The Factagora API is one HTTP interface over the Temporal Knowledge Graph. Every endpoint takes the same fa_... key and returns JSON. For what FactBlocks and the TKG are, see What is Factagora?. This page is about picking the right endpoint. For request and response details, follow the links into the API Reference.

See Credits & Pricing for how usage is measured and what happens on failed requests.

​
Detect, then verify

Claim Detection and Fact Checker are meant to be used together. Detection takes a page of text and returns the sentences worth checking, each with a normalized_claim that resolves pronouns and references. Feed that into Fact Checker rather than the raw sentence, and the verdict has the context it needs. This is the same pipeline the DeepVerify extension runs.

​
Public data or your own

By default the APIs search Factagora’s public corpus. If you want answers grounded only in your own material, Ingest puts your URLs, text, or files into a private graph, and Fact Search reads it back with source=ingest. Collections goes further by merging many ingested documents into one corpus you can question directly.
