What Whoxy does

Whoxy (legal entity Whoxy.com) is a privately held, bootstrapped provider of WHOIS data APIs and bulk databases, founded in 2012 and headquartered in Sarasota, United States. The company operates a cloud-based service built on Amazon Web Services that retrieves live WHOIS records directly from upstream registries, traverses referral chains to authoritative servers, and converts the unstructured registrar responses into parsed JSON and XML fields via a proprietary parser. The platform supports 2,026 domain extensions across 1,596 TLDs and maintains a 700M+ domain database that underpins both real-time lookups and historical/reverse search products.

The commercial model is usage-based self-service with no monthly fee and no balance expiry. Standard WHOIS lookup queries start at $2 per 1,000 calls and scale down to $0.40 per 1,000 at the 25-million-query tier; WHOIS History and Reverse WHOIS APIs are priced at $5 and $10 per 1,000 queries respectively. One-time database licenses for the complete corpus (700M records) sell for $10,000, with country-specific subsets ranging from $100 to $6,250 and ancillary feeds (newly registered, dropped, expiring domains) at $495. The company targets developers, domain investors, security researchers, and enterprise portfolio managers exclusively through API signup and its website, with no sales motion.

Whoxy competes on price against DomainTools, Hexillion, WhoisXmlApi, and JsonWhois, publishing a "Lowest Price Guarantee" comparison table as its principal acquisition lever. The business shows no disclosed funding, headcount, or revenue; ownership commentary indicates an independently operated private company. Product breadth has expanded from a single WHOIS Lookup API to nine adjacent SKUs (history, reverse, bulk, complete and country databases, newly registered, dropped, expiring, and an archive), but the operating posture remains that of a small, profitable utility rather than a venture-scale platform.

Core offering

Whoxy provides a cloud-hosted WHOIS data API platform that returns parsed domain ownership information in JSON and XML formats via REST API calls. The core offering includes three APIs — WHOIS Lookup, WHOIS History, and Reverse WHOIS — supported by a proprietary parser that handles WHOIS registry referral chains across 2026 domain extensions, plus downloadable WHOIS databases covering 700+ million domain records.

Product overview

Whoxy is a unified WHOIS data platform providing multiple interconnected API and database services. The core offering consists of three main API products: WHOIS Lookup API (real-time domain ownership data), WHOIS History API (historical ownership records), and Reverse WHOIS API (domain ownership search by person/company). These APIs share a common data infrastructure with support for 1596 TLDs and 2026 domain extensions. Supplementary offerings include Bulk Whois Lookup for batch processing, domain databases (complete, newly registered, deleted, expiring), country-specific WHOIS databases, and a free API program. The complete WHOIS database contains 700+ million domain records. All services are built on cloud infrastructure and offer pay-as-you-go pricing starting at $2 per 1000 WHOIS queries.

Direct peers

• DomainTools: DomainTools is the most established incumbent in WHOIS and domain intelligence, offering WHOIS lookup, historical WHOIS, reverse WHOIS, and a broader portfolio including DNS, hosting, and IP intelligence. Whoxy explicitly benchmarks its pricing against DomainTools, and both serve the same developer, security, and enterprise customers with substantially overlapping APIs.
• DomainBigData: DomainBigData provides free and paid WHOIS lookup, reverse WHOIS, and historical WHOIS search across a large domain database. It competes with Whoxy in the same domain intelligence category, particularly for individual and SMB users performing registrant searches.
• ViewDNS.info: ViewDNS.info provides free and paid WHOIS lookup, reverse WHOIS, IP, and DNS tools. It overlaps with Whoxy's core WHOIS Lookup and Reverse WHOIS products and serves a similar SMB, researcher, and investigator customer base with comparable API and web-tool access patterns.
