How to Use the HumanizerPro API: Step-by-Step

Step 1: Get Your API Key

Sign up at Humanizer PRO API and get your developer API key. This key lets you authenticate your requests.

Step 2: Humanize AI Text

Make a POST request to /api/v1/humanize with your AI-generated text.

Example: JavaScript fetch

const apiKey = "YOUR_API_KEY"; const aiText = "This AI generated content is robotic and unnatural.";  fetch("https://api.humanizerpro.ai/api/v1/humanize", {   method: "POST",   headers: {     "Content-Type": "application/json",     "Authorization": Bearer ${apiKey}   },   body: JSON.stringify({     text: aiText,     modelType: "standard"   }) }) .then(res => res.json()) .then(data => {   console.log("Humanized text:", data.humanized_text);   console.log("Confidence score:", data.confidence_score); }) .catch(err => console.error("API error:", err)); 

Step 3: Use Other API Endpoints

The same API key works for:

• /api/v1/detect-ai — Detect AI-generated text
• /api/v1/plagiarism-checker — Check content originality
• /api/v1/fact-checker — Verify facts

Each endpoint uses similar JSON input and output formats.
