# Dependencies API

> Provides dependency analysis for software components, including direct and transitive dependency resolution.

## TransitiveDependencies

Get the full transitive dependency tree for software components, including both direct and indirect dependencies.

> All components in a request must belong to the same ecosystem. Mixing ecosystems (e.g., npm and Maven) results in a validation error.

### Request Format

* `depth` (optional) — Maximum number of dependency levels to traverse
* `limit` (optional) — Maximum number of dependencies returned

### HTTP Request Example

```bash theme={null}
curl -X POST 'https://api.scanoss.com/v2/dependencies/transitive/components' \
  -H 'Content-Type: application/json' \
  -H "X-Api-Key: $SC_API_KEY" \
  -d '{
    "depth": 3,
    "limit": 50,
    "components": [
      {"purl": "pkg:npm/express", "requirement": "4.18.0"},
      {"purl": "pkg:npm/lodash", "requirement": "4.17.0"}
    ]
  }' | jq
```

### Response Format

Returns resolved transitive dependencies for the requested components.

* `dependencies`: List of direct and transitive dependencies
* `status`: Request outcome (success or failure)

Each dependency includes:

* `purl`: Dependency Package URL
* `version`: Resolved version
* `requirement`: Version constraint that resolved the dependency

### Response Examples

#### Complete Transitive Analysis

  }
}
```

#### Component with No Dependencies

```json theme={null}
{
  "dependencies": [],
  "status": {
    "status": "SUCCESS",
    "message": "Transitive dependencies successfully retrieved"
  }
}
```
