TimHeuer.OpenAIPluginMiddleware 1.0.27

OpenAI Plugin manifest middleware for ASP.NET Core

This is a middleware for ASP.NET Core that will add a manifest file to the response for OpenAI Plugins in the default location of /.well-known/ai-plugin.json.

For more information on OpenAI Plugins see the OpenAI Plugin documentation.

Installation

This is a NuGet package so if you are using Visual Studio just use the Package Manager and search for 'TimHeuer.OpenAIPluginMiddleware' (enable checking for pre-release) and install.

Additionally you can install the package using the .NET CLI if you are using other tools:

$ dotnet add package TimHeuer.OpenAIPluginMiddleware --version 1.0.10-pre

Usage (pattern using ASP.NET minimal hosting/APIs)

Add the middleware to your Program.cs file (below is just an example, substitute your options):

builder.Services.AddAiPluginGen(options =>
{
    options.NameForHuman = "Weather Forecast";
    options.NameForModel = "weatherforecast";
    options.LegalInfoUrl = "https://example.com/legal";
    options.ContactEmail = "noreply@example.com";
    options.LogoUrl = "https://example.com/logo.png";
    options.DescriptionForHuman = "Search for weather forecasts";
    options.DescriptionForModel = "Plugin for searching the weather forecast. Use It whenever a users asks about weather or forecasts";
    options.ApiDefinition = new Api() { RelativeUrl = "/swagger/v1/swagger.yaml" };
});

And then after the builder is built, add the middleware:

app.UseAiPluginGen();

Options

The options are mostly required to conform the plugin schema specification. Some defaults are provided:

• Api/Type: "openapi"
• Api/IsUserAuthetnication: "false"
• Api/RelativeUrl: "/openapi.yaml"
• SchemaVersion: "v1"
• Auth/Type: "none"
