# TidyTools, free: Domain WHOIS API

> Registration dates, registrar, availability and DNS records for many domains at once.

TidyTools's BASIC plan for the domain WHOIS API costs $0.00 per 1,000 domains. We check each provider's docs for 9 fields. TidyTools's docs list 8: Registrant, Registrar, Created on, Updated on, Expires on, Name servers, Statuses, DNSSEC.
We haven't run TidyTools through [our domain WHOIS API benchmark](https://datacircle.dev/best-domain-whois-api.txt) yet.
This plan is free. We rank 495 plans for domain WHOIS APIs by price. Half the plans cost $1.575 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. Searchwire's domain WHOIS API costs nothing beyond the plan price. [C99.nl's $25 yearly plan](https://datacircle.dev/domain-whois-apis/c99-nl/25-yearly/llms.txt) costs the least for 10,000 domains a month: $2.08.
