Example API Usage

With just a few lines of code, you can fetch Markdown from any webpage or PDF:

cURL

URL="https://www.example.com"
curl -X GET https://platform.lemino.ai/api/url2md/$URL \
  -H "x-api-key: YOUR_API_KEY" \
  -H "accept: text/plain"

JavaScript (Fetch)

const url = 'https://www.example.com';
const apiUrl = 'https://platform.lemino.ai/api/url2md/' + url;

const response = await fetch(apiUrl, {
  method: 'GET',
  headers: {
    'x-api-key': 'YOUR_API_KEY',
    'accept': 'text/plain'
  }
});

const markdown = await response.text();
console.log(markdown);

Python (requests)

import requests

url = 'https://www.example.com'
api_url = 'https://platform.lemino.ai/api/url2md/' + url
headers = {
  'x-api-key': 'YOUR_API_KEY',
  'accept': 'text/plain'
}

response = requests.get(api_url, headers=headers)
markdown = response.text
print(markdown)

PHP (cURL)

<?php

$url = 'https://www.example.com';
$api_url = 'https://platform.lemino.ai/api/url2md/' . $url;

$headers = [
    'x-api-key: YOUR_API_KEY',
    'accept: text/plain'
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

echo $response;

?>

Chunked Output

Note that if you use json output, large content will automatically be chunked into pieces intelligently. For json output instead of plain text, just use the following header.

'accept': 'application/json'

Why This Matters

If you’re building AI applications—whether it’s a RAG system, chatbot, document pipeline, or knowledge base - having clean, structured, noise-free data is crucial. Lemino's URL to Markdown API ensures your AI consumes only what matters, the real content.
