+# API Endpoint Parameters Analysis
+
+## Overview
+
+This document analyzes multiple OpenAPI schema files (`schema/manage.json` and `schema/infra.json`) to identify parameter usage patterns across all API endpoints in the Cisco ND collection and assess the appropriateness of the endpoint mixin structure defined in `plugins/module_utils/ep/endpoint_mixins.py`.
+
+## Key Findings
+
+### Manage API (manage.json)
+
+#### Maximum Query Parameters: 7
+
+Two endpoints have the maximum of 7 query parameters:
+
+1. **GET /anomalyRules/systemTelemetryRules**
+   - Query parameters: `max`, `offset`, `pathAnomalyCategory`, `pathApplicablePlatforms`, `sort`, `status`, `title`
+
+2. **GET /inventory/switches**
+   - Query parameters: `fabricName`, `filter`, `hostname`, `max`, `offset`, `sort`, `switchId`
+
+#### Maximum Path Parameters in Manage: 1
+
+All endpoints use at most 1 path parameter. Examples:
+
+- `DELETE /fabrics/{fabricName}/switches/{switchId}`
+- `GET /fabrics/{fabricName}/policies/{policyId}`
+- `PUT /fabrics/{fabricName}/resourceGroups/{groupId}`
+
+#### Endpoints with Parameters
+
+- Total manage.json endpoints: 146
+- Endpoints with parameters: 18 (12%)
+- Total unique parameters: 18
+- Zero overlap with infra.json parameters
+
+### Infrastructure API (infra.json)
+
+#### Maximum Query Parameters: 4
+
+The endpoint `GET /cluster/nodes` has the maximum of 4 query parameters:
+
+- Query parameters: `nodeName`, `nodeBootstrapState`, `nodeOperationalState`, `nodeRole`
+
+#### Maximum Path Parameters in Infra: 1
+
+All endpoints use at most 1 path parameter. Examples:
+
+- `/backups/schedules/{name}`
+- `/aaa/localUsers/{pathLoginId}`
+- `/cluster/nodes/{pathNodeName}`
+
+#### Endpoints with Parameters
+
+- Total infra.json endpoints: 195
+- Endpoints with parameters: 75 (38%)
+- Total unique parameters: 31
+- Zero overlap with manage.json parameters
+
+### Cross-API Comparison
+
+| Metric | manage.json | infra.json | Difference |
+| ------ | -------- | -------- | -------- |
+| Total endpoints | 146 | 195 | +49 (34%) |
+| Unique parameters | 18 | 31 | +13 (72%) |
+| Avg query params/endpoint | 0.06 | 0.13 | 2.2x higher |
+| Avg path params/endpoint | 0.07 | 0.11 | 1.6x higher |
+| Max query parameters | 7 | 4 | — |
+| Max path parameters | 1 | 1 | — |
+| Parameter sparsity | 88% endpoints have zero parameters | 62% endpoints have zero parameters | — |

+| Total endpoints | 195 |
+| Endpoints with parameters | 75 (38%) |
+| Query param minimum | 0 |
+| Query param maximum | 4 |
+| Query param average | 0.13 per endpoint |

+
+## Analysis
+
+**Manage API** is highly focused:
+
+- Only 12% of endpoints use parameters
+- When parameters are used, they are specialized (filtering, pagination, sorting)
+- Clear separation between resource identification (path) and query/filtering (query)
+
+**Infrastructure API** has broader parameter usage:
+
+- 38% of endpoints use parameters (3x more than manage)
+- Parameters span multiple domains: AAA/authentication, cluster management, external integrations
+- Path parameters dominate over query parameters (11% vs 13% average usage)
+- Greater parameter diversity reflects complex multi-tenant and integration scenarios
+
+## Parameter Sharing Analysis
+
+To assess the granularity of the endpoint mixins, we analyzed how parameters are shared across endpoints in both schemas and compared them with the current mixin definitions.
+
+### Top Parameters by Reuse Across All APIs
+
+| Rank | Parameter | API | Count | Type | Has Mixin | Domain |
+| ---- | ----------- | ------- | ------- | ------- | ----------- | ----------- |
+| 1 | `name` | infra.json | 12 | path | ✗ MISSING | Generic resource identification |
+| 2 | `pathLoginId` | infra.json | 6 | path | ✓ LoginIdMixin | AAA/user management |
+| 3 | `fabricName` | manage.json | 19 | query | ✓ FabricNameMixin | Fabric management |
+| 4 | `ruleName` | manage.json | 5 | query | ✗ MISSING | Anomaly rules |
+| 5 | `forceShowRun` | manage.json | 4 | query | ✓ ForceShowRunMixin | Configuration |
+| 6 | `pathDomain` | infra.json | 3 | path | ✗ MISSING | AAA/login domain |
+| 6 | `pathSecurityDomain` | infra.json | 3 | path | ✗ MISSING | Security domain |
+| 6 | `pathApiKeyID` | infra.json | 3 | path | ✗ MISSING | API key management |
+| 6 | `pathKeyId` | infra.json | 3 | path | ✗ MISSING | Security key management |
+| 6 | `networkView` | infra.json | 3 | query | ✗ MISSING | IPAM integration |
+| 6 | `subnet` | infra.json | 3 | query | ✗ MISSING | IPAM filtering |
+| 12+ | Various others | both | 1-2 | mixed | ✗ Mostly MISSING | Domain-specific |
+
+### Key Observation: Mixin Coverage
+
+**Actual mixin usage:**
+
+- ✓ **LoginIdMixin**: ACTIVELY USED in `ep_api_v1_infra_aaa.py` (6 endpoints)
+  - Python field name: `login_id`
+  - Schema parameter: `pathLoginId`
+  - Confirmed usage for AAA user management
+
+- ✓ **FabricNameMixin**: Designed for manage.json (19 endpoints)
+  - Expected usage in fabric management endpoints
+
+- ✓ **ForceShowRunMixin**: Designed for manage.json (4 endpoints)
+  - Configuration operation flag
+
+**Unused mixins (0 endpoints each):**
+
+- ClusterNameMixin
+- HealthCategoryMixin
+- InclAllMsdSwitchesMixin
+- LinkUuidMixin
+- NetworkNameMixin
+- NodeNameMixin
+- SwitchSerialNumberMixin
+- VrfNameMixin
+
+These 8 unused mixins lack corresponding parameters in either manage.json or infra.json schemas.
+
+### Missing Parameters and Future Mixin Candidates

+
+- `name` (12 endpoints) - Generic resource identifier (backups, clusters, schedules)
+  - Candidate: **NameMixin**
+
+- `pathLoginId` (6 endpoints) - User login identification
+  - Status: ✓ **LoginIdMixin already exists and is used**
+  - Location: `ep_api_v1_infra_aaa.py`
+
+- `pathDomain` (3 endpoints) - AAA login domain
+  - Candidate: **PathDomainMixin**
+

+  - Candidate: **RuleIdMixin**
+
+- `policyId` (3 endpoints) - Policy identification
+  - Candidate: **PolicyIdMixin**
+
+- `policyGroupId` (3 endpoints) - Policy group identification
+  - Candidate: **PolicyGroupIdMixin**
+
+- `switchId` (3 endpoints) - Switch identification
+  - Candidate: **SwitchIdMixin**
+
+### Coverage Assessment - Combined APIs
+
+| Metric | Value |
+| ------ | -------- |
+| Total endpoints (both APIs) | 341 |
+| Total unique parameters (both APIs) | 49 |
+| Parameters with existing mixins | 3 (6%) |
+| Endpoints covered by existing mixins | 29 (8.5%) |
+| Parameters without mixins | 46 (94%) |
+| Gap to close with new mixins | 91.5% |
+
+**Key Finding:** Only 3 of 11 defined mixins are actually used (LoginIdMixin, FabricNameMixin, ForceShowRunMixin). The 8 unused mixins (ClusterNameMixin, HealthCategoryMixin, InclAllMsdSwitchesMixin, LinkUuidMixin, NetworkNameMixin, NodeNameMixin, SwitchSerialNumberMixin, VrfNameMixin) have no corresponding parameters in either schema.
+
+## Conclusion: Mixin Granularity Assessment
+
+### Overall Assessment
+
+**The current mixin structure is partially aligned with actual schema usage.** Three mixins are actively used (LoginIdMixin, FabricNameMixin, ForceShowRunMixin), but 8 mixins are unused and lack corresponding parameters in either schema.
+
+### Detailed Findings
+
+1. **LoginIdMixin is actively used** ✓
+   - Confirmed usage in `ep_api_v1_infra_aaa.py`
+   - 6 endpoints in infra.json
+   - Maps Python `login_id` to schema `pathLoginId`
+   - Well-justified for AAA/user management
+
+2. **FabricNameMixin is well-justified** ✓
+   - 19 endpoints in manage.json (13% of manage API)
+   - High reuse across fabric management endpoints
+   - Cross-domain usage justifies a dedicated mixin
+
+3. **ForceShowRunMixin is justified** ✓
+   - 4 endpoints in manage.json (2.7% of manage API)
+   - Specialized boolean flag pattern
+   - Benefits from consistent validation and documentation
+
+4. **8 unused mixins need review** ⚠️
+   - ClusterNameMixin, HealthCategoryMixin, InclAllMsdSwitchesMixin, LinkUuidMixin, NetworkNameMixin, NodeNameMixin, SwitchSerialNumberMixin, VrfNameMixin
+   - No corresponding parameters found in manage.json or infra.json
+   - Possible reasons:
+     - Designed for future APIs (analyze.json, orchestration.json, one_manage.json)
+     - Legacy code from earlier API versions
+     - Placeholder definitions awaiting implementation
+
+5. **Parameter naming convention discovered**
+   - Python mixins use snake_case: `login_id`, `fabric_name`
+   - Schema uses camelCase with path prefix: `pathLoginId`, `fabricName`
+   - This suggests an automated field serialization/aliasing mechanism exists
+
+6. **Zero parameter overlap between APIs**
+   - manage.json and infra.json are separate API subsystems
+   - No shared parameters except by semantic similarity
+   - Suggests different architectural boundaries or evolution
+
+### High-Priority Mixin Candidates
+
+Based on parameter reuse patterns:
+
+**Infrastructure API (3+ endpoints):**
+
+- **NameMixin** (12 endpoints) - Generic resource identifier
+- **PathDomainMixin** (3 endpoints) - AAA login domain
+- **PathSecurityDomainMixin** (3 endpoints) - Security domain
+- **PathApiKeyIdMixin** (3 endpoints) - API key management
+- **PathKeyIdMixin** (3 endpoints) - Security key management
+- **NetworkViewMixin** (3 endpoints) - IPAM integration
+- **SubnetMixin** (3 endpoints) - IPAM filtering
+
+**Manage API (3+ endpoints):**
+
+- **RuleNameMixin** (5 endpoints) - Anomaly rule filtering
+- **RuleIdMixin** (3 endpoints) - Anomaly rule identification
+- **PolicyIdMixin** (3 endpoints) - Policy identification
+- **PolicyGroupIdMixin** (3 endpoints) - Policy group identification
+- **SwitchIdMixin** (3 endpoints) - Switch identification
+
+### Recommendations
+
+1. **Investigate the 8 unused mixins**: Determine if they are for planned APIs (analyze.json, orchestration.json, one_manage.json) or should be removed
+
+2. **Verify naming convention**: Document the mapping between Python field names (snake_case) and schema parameter names (camelCase with path prefix)
+
+3. **Prioritize new mixins for high-reuse parameters**: Focus on NameMixin (12 endpoints) and the path-based parameters in infra.json (3+ endpoints each)
+
+4. **Consider parameter categorization**: Group new mixins by domain (AAA/Auth, IPAM, Anomaly Rules, etc.) for better code organization
+
+5. **Document mixin scope**: Clarify which mixins are for which APIs (manage vs. infra vs. future APIs) to guide future development
