x-harvested-from

`x-harvested-from` appears in the info block. Its value is a string. Used by 4 providers across 6 OpenAPI documents. Observed values include `Mintlify per-page OpenAPI slices on docs.gmicloud.ai/api-reference`, `https://api.sg.cosmose.co/deal-hunter-registration-api/v3/api-docs`, `https://cloud-api.refuel.ai/openapi.json`, `https://api.xr.health/v1/openapi.json`. Consistent with provenance — this is inferred from where the key appears and what it carries, not from any published definition.

Provenance derived description
How this description was produced. It is assembled from what was measured in the corpus — where this key appears in a document, what shape its value takes, the values observed, and how many providers use it. It is not taken from a published definition, because for most extensions none exists. Read it as evidence, not as a specification. If you own this extension and want it described properly, tell us.

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 provenance job.
