Implementation Example

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

const url = "https://data.cityofnewyork.us/resource/h9gi-nx95.json?$limit=5";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "Authorization": "Bearer YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

import requests

url = "https://data.cityofnewyork.us/resource/h9gi-nx95.json?$limit=5"
headers = {"Authorization": "Bearer YOUR_API_KEY"}

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

curl "https://data.cityofnewyork.us/resource/h9gi-nx95.json?$limit=5"

What Can You Build?

// Fetch open data records
const headers = { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' };
const response = await fetch(`https://dev.socrata.com`, { headers });
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));
});

// Fetch data for visualization
const headers = { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' };
const response = await fetch(`https://dev.socrata.com`, { headers });
const data = await response.json();
const dataset = data.data || data.results || data;
console.log('Dataset loaded:', Array.isArray(dataset) ? dataset.length : 1, 'records');
document.getElementById('viz').innerHTML =
  `<pre>${JSON.stringify(dataset, null, 2)}</pre>`;

// Search and filter open data
const headers = { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' };
const response = await fetch(`https://dev.socrata.com`, { headers });
const data = await response.json();
const results = data.results || data.data || [];
const filtered = Array.isArray(results) 
  ? results.filter(r => r.name || r.title)
  : [results];
console.log(`Found ${filtered.length} matching records`);

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.

{
  "code": "dataset.missing",
  "error": true,
  "message": "Not found",
  "data": {
    "id": "h9gi-nx95.json"
  }
}

{
  "code": "query.compiler.malformed",
  "error": true,
  "message": "Could not parse SoQL query \"select * limit !!!invalid!!!\" at line 1 character 16: Expected an integer, but got `!'",
  "data": {
    "query": "select * limit !!!invalid!!!",
    "position": {}
  }
}

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.
