+  End-to-end security assessment of a web API.

+  discovered surface for common web vulnerabilities and exposed secrets (url_vuln). Composes existing
+  workflows rather than duplicating their logic, so each stage stays independently reusable.

+description: API endpoint discovery
+long_description: |
+  Discovers API endpoints on a target web application.
+  Combines active crawling (katana, which parses JavaScript to surface referenced endpoints) with optional
+  brute-forcing of API routes (ffuf, using Assetnote's HTTP Archive apiroutes wordlist — the same real-world
+  route dataset kiterunner relied on). Discovered endpoints are probed with httpx to verify they are live and
+  fingerprint their technologies. The apiroutes wordlist also covers exposed API specification paths
+  (openapi/swagger); when one is found, the --spec option hands it off to nuclei, which parses the spec
+  (input-mode openapi) and DAST-fuzzes every documented endpoint with the correct method and parameters —
+  recovering the contextual testing kiterunner used to provide, using a maintained tool already in secator.
