OpenAI API Client

A client library for the D Programming Language that interfaces with the OpenAI REST API.

This client consists of files that have been generated automatically from OpenAI's OpenAPI Specification using the generation tool openapi-client.

Client Code Organization

• openai.model :: The package openai.model contains commonly used data types for the OpenAI API, which are generated from the #/components/schemas/ portion of the OpenAI OpenAPI Specification. This includes things like requests, responses, etc.
• openai.service :: The package openai.service contains logic to communicate with REST API endpoints. Generally, the module and class names are produced by concatenating the URL path fragments of the API endpoint, e.g. /chat/completions => chat_completions_service.d => class ChatCompletionsService.
• openai.server :: The default server URLs are stored here.
• openai.security :: Credentials needed to access the API, such as API tokens, usernames, and passwords are configured using this module.

Using the OpenAI Client

Below is an example of how to use the OpenAI Client:

import vibe.core.log : logDebug;
import vibe.data.json : Json, serializeToJson;
import openai.service.completions_service : CompletionsService;
import openai.model.CreateCompletionRequest : CreateCompletionRequest;
import openai.model.CreateCompletionResponse : CreateCompletionResponse;

import std.process : environment;

// 1. Use your OpenAI API Key as your security credentials.
// See https://platform.openai.com/account/api-keys
string apiKey = environment["OPENAI_API_KEY"];
Security.configureBearerAuth(apiKey);

// 2. Create a new service object corresponding to the URL path of the desired service.
auto service = new CompletionsService();

// 3. Invoke a specific action, e.g. creating a completion request.
service.createCompletion(
    // 4. Define any parameters needed for the request.
    CreateCompletionRequest.builder()
        .model("text-davinci-003")
        .prompt(Json("What is the cutest breed of rabbit? "))
        .echo(true)
        .maxTokens(2048)
        .build(),
    // 5. Indicate how different response codes should be handled.
    CompletionsService.CreateCompletionResponseHandler.builder()
        .handleResponse200((CreateCompletionResponse response) {
          logDebug("%s", serializeToJson(response).toString());
        })
        .build());

Development

Code Generation

The client code is generated from the file json/openapi.json. If this file is updated, then the client code can be regenerated using the following command:

dub build --config=generate

Testing

To run integration tests, an OpenAI API key is required. Once obtained, run integration tests with the following commands:

export OPENAI_API_KEY="sk-TS...N4G"
dub test --config=integration
