🚀 API Flow: The Lazy Person's API Workflow Automator

Tired of manual API testing?. API Flow lets you automate complex workflows using plain English.

Before API Flow (The Pain):

1. Open Postman.
2. Build POST /auth/login.
3. Run it, then frantically copy the auth token.
4. Build GET /user/profile.
5. Paste the token into the header.
6. Run it.
7. Repeat until you question your life choices.

With API Flow:

"Log in with username 'test' and password 'pass', then get my user profile"

That's it. 🎉

🏗️ How the Magic Happens

An AI-powered engine (using Google Gemini & LangGraph) acts as your brilliant, tireless intern. It takes your request, creates a multi-step plan, calls the APIs, and even cleverly passes data (like auth tokens) between steps. All you see is the result.

Tech Stack:

• Backend: FastAPI, LangGraph, Python
• Frontend: Next.js, React, TypeScript

🚀 Quick Start

Prerequisites:

• Python 3.11+
• Node.js 18+

cd api-flow

2. Backend Setup & Run

cd backend

# Install dependencies with uv (recommended) or pip

uv sync

# OR

pip install -r requirements.txt

# Create environment file

cp .env.example .env

# Add your GEMINI_API_KEY to .env

# Start the FastAPI server

uv run fastapi dev

# OR

python -m uvicorn app.main:app --reload --port 8000

3. Frontend Setup & Run

cd frontend
# Create environment file
