Excerpt

Performing API Inventory and Discovery

When to Use

Mapping the complete API attack surface of an organization before a security assessment
Identifying shadow APIs deployed by development teams without security review
Discovering deprecated or zombie API versions that remain accessible but unmaintained
Finding undocumented API endpoints exposed through mobile applications, SPAs, or microservices
Building an API inventory for compliance requirements (PCI-DSS, SOC2, GDPR)

Do not use without written authorization. API discovery involves scanning network infrastructure and analyzing traffic.
