/v1/* requests require two headers:
X-Tenant-Code: the human-readable tenant slug you received during registration.X-API-Key: the tenant-scoped API key (lowercasex-api-keyalso works).
Register a tenant
Use the public registration endpoint to provision a tenant, capture the generated slug, and store the one-time API key:X-Tenant-Code and X-API-Key, or pass them
directly when using the SDK client.
