Core concepts
Key ideas to understand before integrating.
Sources & Auditing
Verifact verifies only against the sources you explicitly provide: registered sources, URI references, or inline text.
Claim Coverage
Understand how claims are supported by the sources you supply and how that affects verification and requirements-driven decisions.
Authorization
Configure requirements and options to map verified claims to a single, auditable decision (allow, deny, needs_review).
