NetAPI vs Domains Index: daily domain datasets vs one-off domain databases

Q: Does NetAPI cover the same domains as Domains Index?

NetAPI tracks {zones_total} zones and {domains_total} domains, updated daily from registry zone files and registry data; Domains Index states about 255 million domains.

A factual comparison of NetAPI and Domains Index (domains-index.com).

Domains Index and NetAPI both sell lists of registered domain names, but the products are built differently: Domains Index sells domain databases as one-off downloads (all gTLDs, all ccTLDs, regional bundles) with paid update subscriptions on top, while NetAPI is a daily updated data service with enriched per-domain datasets, registrar and DNS-provider data, lookup tools and an API. This page compares both feature by feature.

Why choose NetAPI over Domains Index

NetAPI covers 1,584 domain zones and 460,900,044 domains, refreshed every day with new-domain deltas, and every dataset row carries DNS servers, IP address, hostname, IP country, email addresses, phone numbers, Majestic rank, registrar and registration/expiration dates – Domains Index lists are plain domain names, with WHOIS sold as a separate database. NetAPI adds registrar-grouped WHOIS datasets, DNS-provider lists, domain and reverse IP lookup and a documented API for automated downloads, none of which Domains Index offers. The free tier – the Top 1M website ranking, the compromised domains and compromised IPs feeds and the abuse research reports – is published under CC BY 4.0, whereas Domains Index offers sample downloads without a stated license. NetAPI is operated by a registered company with a published address, Terms of Service and Privacy Policy, and was built by the author of zonefiles.io, the now-closed service that started the domain-list category.

Frequently asked questions

Is NetAPI a replacement for Domains Index?

Yes. Everything Domains Index sells – complete lists of registered domains for gTLDs and ccTLDs, global and regional coverage, newly registered domains – is available on NetAPI as daily updated files and through an API, plus enriched datasets, registrar and DNS-provider data, lookup tools and free datasets that Domains Index does not offer.

What is the main difference between the two services?

The business model. Domains Index sells domain databases as one-off downloads and charges separately for update subscriptions; NetAPI is a subscription data service in which every list and dataset is refreshed every day and the "new domains" filter returns only what changed in the last 24 hours.

Which service gives more data per domain?

NetAPI. Domains Index lists contain domain names only, and WHOIS is sold as a separate database. Every NetAPI dataset row carries DNS servers, IP, hostname, IP country, email addresses, phone numbers, Majestic rank, registrar and registration/expiration dates.

Does NetAPI cover the same domains as Domains Index?

NetAPI tracks 1,584 zones and 460,900,044 domains, updated daily from registry zone files and registry data; Domains Index states about 255 million domains.

Can I automate downloads with NetAPI?

Yes. After sign-up you receive an API token and can fetch any list, dataset, DNS or registrar file and the compromised feeds with a single request, as described in the API documentation. Domains Index does not offer an API.

Can I try NetAPI without paying?

Yes. The Top 1M ranking, the compromised domains and compromised IPs feeds and the abuse research reports are free, need no registration and are licensed CC BY 4.0; sample files for the paid lists and datasets are available on every zone page.

NetAPI is operated by CodeRockers LTD, a company registered in Cyprus with a published postal address, Terms of Service and Privacy Policy, and was built by the author of zonefiles.io. Domains Index does not publish a legal entity or address on its website.
