Your AI can generate confident-sounding lies. Factagora API lets you catch them.
The Problem
LLMs hallucinate. They state false claims with high confidence, cite sources that don't exist, and have no way to verify themselves. If you're building AI products agents, assistants, research tools you're shipping unverified outputs every day.
Building a verification layer from scratch means ML infrastructure, credibility scoring, news pipelines, and causal reasoning. Most teams skip it. That's the problem Factagora solves.
