防止操纵和假新闻 与 新闻空气污染指数

我们的API提供多种验证信号，包括出版商权威排名（OPR分数）、来源可信度指标、重复检测以识别内容回收，以及原始来源归属。这些工具帮助您过滤不可靠的来源，并专注于经过验证的新闻报道。

OPR是我们专有的出版商权威指标，以1-10分评分，基于编辑标准、事实核查历史、域名权威性和新闻声誉等因素。较高的分数表明更可靠的来源，帮助您自动过滤掉低质量或不可靠的出版商。

是的，使用source.rank.opr.min过滤器仅显示高于您选择的信任阈值的出版商的文章。将OPR最低值设置为7 可将结果限制为具有强大编辑标准的主要知名新闻机构。

Our duplicate detection identifies when the same content is republished across multiple sites, a common tactic in coordinated disinformation campaigns. Filter to is_duplicate=0 to see only original reporting and avoid amplified manipulative content.

是的，我们的故事聚类功能可以对相关文章进行分组并识别原始突发新闻源。这有助于您追溯新闻的主要来源，而不是依赖于未注明出处就重新打包内容的聚合器或网站。

For breaking news, we recommend combining is_breaking=1 with high OPR thresholds to get fast coverage from reliable sources. This balances speed with accuracy, reducing exposure to unverified early reports that often spread misinformation.

By analyzing publication patterns, source relationships, and content similarity across our database, you can identify suspicious coordination. Sudden spikes in similar content from low-authority sources often indicate manipulation attempts.

Fact-checkers, researchers, and media literacy educators use our API to study misinformation patterns, build verification tools, and create educational resources. Academic and non-profit pricing is available for qualifying organizations.
