What It Is

RKNWEB is a monitoring and lookup service built around the public registries of Russia’s Roskomnadzor (RKN). It reorganizes official open registries into a more readable web format and lets users check whether a website appears on relevant regulatory lists. Its coverage includes registries for blocked websites, organizers of information dissemination, foreign agents, audiovisual services, and more.

Core Features and Developer Capabilities

From a developer-tooling perspective, RKNWEB’s main value is its machine-readable data. Its API v3 provides JSON output, with the Base URL rknweb.ru/api/v3/. Endpoints include blocked domains, IPs currently listed in the registries, ORI websites, news aggregators, and audiovisual service lists. Requests support GET or POST. Successful requests return 200, while failures return a 500 error JSON. The website also offers form-based lookup and a Telegram bot that can subscribe to domain status change notifications.

Data, Documentation, and Ecosystem

The site emphasizes that its data comes directly from Roskomnadzor’s official public sources and is processed into a format that is easier to read and reuse. The API documentation is sufficient for basic integration: it lists endpoints, update frequency, and response examples. However, it still falls short for serious production integrations—for example, there are no field definitions, pagination details, rate limits, authentication guidance, version-compatibility notes, SLA information, or detailed error-code explanations. On the ecosystem side, only a Telegram Bot is explicitly mentioned, with no SDKs or integrations for mainstream development frameworks.

Pricing and Sustainability

The API description states that the data can be used freely and at no cost, and there are no paid plans or payment methods shown. However, a blog announcement in the main text says that maintenance of the blocked websites registry will stop on 2026-02-25 and that the API will be fully discontinued. This is a major availability risk. If the announcement is accurate, RKNWEB should not be used as the sole dependency for production systems.

Pros, Cons, and Who It’s For

Its strengths are a focused use case, clear data sources, a simple API, free access, and support for notification workflows. Its weaknesses are that it only applies to Russian RKN registries, historical data capabilities are not evident, documentation and support are limited, and there is a risk of service discontinuation. It is suitable for webmasters, operations teams, compliance teams, and developers who need to monitor Russia-related access and compliance status.

Access from China and Alternatives

The site does not provide information about access from mainland China, network connectivity, or payment options, so its availability from China can only be marked as unknown. For critical business use, it is advisable to also prepare Roskomnadzor’s official public registries, a self-built crawling workflow, or other network blocking and compliance monitoring services as alternatives and backups.
