## Sitemap Analyzer API — Parse & Validate XML Sitemaps

Instantly fetch, parse, and validate XML sitemaps for any website. Whether you're auditing a single sitemap or crawling a sitemap index with dozens of nested sitemaps, this API handles it automatically — returning every URL, its metadata, and structural insights in a clean JSON response.

Built for SEO engineers, web crawlers, technical auditors, and developers who need reliable sitemap data without writing brittle parsers or maintaining headless browser infrastructure.

## What Does This API Do?

Submit any sitemap URL and receive a structured breakdown of:

- **All discovered URLs** — with loc, lastmod, changefreq, and priority fields
- **Sitemap type detection** — standard sitemap, sitemap index, news sitemap, image sitemap, video sitemap
- **Nested index resolution** — automatically fetches and parses all child sitemaps from a sitemap index
- **URL count and statistics** — total URLs, unique domains, URL depth distribution
- **Validation flags** — detects malformed XML, missing required fields, oversized sitemaps, encoding issues
- **Response metadata** — HTTP status, content-type, response time, sitemap size

---

## Key Features

### Automatic Index Resolution
If the URL points to a sitemap index file, the API automatically fetches and parses all nested sitemaps — returning a unified list of every URL across all child sitemaps. No need to traverse the index manually.

### Comprehensive URL Extraction
Every `<url>` entry in the sitemap is extracted with its full metadata: location (href), last modified date, change frequency, and priority score. Null fields are preserved so your downstream logic can distinguish "not set" from "set to empty".

### Sitemap Type Detection
The API identifies which sitemap format is in use: standard URL sitemaps, sitemap indexes, Google News sitemaps, image sitemaps, and video sitemaps. This helps downstream consumers apply the correct parsing logic.

### Validation & Error Reporting
Receive actionable validation results: Is the XML well-formed? Are required fields present? Does the sitemap exceed Google's 50,000 URL / 50MB limits? Are encoding issues detected? These checks help you maintain clean, crawlable sitemaps.

### Fast & Reliable Fetching
Uses optimized HTTP fetching with browser-like headers, redirect following, and configurable timeouts. Handles gzip-compressed sitemaps automatically.

## Use Cases

**SEO Auditing Tools** — Check if a site's sitemap is valid, up-to-date, and contains the correct URLs before running a full crawl.

**Content Monitoring** — Track when new URLs are added to a sitemap by polling it periodically and comparing results.

**Competitor Research** — Discover all public URLs on a competitor's website by parsing their sitemap.

**Web Crawlers & Scrapers** — Bootstrap a crawl by seeding your queue with every URL from a site's sitemap.

**Search Engine Simulation** — Mimic how Googlebot discovers pages by reading sitemaps before crawling.

**Technical SEO Consulting** — Validate client sitemaps as part of an on-boarding audit checklist.
