Competitor Landscape
- Apigee/Kong/Tyk (generic gateways)
- Gravitee
- Celigo/Workato (iPaaS, not API augmentation)
- UiPath/Automation Anywhere (RPA, not domain virtual API)
Must-Have Features for MVP
Virtual API layer with capability negotiation and versioning
Durable write queue with exactly-once reconciliation
Rate-limit smoothing and backoff policies
Fallback adapters: UI automation, file-drop, email, read-only DB
Sandbox verifier and audit logging
Circuit breakers and global kill-switch
SDKs for JS/Java/.NET with typed models
⚠️ Potential Challenges
- ERP EULAs or governance may restrict UI automation
- Screen changes can break RPA flows
- Security review for DB or file-drop access
- Change management to adopt a virtualized API
Risk Level: High
🎯 Keys to Success
- >99% success rate on virtualized endpoints during vendor outages
- 50% reduction in integration lead times caused by API gaps
- Zero data divergence post-commit as verified by reconciler
- Defined SLOs achieved for latency and durability
