What the Website Intelligence API does

Point it at any URL and get back SEO metadata, technology stack fingerprinting (50+ signatures), social tags, security headers, and sitemaps. Responses are JSON, the API runs behind the RapidAPI gateway for auth and rate limiting, and there's a free tier for prototyping.

When to use it

SEO audits

competitor analysis

lead enrichment

The example request

GET https://website-intelligence-by-datanest.p.rapidapi.com/analyze?url=https://github.com

Example JSON response

{
  "url": "https://github.com",
  "title": "GitHub · Build and ship software",
  "description": "Join the world's most widely adopted developer platform.",
  "techStack": [
    "React",
    "Ruby on Rails",
    "Fastly"
  ],
  "social": {
    "twitter": "https://twitter.com/github"
  },
  "headers": {
    "server": "GitHub.com",
    "x-frame-options": "deny"
  },
  "sitemap": "https://github.com/sitemap.xml"
}

Common parameters

Every request also needs your RapidAPI auth headers.

Parameter	In	Required	Example
url	query	Yes	https://github.com
x-rapidapi-key	header	Yes	YOUR_RAPIDAPI_KEY
x-rapidapi-host	header	Yes	website-intelligence-by-datanest.p.rapidapi.com

Step by step

1. Subscribe and get your key

Open the Website Intelligence API on RapidAPI, subscribe to the free BASIC plan, and copy your X-RapidAPI-Key.

2. Call the endpoint

The example call for this API is shown above. The quick-start snippets below send exactly that request in cURL, Python and Node so you get a real response on the first try.

3. Try it without code first

The Website Intelligence page has a live "Try it" panel — change the input, run it, and inspect the real JSON before you integrate.

4. Integrate and cache

Call it from your backend and cache responses where it makes sense. Most responses change slowly, so even a daily cache keeps you well within the free tier.

Quick-start code

curl --request GET \
  --url 'https://website-intelligence-by-datanest.p.rapidapi.com/analyze?url=https%3A%2F%2Fgithub.com' \
  --header 'x-rapidapi-host: website-intelligence-by-datanest.p.rapidapi.com' \
  --header 'x-rapidapi-key: YOUR_RAPIDAPI_KEY'
