Purpose focused API version deprecation auditing
This tool targets API version deprecation audits by mapping your live endpoints against documented contract changes. It compares the submitted URL against common versioning patterns and flags endpoints that appear to be legacy or deprecated based on path characteristics and spec definitions. The scanner reports what it observes without attempting to modify or block traffic.
Spec driven discovery and cross reference
OpenAPI analysis parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution. The scanner cross references spec definitions against runtime behavior to surface undefined operations, deprecated paths, and missing pagination. This helps you verify that advertised contracts remain consistent with actual responses across versions.

Detection coverage for deprecation signals
The scanner evaluates 12 categories aligned to OWASP API Top 10 to surface deprecation related risks. It identifies inventory management issues such as missing versioning and legacy path patterns, input validation anomalies like dangerous HTTP methods, and data exposure through verbose error traces. Findings are reported with prioritized remediation guidance.
- Authentication bypass and JWT misconfigurations
- BOLA and IDOR via sequential ID probing
- Data exposure including PII and API key patterns
- Unsafe consumption through excessive third-party URLs
- LLM security probes across multiple tiers
Operational constraints and transparency
Scan time remains under a minute using read-only methods (GET and HEAD) plus text-only POST for LLM probes. The scanner does not fix, patch, block, or remediate. It does not perform active SQL injection or command injection, and it does not detect business logic vulnerabilities that require domain specific understanding. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers.
Integrations for continuous deprecation tracking
Use the CLI to run audits on demand with JSON or text output. The web dashboard supports scan tracking, score trends, and downloadable compliance PDFs. For CI/CD pipelines, the GitHub Action can gate builds based on score thresholds. The MCP server enables scanning from AI coding assistants, and the Pro tier adds scheduled rescans and diff detection to track regressions over time.
