  title: API Evangelist enhancement overlay for the Avis Budget Group Rental Cars API 2.0.0
  version: 1.0.0

  The provider's spec is strong on examples and schemas but ships (a) an operationId on only one of nine
  operations, (b) no info.contact although x-api-owner names the Partner API Team mailboxes, (c) no
  externalDocs pointing at the portal, and (d) no tag descriptions. This overlay proposes stable snake_case
  operationIds (used by skills/ and mcp/), surfaces the contact and docs the provider publishes elsewhere on the
  same page, and adds a server-level note that the only documented host is staging. It never changes a path,
  parameter, schema or response. Apply with any Overlay 1.0.0 processor against
  openapi/_original/avis-budget-rental-cars-openapi.json.
