Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

const url = "https://www.epa.gov/developers/data-data-products";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

import requests

url = "https://www.epa.gov/developers/data-data-products"
headers = {}

response = requests.get(url, headers=headers, timeout=30)
response.raise_for_status()
data = response.json()
print(data)

curl "https://data.epa.gov/efservice/PUB_DIM_FACILITY/ROWS/0:5/JSON"

What Can You Build?

// Fetch government/public data
const response = await fetch(`https://www.epa.gov/developers/data-data-products#apis`);
const data = await response.json();
const records = data.results || data.data || data.records || [];
const items = Array.isArray(records) ? records : [records];
items.slice(0, 5).forEach(item => {
  console.log('Record:', item.title || item.name || JSON.stringify(item));
});

// Visualize government data
const response = await fetch(`https://www.epa.gov/developers/data-data-products#apis`);
const data = await response.json();
console.log('Data source: EPA');
const stats = data.statistics || data.data || data;
document.getElementById('gov-dashboard').innerHTML =
  `<pre>${JSON.stringify(stats, null, 2)}</pre>`;

// Query government datasets
const response = await fetch(`https://www.epa.gov/developers/data-data-products#apis`);
const data = await response.json();
const results = data.results || data.items || [];
console.log(`Found ${results.length || 'N/A'} records`);
results.slice(0, 3).forEach(r => {
  console.log(`📋 ${r.title || r.name}: ${r.description || ''}`);
});
