+# Phase 16 Plan 03: Postman, SwaggerHub, RapidAPI Sources Summary
+
+API marketplace recon sources scanning public Postman collections, SwaggerHub API specs, and RapidAPI listings for hardcoded API keys in examples and documentation.
+
+## Task Results
+
+### Task 1: Postman and SwaggerHub sources
+- **Commit:** edde02f
+- **PostmanSource:** Searches via Postman internal search proxy (`/ws/proxy`) for key patterns in collection snippets
+- **SwaggerHubSource:** Two-phase: search public specs, then fetch each spec and scan for keys in example values, server URLs, security scheme defaults
+- **Tests:** 8 tests (Name, Enabled, Sweep with match, Sweep empty) for both sources
+
+### Task 2: RapidAPI source
+- **Commit:** 297ad3d
+- **RapidAPISource:** Scrapes public search result pages for key patterns in code examples and descriptions
+- **Confidence:** Set to "low" (HTML scraping is less precise than JSON API parsing)
+- **Tests:** 4 tests (Name, Enabled, Sweep with match, Sweep clean HTML)
+
+## Deviations from Plan
+
+None -- plan executed exactly as written.
+
+## Known Stubs
+
+None. All three sources are fully functional with real API endpoint patterns.
+
+## Self-Check: PASSED
