Praxa Capability Atlas

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.

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.

Beta 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.

Capabilities that are building, dark, parked, or removed are intentionally absent from the provided-capability catalog. See Service status for the public release model.
