Use this atlas to answer two separate questions: **what can Praxa do on its product surfaces**, and **what can your application call through a documented developer contract**. ```mermaid theme={null} flowchart LR Need["What do you need?"] --> Build["Build with Praxa"] Need --> Use["Use Praxa"] Build --> API["REST APIs and Playground"] Build --> Packages["SDK, CLI, and MCP contracts"] Build --> Federation["Memory federation"] Use --> Product["Praxa application capabilities"] Product --> Native["iOS, voice, on-device, and device context"] Product --> Cloud["Web, chat, agents, teams, and automations"] ``` A product capability is not automatically a public API. Follow the linked developer service when one exists. Keep Execution Fabric API keys, Integration Gateway OAuth tokens, and provider credentials in their documented boundaries. ## Developer services | Service | Availability | Surface | Authentication | Start | | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------- | -------------------------------------------------- | --------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Execution Fabric**

means it is reachable only in the documented opt-in, cohort, or sandbox. * **Partner preview** is not general availability. * **Deployment-specific** means your organization must operate or receive an Integration Gateway origin and OAuth flow. * **Qualification preview** means source and deployment exist, but authenticated production proof is still incomplete. Capabilities that are building, dark, parked, or removed are intentionally absent from the provided-capability catalog. See [Service status](/overview/service-status) for the public release model.
