As the digital landscape continues to evolve, the need for reliable and efficient domain name lookup APIs has never been more critical. Developers and businesses alike require tools that not only provide accurate domain information but also enhance their cybersecurity measures, streamline domain management, and facilitate research. In this blog post, we will explore the best alternatives to the Domain Name Lookup API, detailing their features, capabilities, pricing, pros and cons, ideal use cases, and how they differ from the Domain Name Lookup API.

1. Domain Lookup API

The Domain Lookup API is a powerful tool that provides developers with two primary functionalities: checking domain availability and performing WHOIS domain lookups. This API is designed to assist users in making informed decisions regarding domain registration and management.

Key Features and Capabilities

The Domain Lookup API offers two main features:

• Check Domain Availability: This feature allows users to validate a domain's availability and retrieve various domain-related data by providing the domain URL. For example, if a user inputs applesupport.app, the API will return whether the domain is available for registration.

{"status":"OK","request_id":"279d959e-5eca-46aa-bb29-d6fc1b507a35","parameters":{"domain":"applesupport.app","currency":"USD"},"data":{"domain":"applesupport.app","sld":"applesupport","tld":"app","valid":true,"available":true,"register_price":"0","purchase_price":"0","transfer_price":"14","renew_price":"14","currency":"USD","is_premium":false,"is_aftermarket":false,"tld_requirement":"HSTS_PRELOAD","whois_privacy_offered":true,"domain_positives":["Recent worldwide popular tld","Correct spelling","Okay transcribability"]}}

• Check WHOIS Domain: This feature enables users to perform a WHOIS domain lookup by providing the domain URL. It returns detailed information about the domain, including registration details and ownership.

{"status":"OK","request_id":"f1a068f9-d73a-4c81-9725-47f6655ccca1","parameters":{"domain":"netflix.com"},"data":{"domain":"netflix.com","sld":"netflix","tld":"com","whois":"Domain Name: netflix.com\nRegistry Domain ID: 1404215_DOMAIN_COM-VRSN\nRegistrar WHOIS Server: whois.markmonitor.com\nRegistrar URL: http://www.markmonitor.com\nUpdated Date: 2021-10-09T09:37:28+0000\nCreation Date: 1997-11-11T05:00:00+0000\nRegistrar Registration Expiration Date: 2023-11-10T00:00:00+0000\nRegistrar: MarkMonitor, Inc.\nRegistrar IANA ID: 292\nRegistrar Abuse Contact Email: [email protected]\nRegistrar Abuse Contact Phone: +1.2086851750\nDomain Status: clientUpdateProhibited (https://www.icann.org/epp#clientUpdateProhibited)\nDomain Status: clientTransferProhibited (https://www.icann.org/epp#clientTransferProhibited)\nDomain Status: clientDeleteProhibited (https://www.icann.org/epp#clientDeleteProhibited)\nDomain Status: serverUpdateProhibited (https://www.icann.org/epp#serverUpdateProhibited)"}}
