/costco/product/{id}/availabilityPath parameters:
id (required) — a Costco product id.Query parameters:
postal_code (required) — US destination ZIP code.state (required) — US destination two-letter state code.Notable response behavior:
availability/available_for_sale reflect real-time stock status for
the given destination, distinct from /costco/product/{id}'s
buyable flag (which is a general purchase-eligibility flag, not
destination-specific).estimated_delivery_date and supplier_available_date are ISO 8601
timestamps (no timezone offset — Costco returns these as local
wall-clock dates).id, postal_code, or state returns 400 before any
