What It Is

rss2json.com is an online RSS-to-JSON converter and API service for developers. Its core value is converting traditional RSS feeds into JSON structures that are easier for frontends, backends, or scripts to consume. It is suitable for use cases such as news aggregation, blog list rendering, and community content fetching. Its documentation also positions it as a Google Feed API alternative.

Core Features and Developer Experience

The service provides a GET endpoint at https://api.rss2json.com/v1/api.json. The required parameter is rss_url, which should contain an escaped RSS feed URL. The response includes feed metadata such as title, link, author, description, and image, as well as an items array. Each item includes fields such as title, publication date, link, GUID, author, thumbnail, description, content, enclosure, and categories.

For enhanced functionality, it supports api_key, sorting by pubDate, author, or title, setting ascending or descending order, limiting the number of returned items, and JSONP callback. Note that parameters such as sorting and count require an API Key. The documentation provides a jQuery Ajax example and a sample successful response, so the learning curve is low. The page also lists entry points for JavaScript, PHP, Ruby, and Python examples, but the crawled content does not show the full code.

Pricing and Openness

The crawled content shows that the site has Plans and Available plans pages, but it does not include specific pricing, free quota, request limits, or payment method information. As a result, its long-term usage cost cannot be determined. The content also does not state whether it is open source or supports self-hosting, and there is no visible mention of official SDKs, SLA, or enterprise support.

Pros, Cons, and Best-Fit Users

The advantages are a simple API, a straightforward response structure, the ability to convert RSS to JSON without complex integration, and support for legacy frontend integration methods such as JSONP. The drawbacks are that the public documentation is relatively limited, with no detailed error codes, rate limits, caching strategy, availability commitments, or plan descriptions. It is suitable for individual developers, small websites, or prototype projects that need quick access to RSS content. For high-frequency production systems, it is advisable to confirm quotas, stability, and paid terms first.

Access from China and Alternatives

The crawled content does not make it possible to determine accessibility from mainland China, so it is marked as unknown; payment methods are also not disclosed. If access or stability is limited, alternatives include self-hosting an RSS parsing service, using Feedparser-style libraries in various programming languages, or evaluating RSSHub and other RSS-to-JSON APIs.
