Boulevard GraphQL APIs
Boulevard exposes two distinct, confirmed GraphQL surfaces plus one adjacent REST endpoint. All three require an Enterprise-tier Boulevard account and are provisioned through the Boulevard Developer Portal with a sandbox `businessId` (URN-formatted, e.g. `urn:blvd:Business:{id}`) and `apiKey`, sent as a Bearer token in the `Authorization` header.
