Data Plane

The data plane is the execution layer that processes API requests. It handles chat completions, audio generation, and transcription through a canonical path that includes:

• Authentication — API key verification
• Routing — Selecting the best available provider account
• Execution — Calling the upstream provider
• Metering — Recording usage metrics
• Quota enforcement — Checking workspace limits

Product API vs User App

Both the Product API (/v1/*) and the User App (/me/v1/*) use the same data plane. The User App is a BFF (Backend-For-Frontend) that authenticates with cookies and resolves an internal API key, then calls the same canonical execution path.

This means:

• Same routing semantics
• Same quota and metering
• Same conversation behavior
• Same provider errors
