Similarweb Scraper API

The Piloterr Similarweb Scraper API lets you extract public data from Similarweb as clean, structured JSON — no proxies, headless browsers or HTML parsing to maintain. Endpoints available in production:

SimilarWeb Domain API — Retrieve website traffic and engagement metrics for any domain from SimilarWeb, including visits, bounce rate, top keywords, and traffic sources.
Similarweb Search API — Search the Similarweb database to retrieve websites, companies, mobile apps, search keywords, and technologies associated with a given domain or keyword.

Use it for lead generation, CRM enrichment, market mapping, investment research or job market analytics.

Endpoint	Path	Credits	What you get
SimilarWeb Domain API	`/v2/similarweb/domain`	1	Retrieve website traffic and engagement metrics for any domain from SimilarWeb, including visits, bounce rate, top keywords, and traffic sources.
Similarweb Search API	`/v2/similarweb/search`	1	Search the Similarweb database to retrieve websites, companies, mobile apps, search keywords, and technologies associated with a given domain or keyword.

How it works

Create a free Piloterr account and copy your API key from the dashboard.
Send a GET (or POST) request to https://api.piloterr.com/v2/... with the header x-api-key: YOUR_API_KEY.
Receive structured JSON — Piloterr handles rendering, proxies, retries and parsing.

export PILOTERR_API_KEY="your-api-key"
pip install requests        # Python
# TypeScript: Node.js 18+ (native fetch), run with `npx tsx file.ts`

Every endpoint accepts both GET (query string) and POST (JSON body with the same fields).

FAQ

Is it legal to scrape Similarweb?

Collecting publicly available data is generally allowed in many jurisdictions, but rules depend on your country, the data you collect and how you use it. Avoid personal data unless you have a lawful basis, respect the website's terms where they apply, and get legal advice for your specific use case. This is not legal advice.

Do I need proxies or a headless browser?

No. Piloterr handles rendering, proxy rotation and retries on its side. You only send an HTTPS request with your x-api-key header and receive JSON.

How much does a request cost?

Credits per call: /v2/similarweb/domain 1, /v2/similarweb/search 1. See the Piloterr website for plans.

What data does the Similarweb API return?

Each endpoint returns structured JSON: SimilarWeb Domain — title, category, site_name, engagments, engagments.year, engagments.month; Similarweb Search — apps, apps.appStore, apps.googlePlay, keywords, websites[], websites[].name.

Which languages are supported?

Any language that can make an HTTP request. This README shows Python and TypeScript; the examples/ folder contains cURL, PHP, C#, Go, Java, Ruby and Node.js.
