Must-Have Features for MVP
Stable facade with typed contracts (OpenAPI/GraphQL) and SDKs
Schema virtualization and field synthesis for missing capabilities
Policy-driven multi-path execution with health-based routing
Strong caching, ETags, and offline snapshots
Idempotency, exactly-once delivery, and deduplication
Real-time monitors with auto-rollback on vendor regressions
Changelogs and deprecation shields with proactive alerts
Per-connector SLOs and credits for downtime
⚠️ Potential Challenges
- Keeping parity with many vendor APIs and versions
- Legal/ToS considerations for headless or alternative paths
- Caching correctness and staleness control
- Cost control for fallback strategies
- Comprehensive monitoring to choose best path in real time
Risk Level: Moderate
🎯 Keys to Success
- Dramatically fewer integration incidents despite vendor churn
- Faster delivery—teams build to one contract, not many vendors
- Performance and cost gains from intelligent caching/routing
- Clear accountability via SLOs and observability
- Security/compliance-ready facade with audit trails
- Easy adoption with drop-in SDKs and proxy connectors
