x-metaDescription
`x-metaDescription` appears in the info block. Its value is a string. Used by a single provider across 21 OpenAPI documents. Observed values include `Find quick answers to questions about the Vonage Account API in this reference g`, `Find quick answers to questions about the Vonage Application API (v2.0) in this `, `Find quick answers to questions about the Vonage Audit API in this reference gui`, `Find quick answers to questions about the Vonage Conversation API (v1.0) in this`. Consistent with data & schema semantics — 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 data & schema semantics job.
