To audit API contracts for layer leakage, apply an architecture-level scanner to your API and service directories to identify cross-boundary violations and generate a penalty-based score with structured findings for remediation.

A penalty-based score in API contract auditing evaluates architectural integrity by calculating four metrics—compliance, completeness, quality, and implementation—based on detected issues like missing DTOs and inconsistent error contracts.

To check for missing or misused DTOs, run a domain-aware contract audit across your service directories to verify DTO presence and produce a domain-tagged report detailing completeness and quality scores.

Yes, API contract auditing supports domain-aware scans that analyze specific domain layers and write per-domain structured findings reports to your configured output directory for targeted remediation.

The best way to enforce consistent error contracts is to perform an architecture-level audit across service boundaries to detect pattern inconsistencies and generate a compliance score with a detailed domain-tagged report.
