How to Find and Extract All URLs from a Website Using Olostep Maps API and Streamlit

Introduction

When building web crawlers, competitive analysis, SEO audits, or AI agents, one of the first critical tasks is finding all the URLs on a website.

While traditional methods like Google search tricks, sitemap exploration, and SEO tools work, there's a faster, modern way: using Olostep Maps API.

In this guide, we'll:

Introduce the challenge of URL discovery
Show how to build a live Streamlit app to scrape all URLs
Compare it with traditional techniques (like sitemap.xml and robots.txt)
Provide complete runnable Python code

Target Audience: Developers, Growth Engineers, Data Scientists, SEO specialists, and Founders who need structured, scalable scraping.

Why Extract All URLs?

Finding every page on a website can help you:

Analyze site structure (for SEO)
Scrape website content efficiently
Find hidden gems like orphan pages
Monitor website changes
Prepare data for AI agents and automation

Traditional Methods (Before Olostep)

1. Sitemaps (XML Files)

Webmasters often create XML sitemaps to help Google index their sites. Here's an example:


  
    https://example.com
  
  
    https://example.com/about

To find sitemaps:

Visit /sitemap.xml (e.g., https://example.com/sitemap.xml)
Check /robots.txt (it usually links to the sitemap)

Other possible sitemap locations:

/sitemap.xml.gz
/sitemap_index.xml
/sitemap.php

You can also Google:

site:example.com filetype:xml

Problems:

Some websites don't maintain updated sitemaps.
Not all pages may be listed.
Dynamic websites (heavy JavaScript) often leave out many pages.

2. Robots.txt

Example:

User-agent: *
Sitemap: https://example.com/sitemap.xml
Disallow: /admin

Good for finding disallowed URLs and sitemap links, but again not comprehensive.

The Modern Solution: Olostep Maps API

✅ Find up to 100,000 URLs in seconds.

✅ No need to manually find sitemap or robots.txt.

✅ Simple API call.

✅ No server maintenance or IP bans.
