API Documentation

Method 1: Bearer Token (Recommended)

Include your API key in the Authorization header:

curl "https://tariffsapi.com/api/v1/tariffs/resolve?hts=8541.10.00.80&origin=CN" \
  -H "Authorization: Bearer YOUR_API_KEY"

Method 2: X-API-Key Header

Alternatively, use the X-API-Key header:

curl "https://tariffsapi.com/api/v1/tariffs/resolve?hts=8541.10.00.80&origin=CN" \
  -H "X-API-Key: YOUR_API_KEY"

JavaScript (Node.js)

const axios = require('axios');

const API_KEY = 'YOUR_API_KEY';
const BASE_URL = 'https://tariffsapi.com/api/v1';

async function resolveTariff() {
  try {
    const response = await axios.get(`${BASE_URL}/tariffs/resolve`, {
      headers: {
        'Authorization': `Bearer ${API_KEY}`
      },
      params: {
        hts: '8541.10.00.80',
        origin: 'CN',
        resolve_chapter_99: true
      }
    });
    console.log(response.data);
  } catch (error) {
    console.error('Error:', error.response.data);
  }
}
