Include your JWT token in the Authorization header: ``` Authorization: Bearer YOUR_JWT_TOKEN ``` Tokens can be obtained from your Xerobi account dashboard. ## Versioning All requests must include the `Hixe-Version` header with the API version date (format: YYYY-MM-DD). Current version: `2026-01-01` ## Rate Limiting - Consumer endpoints: 100 requests per minute - Business endpoints: 1000 requests per minute Rate limit information is included in response headers: - `X-RateLimit-Limit`: Maximum requests allowed - `X-RateLimit-Remaining`: Requests remaining in current window - `X-RateLimit-Reset`: Unix timestamp when the limit resets version: '2026-01-01' contact: name: Xerobi API Support email: support@xerobi.com url: https://support.hixbe.com license: name: Proprietary url: https://hixbe.com/terms servers: - url: https://api.hixbe.com/fiber description: Production API security: - bearerAuth: [] tags: - name: Consumer description: Endpoints for residential customers - name: Business description: Endpoints for enterprise clients paths: /business/ip/assignments: get: tags: - Business summary: List all business IP assignments description: >- Returns all IP addresses and ranges assigned to the authenticated business account, including their status and reverse DNS configuration. **Use Cases:** - Inventory management of IP assets - Audit IP allocation - Configure reverse DNS records - Network planning and documentation operationId: listBusinessIPAssignments parameters: - $ref: '#/components/parameters/hixeVersionHeader' responses: '200': description: Successfully retrieved IP assignments content: application/json: schema: type: array items: $ref: '#/components/schemas/BusinessIPAssignment' example: - ip: 198.51.100.0/24 status: active rdns: mail.example.com assigned_date: '2025-06-15' type: ipv4 - ip: 2001:db8::/48 status: active rdns: null assigned_date: '2025-06-15' type: ipv6 '401': $ref: '#/components/responses/UnauthorizedError' '403': $ref: '#/components/responses/ForbiddenError' '429': $ref: '#/components/responses/RateLimitError' components: parameters: hixeVersionHeader: name: Hixe-Version in: header description: 'API version in YYYY-MM-DD format.
