## Description

Tired of switching between tabs and heavyweight tools just to test a simple API call? Meet <strong>zapi</strong> — a lightweight, privacy-friendly extension that lets you send and manage API requests directly from your browser, with zero setup or external dependencies.

Whether you're a developer debugging an endpoint, a QA engineer validating backend responses, or just someone experimenting with APIs, <strong>zapi</strong> gives you a fast, elegant way to interact with REST services — without ever leaving your current tab.

Why zapi?

Unlike bulky tools like Postman or Insomnia, zapi lives in your browser’s popup interface, so it’s available <em>instantly</em> — no windows, no distractions, no account needed. It's minimal, intuitive, and built for speed.

<strong>No installs. No login. No tracking. Just your APIs, your way.</strong>

What You Can Do with zapi:
<ul><li><strong>Compose and send API requests</strong> in seconds and GET, POST, PUT, DELETE supported out of the box</li><li><strong>Customize request headers and body</strong> with raw JSON, URL-encoded, or form data</li><li><strong>View responses instantly</strong> in a structured, formatted layout (status code, headers, body)</li><li><strong>Save and reuse your request history</strong> locally <em>(history feature coming soon)</em></li><li><strong>Toggle between light and dark themes</strong> for a comfortable experience, day or night</li><li><strong>One-click access on any tab</strong> and open zapi instantly from your browser toolbar</li></ul>
Privacy-First, Always

zapi runs <strong>entirely in your browser</strong>. It does <strong>not</strong> collect, transmit, or store any data externally. All your requests, responses, and preferences stay local and private, as they should.

This makes zapi ideal for sensitive environments, internal APIs, or anyone who values control over their workflow and data.

Who’s It For?
<ul><li><strong>Frontend &amp; Backend Developers</strong> – Test endpoints without context switching</li><li><strong>QA/Test Engineers</strong> – Quickly verify API behavior during debugging</li><li><strong>Students &amp; Learners</strong> – A simple way to explore REST APIs without complex setup</li><li><strong>Product Managers &amp; Tech Leads</strong> – Validate endpoints or check microservices health on the fly</li></ul>
Why Not Just Use Postman?

Postman is powerful, but often overkill for quick tasks. If you just want to test an endpoint or debug an API in under 10 seconds, zapi gets out of your way and lets you work faster, right from your browser.

Think of it as the <strong>"Spotlight Search"</strong> for API requests: quick, focused, and always within reach.

What’s Coming Next?
<ul><li>Local request history &amp; favorites</li><li>Export/import requests</li><li>Tab pinning &amp; persistent sessions</li><li>GraphQL &amp; WebSocket support</li><li>Keyboard shortcuts</li><li>And more — based on your feedback!</li></ul>
zapi is designed to make API testing simple, fast, and accessible to everyone — from power users to casual tinkerers. If you've ever wished you could test an endpoint without launching a heavy tool or losing your flow, give zapi a try.

<strong>→ Add it to your browser now and simplify your API workflow.</strong> <em>( You might never open Postman again! )</em>
