x-example
`x-example` appears on operations and on schema objects and properties. Its value is a string. Used by 42 providers across 235 OpenAPI documents. Observed values include `POST /20160918/autonomousDatabases/<autonomousDatabaseId>/actio`, `POST /20160918/autonomousContainerDatabases/<autonomousContainerDatabase`, `1`, `6f0bece6-7df3-4da4-af02-5e7f16e5e6fc`. Consistent with mocking & testing — this is inferred from where the key appears and what it carries, not from any published definition.

Why this is not in OpenAPI
Extensions exist because a provider needed something the specification would not carry. Most of what they hold is not the API contract at all — it is operational metadata about the contract: documentation, lifecycle, policy, provenance, and now agents. That metadata is usually better placed alongside the contract, in an Overlay or an APIs.json index, than crammed inside it. See everything else doing the mocking & testing job.
