Extraction of data from website imprints

The netEstate Imprint Crawler is able to find the imprint or contact page of a website and extract addresses, contact data and company names.

The Crawler can be used as Web service or via manual batch processing by us and is especially suitable for address verification. It respects the robots.txt, the robots meta element and popular german wording against the processing of contact data.

Emphasis currently is on Germany, Austria and Switzerland. The quality for other countries varies but can be optimized on demand.

Please notice that in order to prevent abuse, we never supply e-mail-addresses – only hashes of e-mail-addresses that can be used for comparison with existing data.


Not available for private individuals.

0,015 EUR + VAT per API-call / per crawled websites. The price for additional API-calls/websites halves at 20,000, 100,000, 500,000 API-calls/websites.

You buy a quota of calls for the Web-API (One HTTP-call per website, minimum purchase 6000 calls) or send us a file with websites to crawl. We will then send the results back as CSV file (service fee 60,- EUR + VAT, no minimum purchase).
