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. ### Who it is for - Developers building evidence-gathering workflows - Researchers automating repeatable event questions ## Features and coverage **Available on:** API - **Cited answers** Responses include references that can be inspected against the answer. - **JSON API** Integrate research into applications through a documented request-and-response workflow. - **Prepaid usage** Purchase request credits rather than assuming unlimited subscription queries. ## Workflows with FactsAI ### Gather evidence Ask a narrowly scoped factual question and review the cited primary material. ### Build an event checklist Keep the answer, citation dates and contract conditions together before using the result in a forecasting model. ## Pricing and total cost The public page lists $0.012 per request: Starter $12 for 1,000 credits, Growth $60 for 5,000 and Scale $120 for 10,000. ### Starter $12 - 1,000 credits ### Growth $60 - 5,000 credits ### Scale $120 - 10,000 credits **Access:** API access requires a key and available credits. ## Getting started 1. Read the request and response documentation. 2. Obtain a provider API key through the account workflow. 3. Start with a narrow question and inspect every material citation. ## Useful links ### What to check - Citations do not guarantee a correct synthesis. This is general research infrastructure, not a verified Polymarket integration or settlement feed.

Its usefulness depends on question design and source checking; answer quality was not benchmarked. Based on documented features, setup and access terms.
