JsonWhois is a Whois and screenshot API service for developers. The captured page is mainly the pricing page, and the navigation includes entries such as Docs, Whois, Download Newly Registered Domains, Bulk Whois, Pricing, and Signup. This suggests that the product is not just a simple web-based tool, but is positioned around API-driven or callable capabilities for programmatic domain lookups, bulk Whois, and website screenshots.
Based on the page content, JsonWhois’s core capabilities include Whois Calls, Screenshots, Bulk Whois, and downloads of newly registered domains. It also provides usage stats, allowing users to review usage and predict whether they need to adjust their subscription. This is important for developer tools billed by call volume. On the support side, the page mentions experts in PHP, NodeJS, Python, and other technologies, but this only indicates the technical background of the support team and should not be taken as evidence of official SDKs. Although there is a Docs navigation item, the captured content does not show API endpoints, authentication methods, response structures, rate limits, or error code documentation, so it is difficult to fully assess the maturity of the API and the quality of the documentation.
The pricing model lets users choose monthly volumes for Whois Calls and Screenshots, with custom plans also supported. All paid plans include burst queries after the included quota is exceeded: overage for Whois lookup is $0.01 per query, and overage for screenshot is $0.02 per query. These overage rates are disclosed clearly, but the page does not display the specific base plan prices or quota ranges. The payment section includes Add Card, Card Number, Expiration Date, and CVV, indicating that bank card or credit card payments are supported at minimum.
The main advantages are a clear product scope focused on two common developer needs—domain Whois and screenshots—transparent overage billing, and usage management features that help control costs. The drawbacks are that public information is relatively limited, with no clear details on SDKs, examples, SLA, data sources, privacy compliance, or service stability. There is also no information on whether it is open source or supports self-hosting.
JsonWhois is suitable for scenarios such as domain asset management, risk control, security intelligence, bulk domain due diligence, and website screenshot archiving. The page does not provide information about access from China, so it is recommended to test network connectivity and credit card payment availability in practice. For alternatives, you can compare it with WhoisXML API, DomainTools, and SecurityTrails; for screenshot needs, ScreenshotOne or urlscan.io may also be worth evaluating.
