Understanding Test Types

Peer Similarity (Type 0)

Compares all submissions within a check against each other. Best for detecting copying between students in the same class.

Web Check (Type 1)

Searches 20+ billion web sources including GitHub, Stack Overflow, and public repositories for matching code.

Database Check (Type 2)

Deep analysis against our proprietary database with AI-generated code detection and cross-institution matching.

Error Responses

401 Unauthorized

Invalid or missing API key.
