to a local server.

Mock the interface without calling real APIs:

var mock = new Mock<IApiContentGenerator>();
mock.Setup(x => x.Generate(It.IsAny<string>()))
    .ReturnsAsync(new ApiContentGeneratorResult { Answer = "test" });
