# SYNTHESIZED_PATH_PARAM_KEY

**Kind:** Constant

**Source:** [`atloria-monorepo/libs/parser-core/src/openapi/path-parameters.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/parser-core/src/openapi/path-parameters.ts#L33)

Marks a parameter that exists only because the URL demanded one.

Kept honest on purpose: a bare `{type: string}` recovered from the path template makes an
endpoint usable where the alternative is unusable, but it carries none of the type or prose a
parser reading the source could have supplied. Anything wearing this key is a gap in a
parser, and the count of them is the metric that says so.
