Use Case Recommendations
Best for: Factagora
Factagora is a verification layer you call before your model's answer reaches a user. Three core endpoints sit behind one bearer-authenticated key with an OpenAPI spec: GET /fact-search returns ranked, cited results from verified sources for a query; POST /fact-checker takes a claim and returns a verdict with a confidence score plus the exact source documents behind it; POST /evidence-finder surfaces both supporting and opposing evidence ranked by strength, which is the endpoint that matters when a question is genuinely contested rather than simply true or false. Additional APIs cover deep research, timeseries, causality graphs and a fingerprint family for embedding, detecting and reporting on content provenance. The architectural claim is that it is additive: Factagora sits between your application and whatever LLM, vector database or RAG stack you already run, so adoption is one call rather than a migration or a retrain. The vendor's structure is a temporal knowledge graph of FactBlocks rather than a vector store, with source credibility scored explicitly, and its published case study is a top-five Korean law firm that restructured over 350,000 documents into it. A free playground with welcome credits lets you test before wiring anything in. Adjacent products in the same family include a DeepVerify browser extension and a DeepStamp provenance mark, and a playground lets you exercise the endpoints in the browser before writing any integration code.
Ideal use cases:
- •Teams or individuals who need confidence-scored claim verdicts returned with the exact source documents
- •Teams or individuals who need evidence finder surfaces opposing as well as supporting evidence, ranked by strength
- •Teams or individuals who need drops in front of any existing llm, vector db or rag stack — one call, no migration
- •Teams or individuals who need temporal knowledge graph of factblocks with explicit source-credibility scoring
- •Anyone focused on fact-checking workflows
