API Getting Started Guide & Quickstart Tutorial

## ROLE
You are a developer experience (DX) writer who creates onboarding content for API platforms. You specialize in reducing time-to-first-call and designing tutorials that build developer confidence through progressive complexity.

## OBJECTIVE
Create a getting started guide that enables a developer to make their first successful API call within 10 minutes, understand core concepts, and feel confident to explore further.

## TASK
Write a complete getting started guide:

### Guide Structure

**1. Introduction (30 seconds to read)**
- What the API does and why it matters (2-3 sentences)
- What you will build in this guide (concrete outcome)
- Prerequisites list (account, tools, knowledge)
- Estimated completion time

**2. Account Setup (2 minutes)**
- Sign up process (step-by-step with screenshots placeholders)
- API key or credential generation
- Environment setup recommendations
- SDK installation commands for popular languages

**3. First API Call (3 minutes)**
- The simplest possible API call that returns meaningful data
- cURL example that works immediately after copy-paste
- Expected response with annotated output
- Troubleshooting common first-call errors

**4. Understanding the Response**
- Response structure walkthrough
- Key fields and what they mean
- How to extract the data you need
- Response metadata explanation

**5. Building Something Useful (5 minutes)**
- A realistic mini-project using 2-3 API calls
- Step-by-step code with explanations between blocks
- Running code example (not fragments)
- Expected output at each step
- Potential customization points highlighted

**6. Core Concepts**
- Resource model overview (how data is organized)
- Key terminology definitions
- Rate limiting awareness
- Error handling basics
- Authentication token management

**7. Next Steps**
- Links to common use case tutorials
- SDK documentation links
- API reference link
- Community and support resources
- Advanced features teaser

### Writing Principles for the Guide
- Every code block must be copy-paste runnable
- Use environment variables for credentials (never hardcode)
- Show the terminal output after each command
- Explain WHY before showing HOW
- Use progressive disclosure (simple first, then complexity)
- Include troubleshooting tips inline where errors commonly occur
- Test every code example before publishing (include testing notes)

### Multiple Language Versions
Provide the guide in at least three languages:
- cURL (universal)
- JavaScript/Node.js
- Python

Each version should feel native to that ecosystem, not a direct translation.

### Success Metrics
Define what success looks like:
- Time to first successful call < 10 minutes
- Developer can modify the example for their use case
- Developer knows where to find more information
- Zero ambiguity in any step
