Use `page` and `page_size` query parameters. ## Error Handling The API uses standard HTTP status codes: - `200` Success - `201` Created - `400` Bad Request - `401` Unauthorized - `403` Forbidden - `404` Not Found - `429` Too Many Requests servers: - url: https://api.onetsolutions.net description: Production security: [] tags: - name: Authentication description: >- Login, passwordless authentication, MFA, OAuth providers, and token management. - name: Organizations description: >- Organization management, members, roles, modules, audit logs, and notification settings. - name: Projects description: Project management, team members, and project-scoped resources. - name: Compute description: >- Cloud instances, volumes, snapshots, backups, VPCs, firewalls, SSH keys, uptime monitors, and instance tasks. - name: Domains description: >- Domain availability, registration, transfers, DNS zones, DNS records, and TLD information. - name: Web Hosting description: >- cPanel-based web hosting, emails, databases, subdomains, FTP accounts, addon domains, and SSL certificates. paths: /v1/organizations/{organization_id}/projects/{project_id}/dns-zones/{id}/settings: put: tags: - Domains summary: '[DNS Settings] Update DNS zone settings' description: >- Update the configuration settings for a DNS zone.
