How to Embed & Use the Data

Fetch & Display with JavaScript

The simplest way to embed current poll numbers in your own website or app. The JSON endpoint is served with CORS headers so you can call it directly from the browser.

fetch('https://britpolls.co.uk/data/current-vi.json')
  .then(r => r.json())
  .then(data => {
    // data.reform_uk => 28, data.labour => 18, etc.
    document.getElementById('reform-pct').textContent
      = data.reform_uk + '%';
    document.getElementById('updated').textContent
      = data.updated;
  });

Embed in PHP

For server-side rendering, use file_get_contents and json_decode. We recommend caching the result locally to avoid external HTTP calls on every page load.

<?php
$vi = json_decode(
  file_get_contents(
    'https://britpolls.co.uk/data/current-vi.json'
  ), true
);
echo 'Reform UK: ' . $vi['reform_uk'] . '%';
echo 'Updated: '   . $vi['updated'];
?>

Python / curl

# Python
import requests
data = requests.get('https://britpolls.co.uk/data/voting-intention.json').json()
polls = data['polls']
print(f"Latest poll: {polls[0]['pollster']} - Reform {polls[0]['reform_uk']}%")

# curl
curl https://britpolls.co.uk/data/current-vi.json | python3 -m json.tool
