JavaScript / Node.js

const response = await fetch('https://api.injectapi.com/api/extract', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-API-Key': 'YOUR_API_KEY'

  body: JSON.stringify({
    url: 'https://www.amazon.com/dp/B08N5WRWNW',
    mode: 'product',
    extract: true
  })
});

const data = await response.json();
console.log(data.data);

Python

import requests

response = requests.post(
    'https://api.injectapi.com/api/extract',
    headers={
        'Content-Type': 'application/json',
        'X-API-Key': 'YOUR_API_KEY'
    },
    json={
        'url': 'https://www.amazon.com/dp/B08N5WRWNW',
        'mode': 'product',

3. Extraction Modes

InjectAPI supports 6 different extraction modes, each optimized for specific use cases:

general - Extract any structured data
product - E-commerce product pages
article - Blog posts and news articles
profile - Social media profiles
contact - Contact information pages
search - Search results pages

Raw HTML Mode

If you want to parse HTML yourself, you can disable AI extraction by setting extract: false:

const response = await fetch('https://api.injectapi.com/api/extract', {
  method: 'POST',
  headers: {
    'X-API-Key': 'YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    url: 'https://example.com',
    extract: false // Raw HTML only (faster, 1-2 seconds)
  })
});

// Response includes raw HTML
const data = await response.json();
console.log(data.data.html);

How It Works: 3-Tier Extraction System

InjectAPI uses an intelligent 3-tier extraction system that automatically selects the best method for each retailer:

Tier 1: Structured Data Extraction - Extracts JSON-LD, Microdata, and Open Graph tags embedded in HTML. 100% accuracy, 10x faster than AI. Works with eBay, Target, Amazon (80%+ of listings).
Tier 2: Custom DOM Extraction - Hand-crafted CSS selectors optimized per retailer. 100x faster than AI, 100% accuracy when selectors are current. Used for Target, eBay, Walmart.
Tier 3: AI Extraction - Uses Groq LLaMA 3.1 8B for intelligent extraction when structured data and custom selectors fail. 95% accuracy, 0.5-2 seconds generation time.
Tier 4: Validation Layer - Validates all extracted data to prevent hallucinations, wrong URLs, fake prices, and duplicates.

API Keys

InjectAPI uses API keys to authenticate requests. You can view and manage your API keys in your dashboard.

Using Your API Key

Include your API key in the X-API-Key header with every request:

curl -X POST https://api.injectapi.com/api/extract \
  -H "X-API-Key: ik_1234567890abcdef" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

JavaScript Example

fetch('https://api.injectapi.com/api/extract', {
  method: 'POST',
  headers: {
    'X-API-Key': 'ik_1234567890abcdef',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    url: 'https://example.com'
  })
})

API Key Format

API keys start with the prefix ik_ followed by a random string:

ik_1234567890abcdef

Security Best Practices

Never expose your API key in client-side code or public repositories
Use environment variables to store your API key
Regenerate your key if you suspect it has been compromised
Use different keys for development and production

Monitoring Usage

Track your API usage in real-time from your usage dashboard. Set up alerts to be notified when approaching your monthly limit.
