Resolves the same way as the corresponding Metaculus question. Its description is copied below:

OpenAI has been working on developing and improving language models for many years. They have released several versions of their GPT (Generative Pre-training) language model, starting with GPT in 2018 and followed by GPT-2 in 2019 and GPT-3 in 2020. These models have been designed to generate human-like text and have been used in a variety of applications, such as language translation, text summarization, and conversation generation.

ChatGPT launched in December 2022 with an open web interface that requires signing in. They claim to have reached more than 1 million users within the first 5 days.

As of Dec 23, 2022, OpenAI has only the web interface for ChatGPT, requiring the user to sign in and with other basic limitations. There is no API for making programmatic calls to ChatGPT. There is a paid API for GPT-3.

Will OpenAI release a public API for programmatically querying ChatGPT before April 1, 2023?

This resolves as Yes if, before April 1, 2023, an API for ChatGPT (with that name) is publicly available according to credible sources. For the purposes of this question the API will be considered publicly available if a paid or free version is available to the general public.
