Unified API data-models and methods
The modern Unified API+MCP platform, built differently
Real-time, pass-through
Every request hits the source API live. No caching or sync jobs: reads and writes go to the source API, and native and virtual webhooks report changes on supported integrations.
No customer records at rest
No customer records at rest; connection credentials and operational metadata are encrypted at rest. Each workspace runs in one region: US on every plan, EU or AU on Pro and Scale.
Common objects across every category
Unified objects, endpoints, scopes and errors across every category, plus raw payloads when you need vendor-specific fields.
Custom fields & objects
Read and write custom fields through the Metadata API; reach custom objects through raw fields and the Passthrough API.
AI-ready integrations
Built for AI products: Unified MCP gives LLMs scoped access to integration tools, with options to limit permissions and hide sensitive fields.
Predictable pricing, no lock-in
Usage-based pricing that scales with API volume, not with the number of customers you connect. Own your credentials and export them anytime; tokens issued to your own OAuth app keep refreshing after you leave.
