## Description

OpenAI API Tester is a lightweight REST client preconfigured for the OpenAI API.

Features:
- Prefilled chat completions request template
- Bearer token authentication (your key stays in your browser)
- Syntax-highlighted JSON responses
- Request history with search and restore
- Import and export cURL commands
- Works with any OpenAI endpoint: chat, embeddings, images, audio

Your API key never leaves your browser - requests go directly from the extension to <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/12e27e533e8926661fcf6b0ae844bf20f199e811558bba18b332645449708001/http%3A//api.openai.com" rel="nofollow">api.openai.com</a>.
