Sitemap API for Price Monitoring

Before you start

• A SitemapKit API key stored in a server-side environment variable.
• A target domain or sitemap URL and a clear success criterion for the price monitoring workflow.

Implementation workflow

1. 1

   Define the workflow objective

   Start from this concrete goal: Enumerate all product URLs for price tracking

2. 2

   Request the sitemap data

   Use the implementation example below from server-side code and pass the target domain or sitemap URL required by the workflow.

3. 3

   Validate and reuse the result

   Check the returned sitemap URLs and page records against the expected outcome for price monitoring before sending the data to the next system.

Why use SitemapKit?

• Find all product URLs on any e-commerce site
• Track new products via sitemap changes
• Use lastmod to detect recently updated prices
• Scale across hundreds of competitor sites

Implementation example

import requests

resp = requests.post(
    "https://sitemapkit.com/api/v1/sitemap/full",
    headers={"x-api-key": "YOUR_API_KEY"},
    json={"url": "competitor-store.com"}
)

# Filter for product pages
products = [
    u for u in resp.json()["urls"]
    if "/products/" in u["loc"] or "/p/" in u["loc"]
]

# Check recently updated (price changes?)
recent = [p for p in products if p.get("lastmod", "") > "2025-03-01"]
print(f"{len(recent)} products updated recently")
