OpenAI CLI

open sourceexplicit relation

OpenAI CLI (openai) is OpenAI's official Apache-2.0 command-line tool for the OpenAI REST API. Commands mirror API resources, so you can create Responses, generate and edit images, upload and download files, submit and wait for Batch jobs, and query admin endpoints such as organization usage from a shell or script. Output can be readable text, JSON, JSONL or YAML with GJSON transforms. It is not a coding agent; for that OpenAI points to Codex CLI.

The CLI is free and open source under the Apache License 2.0. It calls the OpenAI API with your own API key (OPENAI_API_KEY, plus OPENAI_ADMIN_KEY for admin endpoints), so every request is billed at standard OpenAI API rates; see the OpenAI API pricing page.
