OpenAI API Cookbook

OpenAI API Endpoints Explained

The OpenAI API is not just one endpoint, but instead a collection of different endpoints that can be used to generate text completions, images, and even transcribe audio. In this chapter, we dive into all these use cases covering the main endpoints that are used by developers when integrating the OpenAI API into their applications. By the end of this chapter, you will know how to use the diverse capabilities of the OpenAI API, the first step in building intelligent applications. You’ll understand the nuances of each endpoint, ensuring that you can tailor your integration to your specific needs. Whether you’re aiming to create dynamic text content, generate captivating visuals, or transcribe audio, you will learn how to accomplish these tasks all using the API.

Specifically, we will cover the following recipes in this chapter:

  • Generating customized responses using the Chat Completions endpoint
  • Creating pictures using the Images...

Technical requirements

This chapter requires you to have access to the OpenAI API (via a generated API key) and have an API client installed, such as Postman. You can refer to the Making OpenAI API requests with Postman recipe in Chapter 1 for more information on how to obtain your API key and set up Postman.

Generating customized responses using the Chat Completions endpoint

We previously explored the Chat Completions endpoint at the end of Chapter 1, but our request body was fairly simple and did not make use of the important parameters that we also discussed in the Running a completion request in the OpenAI Playground recipe. For example, we learned how the Chat Log could be used to fine-tune the responses that are generated. Additionally, the Chat Log feature can be used to deploy a chat bot inside your application.

In this recipe, we will cover how to generate responses using the Chat Completions endpoint while using the Chat Log parameters.

Getting ready

Ensure you have an OpenAI Platform account with available usage credits. If you don’t, please follow the Setting up your OpenAI Playground environment recipe in Chapter 1.

Furthermore, ensure you have Postman installed, you have created a new workspace, you have created a new HTTP request, and that the Headers for...

Creating pictures using the Images endpoint

The OpenAI API can do more than generate text (although that is its main purpose); it can also create images. It does this with a similar methodology to text generation, but instead of predicting characters, it predicts pixels. The inner workings of the model are complex (it involves the use of encoders, decoders, and embeddings), but that doesn’t stop us from actually using the model.

This significantly opens up the types of applications you can create with the OpenAI API. For example, you can create an application that produces stock images based on a user prompt. In this recipe, we will use the OpenAI API to generate several types of images.

How to do it…

  1. In Postman, create a new request by selecting the New button on the top-left menu bar, and then select HTTP.
  2. Change the HTTP request type from GET to POST in the Method drop-down menu (by default, it will be set to GET).
  3. Enter the following URL as the...

Generating transcripts using the Audio endpoint

In this recipe, we will learn how to use the OpenAI API’s Audio endpoint, which converts audio into text. This enables developers to create voice applications, such as voice agents and speech conversational bots.

Getting ready

This recipe will also use Postman, but the typical set of Headers that we use will need to be modified so that the HTTP client uses form data instead of typical JSON. In addition, we must have a sample audio file that we can use as an example to convert speech to text. Form data is a way to encode and send data as key-value pairs in HTTP requests instead of JSON-formatted strings. Form data is often used for uploading files.

After opening a new request in Postman, navigate to the Headers menu and delete the Content-Type application/json entry. This will force Postman to default to the Content-Type of the request based on what is passed in the request Body.

Next, we need an audio file. Any short...
