A fast, ordered methodology for assessing an API end to end — REST/GraphQL/gRPC/SOAP — so nothing gets skipped. Load when the target is an API (or recon found one), on "test this API", "checklist", methodology triage, or to confirm coverage before reporting. Signals: /api, swagger/openapi.json, GraphQL /graphql, gRPC, JSON/XML endpoints, a mobile/SPA backend.
