DeepInquiry is an API of short factual claims. Every fact is returned with its sources, a gold, silver or bronze verification tier, a score from 0.0 to 1.0, and a signature that can be verified. Most fact data counts how many pages repeat a claim. But a claim that appears on many pages is often...

As answered by people managing FriendlyData and DeepInquiry.
DeepInquiry's answer:
Vercel Supabase PostgreSQL REST API with OpenAPI
DeepInquiry's answer:
DeepInquiry counts separate source groups, not pages. Before counting, sources are grouped by website, and by parent company for the websites we have mapped, so ten pages on one site count as one. Wikipedia, its mirrors and aggregators are set aside whenever a source of another kind exists. Every fact comes back with its sources, a gold, silver or bronze tier, a score from 0.0 to 1.0, and a signature that can be verified. The methodology page also says what the grouping does not catch: wire reprints, copied wording and shared studies.
DeepInquiry's answer:
Choose it if you need to see how a claim is supported, not only whether it is marked true or false. Each fact shows its sources and how many separate source groups stand behind it, so your application can set its own bar. The method is published at https://www.deepinquiry.ai/methodology, there is a free key with 500 requests a month, and the OpenAPI definition is at https://www.deepinquiry.ai/openapi.json.
DeepInquiry's answer:
Developers building products that show or check factual claims, such as research tools, educational and reference apps, and content and publishing tools. It is also for teams that need each fact to carry its sources and a signature they can verify.
DeepInquiry's answer:
A fact that appears on many pages is often one claim copied many times, and counting pages makes a weak claim look well supported. DeepInquiry was built to count the separate source groups behind each claim and show its work. It is made by Machine Accountability Corporation.
