### Connection Configuration

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `api_endpoint` | String | `https://api.minimax.chat` | MiniMax API base URL |
| `timeout` | Integer | 30000 | Connection timeout (ms) |
| `max_connections` | Integer | 100 | Connection pool size |
| `keep_alive` | Boolean | true | Connection reuse |
| `retry_count` | Integer | 3 | Max retry attempts |

### Request Flow

1. **Request Building**: Construct API payload with model parameters
2. **Connection Acquisition**: Get connection from pool
3. **Request Execution**: Send HTTP POST to MiniMax API
4. **Response Handling**: Parse JSON response stream
5. **Connection Release**: Return connection to pool

### Error Handling

| Error Type | HTTP Code | Action |
|------------|-----------|--------|
| `ConnectionTimeout` | 408 | Retry with backoff |
| `RateLimitExceeded` | 429 | Wait and retry |
| `ServerError` | 5xx | Retry with backoff |
| `AuthenticationError` | 401 | Fail fast, alert |
| `InvalidRequest` | 400 | Fail fast, log details |

## 2. Output Contracts Analysis

### Contract Schema

```json
{
  "output_contract": {
    "version": "1.0",
    "required_fields": [
      "content",
      "model",
      "usage",
      "finish_reason"
    ],
    "optional_fields": [
      "tool_calls",
      "citations",
      "metadata"
    ],
    "validation_rules": {
      "content": {
        "type": "string",
        "min_length": 0,
        "max_length": 128000
      },
      "usage": {
        "type": "object",
        "fields": ["prompt_tokens", "completion_tokens", "total_tokens"]
      },
      "finish_reason": {
        "type": "enum",
        "values": ["stop", "length", "content_filter", "tool_calls"]
      }
    }
  }
}
```

### Validation Pipeline

```
Raw Response → Schema Validation → Type Coercion → Contract Emit
     │              │                   │              │
     ▼              ▼                   ▼              ▼
  Parse JSON    Check Required    Normalize Types   Emit Valid
  or Stream     Fields Exist      to Contract      Output
```

### Contract Enforcement Points

| Stage | Validation | Action on Failure |
|-------|------------|-------------------|
| Pre-send | Request schema | Reject before API call |
| Post-receive | Response schema | Retry or fallback |
| Stream chunk | Partial schema | Buffer until complete |
| Final | Full contract | Return or error |

## 5. Integration Summary

### Component Interaction Matrix

| From \ To | MiniMax | Contracts | Retry | Observability |
|-----------|---------|-----------|-------|---------------|
| **MiniMax** | - | Provides raw response | Reports errors | Emits spans |
| **Contracts** | Validates input | - | Triggers retry on fail | Logs violations |
| **Retry** | Wraps calls | May re-validate | - | Counts retries |
| **Observability** | Instruments | Instruments | Instruments | - |
