What is FactsAI?

FactsAI is a general research API that returns source-linked answers for applications and agents. A prediction-market researcher can use it to gather evidence around an event before mapping that evidence to the contract’s exact conditions.

It is not a Polymarket order endpoint or an oracle. The integration work is deciding which question to ask, validating the cited material and preserving the date of the evidence.
