DISCOVER — agent searches available services by vertical, location, time 2. QUOTE — agent receives price, availability, terms 3. INITIATE — agent starts transaction; funds held in escrow 4. APPROVE (optional) — user confirms if above threshold 5. CONFIRM — service provider accepts; booking locked 6. COMPLETE — service delivered; escrow released 7. DISPUTE / REFUND — triggered by agent or user within dispute window ### Authentication - API key per registered agent + user OAuth token for acting on behalf of users - Scoped permission tokens: read-only, transact-only, full-access - JWT-based session tokens with 1-hour expiry + refresh - IP allowlisting for server-to-server agents --- ## API Reference Base URL: https://api.geranexus.com/v1 ### Discovery - GET /services — List available services.
