Terms of Service

By accessing, browsing, or using the WhoisJSON website (whoisjson.com), API, or any related services (collectively, the "Service"), you acknowledge that you have read, understood, and agree to be bound by these Terms of Service ("Terms") and our Privacy Policy.

If you are entering into these Terms on behalf of a company, organization, or other legal entity, you represent and warrant that you have the authority to bind such entity to these Terms.

To access the WhoisJSON API, you must create an account. By registering, you agree to:

• Provide accurate, complete, and current information during registration.
• Maintain and promptly update your account information if it changes.
• Keep your API key and account credentials confidential and secure.
• Notify us immediately at support@whoisjson.com if you suspect unauthorized use of your account.
• Accept full responsibility for all activity that occurs under your account and API key.

You must be at least 18 years of age (or the age of legal majority in your jurisdiction) to create an account and use the Service.

You agree to use the WhoisJSON API only for lawful purposes and in compliance with these Terms. Acceptable use includes, but is not limited to:

• Integrating WHOIS, DNS, SSL, and availability data into your own applications, tools, or internal dashboards.
• Performing domain research, cybersecurity analysis, brand protection monitoring, or compliance auditing.
• Building automated workflows that query the API within the rate limits and quotas of your subscription plan.
• Displaying API data within your products, provided you attribute the source to WhoisJSON where feasible.

You are solely responsible for ensuring that your use of the API data complies with all applicable data-protection regulations (including GDPR, CCPA, and equivalent frameworks) and ICANN policies regarding the use of WHOIS data.

Your use of the API is subject to the request quotas and rate limits associated with your subscription plan. Details of each plan are available on our Pricing page.

• Free (Basic) plan: 1,000 requests per month, 20 requests per minute, across all endpoints.
• Paid plans: higher quotas and rate limits as described on the Pricing page. Specific limits depend on the selected tier (Pro, Ultra, Mega).
• Exceeding your monthly quota will cause subsequent API requests to return an HTTP 429 error until the next billing cycle.
• Exceeding your rate limit (requests per minute) will temporarily throttle your access. Persistent rate-limit violations may trigger an automatic temporary suspension.
• API responses are cached for a default duration (currently 3 hours). Paid plans may force a cache refresh at the cost of additional credits, as specified in the plan details.

We reserve the right to modify rate limits, quotas, or caching policies at any time. Material changes will be communicated via email or through an announcement on the website.

The WhoisJSON brand, logo, website design, API documentation, source code, and all associated intellectual property are the exclusive property of WhoisJSON and are protected by applicable copyright, trademark, and intellectual-property laws.

• You may not copy, reproduce, modify, distribute, or create derivative works from any part of the Service without prior written consent.
• The WHOIS, DNS, SSL, and domain-availability data returned by the API originates from public registries, certificate authorities, and DNS resolvers. WhoisJSON does not claim ownership of this raw data but does claim ownership of the structured format, enrichment, and presentation layer.
• You may not use the WhoisJSON name, logo, or trademarks in any manner that suggests endorsement, partnership, or affiliation without prior written authorization.

7.1 — Subscription & Payment

• Paid subscriptions are billed monthly in advance. Payment is processed securely through Stripe and PayPal.
• Prices are listed in USD and EUR. The applicable currency is selected at checkout and applies for the duration of the subscription.
• Subscriptions automatically renew at the end of each billing period unless cancelled before the renewal date.
• You may upgrade or downgrade your plan at any time. Upgrades take effect immediately; downgrades take effect at the start of the next billing cycle.
• All prices are exclusive of applicable taxes (VAT, sales tax, etc.). You are responsible for any taxes imposed by your jurisdiction.

7.2 — Cancellation

• You may cancel your subscription at any time from your account dashboard.
• Upon cancellation, your paid plan remains active until the end of the current billing period. After that, your account reverts to the free Basic plan.
• Unused API requests do not carry over to the next billing period and are not transferable.

7.3 — Refund Policy

• A verified prolonged service outage (exceeding 24 consecutive hours) attributable to WhoisJSON.
• A billing error caused by our payment system.
• Refunds will not be issued for account suspensions or bans resulting from violations of these Terms, including duplicate-account abuse.
• Refunds will not be issued because you did not use your full monthly quota.

Refund requests must be submitted within 14 days of the charge to support@whoisjson.com.

We target a 99.9% uptime for the WhoisJSON API, measured on a monthly basis. However, this is a target and not a guarantee. The Service may be unavailable due to:

• Scheduled maintenance (we aim to provide advance notice when possible).
• Unscheduled emergency maintenance to address security vulnerabilities or critical bugs.
• Force-majeure events including, but not limited to, natural disasters, acts of war, government actions, network outages, or third-party service failures.
• Changes to upstream WHOIS/RDAP registries, DNS resolvers, or certificate-authority systems that are outside our control.

We reserve the right to modify, suspend, or discontinue any feature, endpoint, or the entirety of the Service at any time with reasonable notice. Real-time API status is available on our API Status page.

• Account data: we collect your email address, hashed password, and payment information (processed and stored by Stripe/PayPal — we do not store card numbers).
• Usage data: we log API requests (timestamps, endpoints, queried domains, response codes, IP addresses) to enforce rate limits, detect abuse, and improve service quality.
• Analytics: we use Google Analytics to collect anonymized browsing data on the website.
• We do not sell, rent, or share your personal information with third parties for marketing purposes.
• We may disclose your data if required by law, court order, or governmental regulation, or to protect the rights, safety, or property of WhoisJSON, its users, or the public.
• You may request deletion of your account and associated data by contacting support@whoisjson.com. We will process such requests in accordance with applicable data-protection laws.

10.1 — By WhoisJSON

• Your use of the Service poses a security risk or threatens the stability of our infrastructure.
• Your account is involved in fraudulent, abusive, or illegal activity.
• You have failed to pay subscription fees when due.

In the event of a ban for Terms violations, no refund will be issued and any remaining subscription credit will be forfeited.
