Authentication

Secure your API requests

All API requests must be authenticated using an API key. Include your key in the Authorization header of every request.

Header Format

Authorization: Bearer YOUR_API_KEY

Code Examples

Quick start with common languages

JavaScript (Node.js)

// Create a new token using fetch
const response = await fetch('https://api.erc20maker.app/v1/tokens/create', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    name: 'My Token',
    symbol: 'MTK',
    decimals: 18,
    totalSupply: '1000000',
    template: 'standard'
  })
});

const token = await response.json();

Python

import requests

response = requests.post(
    'https://api.erc20maker.app/v1/tokens/create',
    headers={
        'Authorization': f'Bearer {API_KEY}',
        'Content-Type': 'application/json'
    },
    json={
        'name': 'My Token',
        'symbol': 'MTK',
        'decimals': 18,
        'totalSupply': '1000000',
        'template': 'standard'
    }
)

token = response.json()

cURL

curl -X POST https://api.erc20maker.app/v1/tokens/create \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"My Token","symbol":"MTK","decimals":18,"totalSupply":"1000000","template":"standard"}'
