# Errors

> Shared error shape.

Public and internal APIs use a shared error envelope:

* `error.code`
* `error.message`
* `error.type`
* `request_id`

Runtime API errors are emitted by the platform gateway. Product APIs should preserve request ids and map product-owned commercial/session failures into the shared envelope.
