DomainRef's domain WHOIS API on its Pay per call plan. It costs $5.00 per 1,000 domains. DomainRef's docs list 7 of the 9 fields on our checklist: Registrar, Created on, Updated on, Expires on, Name servers, Statuses, DNSSEC.
We haven't run DomainRef through [our domain WHOIS API benchmark](https://datacircle.dev/best-domain-whois-api.txt) yet.
Half of the 316 plans we rank by price cost $1.495 per 1,000 domains or less. This plan costs less per 1,000 domains than 11% of the 316 plans.
[Searchwire's $10 pack](https://datacircle.dev/domain-whois-apis/searchwire/10-pack/llms.txt) is the cheapest paid plan per 1,000 domains. Searchwire's domain WHOIS API costs nothing beyond the plan price.
