ParseAPI's Free plan for the domain WHOIS API costs $0.00 per 1,000 domains. We check each provider's docs for 9 fields: Registrant, Registrar, Created on, Updated on and 5 more. ParseAPI's docs list none of the 9.
We haven't run ParseAPI through [our domain WHOIS API benchmark](https://datacircle.dev/best-domain-whois-api.txt) yet.
This plan is free. We rank 543 plans for domain WHOIS APIs by price. Half the plans cost $1.639 or less per 1,000 domains. [See the best free domain WHOIS API plan.](https://datacircle.dev/best-domain-whois-api.txt)
[Searchwire's $10 pack](https://datacircle.dev/domain-whois-apis/searchwire/10-pack/llms.txt) is the cheapest paid plan per 1,000 domains.
