x-practice-access
`x-practice-access` appears on operations. Its value is a string. Used by a single provider across 1 OpenAPI document. Observed values include `share_patients" need to be set for data access among practice`, `Data access among practice is available`, `share_appointment_profiles" need to be set for data access`, `share_consent_forms" need to be set for data access among`. 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.
Work with this as data
Every extension here is available over the APIs.io API and to AI agents over MCP. OpenAPI Extensions is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
