👋 Hey Product Hunt! We're launching Factagora API today — the fact-checking and research API we always wanted but couldn't find. 🚧 The Problem AI is advancing fast, but the hallucination problem persists. Most AI products have no verification layer. They just hope the model gets it right. If your product generates summaries, analysis, or decisions based on AI output — and accuracy matters — you've probably faced this: - No easy way to verify AI-generated claims against real sources - Building your own fact-checking layer from scratch - Stitching together multiple APIs for news, research, and evidence We hit these pain points building Factagora. So we decided to fix it. ✅ The Solution With a single API key, ground your AI in verified facts, evidence, and causal reasoning. 6 Purpose-Built Endpoints - News Search — Real-time news retrieval ranked by relevance and credibility - Fact Checker — Verify claims with TRUE / FALSE / UNCERTAIN + confidence score - Evidence Finder — Supporting and opposing evidence ranked by strength - Deep Research — Multi-source structured research report with citations - Timeseries — Extract time-ordered facts from any URL or document - Causality Graph — Auto-infer causal relationships from any document 💡 Who It's Built For - AI agents that need to verify claims before responding - Research tools that surface evidence for any topic - News and media platforms checking AI-generated content 🚀 Get Started Free Start with 100 free credits — no credit card required. 👉 https://enterprise.factagora.com...
