+## Fact Checker
+
+### What it is
+A specialized tool that evaluates the truthfulness of statements using Jina AI's Grounding API technology.
+
+### What it does
+This block analyzes a given statement and determines its factuality, providing a detailed assessment that includes both a numerical score and a reasoned explanation for its conclusion.
+
+### How it works
+The block takes a statement and processes it through Jina AI's fact-checking system. It securely sends the statement to Jina's API, which analyzes the content and returns a comprehensive evaluation. The system then processes this evaluation to provide clear, actionable results about the statement's truthfulness.
+
+### Inputs
+- Statement: The text statement that needs to be verified for factuality
+- Credentials: Secure authentication details required to access the Jina AI service
+
+### Outputs
+- Factuality: A numerical score indicating how factual the statement is
+- Result: A simple true/false determination of the statement's factuality
+- Reason: A detailed explanation of why the statement was classified as true or false
+- Error: Any error messages that might occur during the fact-checking process
+
+### Possible use case
+A content moderation team could use this block to verify claims made in user-generated content on a social media platform. For example, if a user posts a statement about a historical event, the team could quickly check its accuracy before the content goes live. This helps maintain information integrity and combat the spread of misinformation.
+
+### Additional Notes
+- The block is categorized under the SEARCH category, indicating its role in information verification and retrieval
+- It utilizes secure API authentication to ensure reliable and authorized access to the fact-checking service
+- The system provides both quantitative (factuality score) and qualitative (reason) assessments, offering a comprehensive evaluation of each statement
