FactLens API gives developers a single way to add evidence checking to a product without building separate retrieval, transcription, media, and evaluation pipelines.
Send a written claim, transcript, audio file, or image based post. FactLens processes the input through the appropriate checking flow, gathers supporting evidence, evaluates the claim, and returns one structured response that is ready to use in an application.
Responses include the normalized claim, verdict, explanation, confidence, evidence strength, cited sources, provider details, response time, and current usage. Developers can also supply their own verdict identifiers and rules so the response fits an existing product interface or moderation system.
API keys are server issued and designed for backend use. Requests support request IDs for safe retries, usage tracking, and predictable error handling.
