description: Add the production base path alongside the sandbox one. Mercedes-Benz publishes only the
*_tryout sandbox document; the production path is the same path with the _tryout suffix removed. Recorded
as a DERIVATION — see sandbox/mercedes-me-sandbox.yml — not as a value read from a Mercedes-Benz document.

description: 'Add the API key security scheme the contract describes in prose but does not declare.
Every operation in the source document returns 401 "Failed to resolve API Key query parameter / Invalid
API Key", yet the document carries no securityDefinitions at all, so no machine can discover how to
authenticate. The parameter NAME is deliberately left as a variable: Mercedes-Benz does not publish
it in any machine-readable place we could read, and inventing one would be worse than leaving the
gap visible.'

MercedesBenzApiKey:
type: apiKey

name: REPLACE_WITH_PORTAL_DOCUMENTED_PARAMETER_NAME
description: Developer-portal API key for the subscribed product, passed as a query parameter.
The exact parameter name is documented only on developer.mercedes-benz.com, which is a client-rendered
SPA and cannot be read by a non-browser client. Obtain it from the product page before use.

note: No idempotency key on any write operation. A retried POST duplicates the effect.
