Malformed request

Media typeapplication/json

The JSON body returned for every error response: { "error": "<message>" }, optionally with a stable machine code ({ "error": ..., "code": ... }). The code lets clients map an error to their own localized copy instead of showing the English error string; it is present only for errors we’ve assigned a stable code, and omitted otherwise.

object

code

Stable machine-readable error code for client-side localization, when one is defined for this error (e.g. key_not_found, algorithm_not_on_plan).

string | null

error

required

Human-readable error message. Never contains internal/driver detail.
