The API
One key, three endpoints.
Bearer auth, structured JSON responses, OpenAPI spec included. Works with any language and framework.
Full API referenceHow it works
Send a claim. Get a verdict you can cite.
One call returns a confidence-scored verdict, with the exact sources behind it, ready to ground your output.
Where it fits
Add one trust layer. Keep your stack.
No migration, no retraining. Factagora sits between your application and the stack you already run, and adds verification in a single call.
Data provenance
Where does this data come from?
Public data is available to everyone. What makes Factagora's data different is everything that happens after it arrives.
Split into atomic claims
We don't store documents whole. Every source is broken into individual claims and converted into FactBlocks: verifiable units that carry their own sources.
Run through the verification loop
Each claim gathers evidence, faces its strongest counterargument, and receives a verdict. Only what survives is recorded.
Timestamped into the ledger
Every verdict lands in the TKG, a knowledge graph built around time and causality. When verdicts change, the full trajectory stays on record.
DeepVerify verifies what AI says, in real time.
DeepStamp proves what AI took from your content.
