TL;DR
Shipped 2 new paid x402 endpoints:
- /api/dev-portal-exposure ($0.0005) - probes 39 dev-portal/VCS-dotfile/debug-surface paths
- /api/page-typography ($0.0005) - audits webfont loading + typography quality
Both verified end-to-end. Catalog grew 177 -> 179 endpoints.
Why these 2 niches
Dev-portal exposure
No existing endpoint enumerates production-leaked /swagger-ui.html / /actuator / /.git/HEAD / /.env / /phpinfo.php paths. This new endpoint probes 39 such paths and classifies each as exposed+sensitive.
Web typography
No existing endpoint audits webfont FOIT/FOUT risk (font-display: swap), preconnect coverage, line-height sanity. This new endpoint parses inline @font-face rules + preconnect/preload hints + computes typography_score 0-100 A-F.
