Integrations

REST API#

Call Defacta from any backend, batch job, or serverless function. Send text, receive a structured JSON verdict. This is the most flexible way to embed verification into your own product - gate responses, log results, or trigger review.

MCP server#

Defacta speaks the Model Context Protocol, so agents and MCP-aware tools can call it as a native tool. Give an agent the ability to fact-check its own output before it acts - verification becomes just another step the model can take.

Browser extension#

Verify content in place while you browse. The extension runs Defacta against what you are reading and surfaces its findings inline - useful for research, editorial review, and spotting AI-written misinformation.
