## Cost Analytics

### Token Tracking

The system tracks token usage for cost estimation:

| Metric | Description |
|--------|-------------|
| Input Tokens | Tokens sent to LLM |
| Output Tokens | Tokens received from LLM |
| Total Tokens | Combined usage |
| Estimated Cost | Based on model pricing |

### Cost Breakdown

View costs broken down by:
- **Model** - Which LLM models were used
- **Provider** - OpenAI, Anthropic, etc.
- **Time Period** - Daily, weekly, monthly
- **Research** - Per-research costs

### Accessing Cost Analytics

1. Navigate to **Metrics** → **Costs**
2. View summary statistics
3. Filter by date range
4. Export data as needed

### Pricing Information

The system includes pricing data for common models:

```
GET /metrics/api/pricing
GET /metrics/api/pricing/<model_name>
```

## Rate Limiting

### Monitoring Rate Limits

View current rate limiting status for search engines:

1. Navigate to **Metrics** → **Rate Limiting**
2. See per-engine statistics

| Column | Description |
|--------|-------------|
| Engine | Search engine name |
| Current Wait | Active wait time |
| Success Rate | Percentage of successful requests |
| Total Requests | Request count |
| Last Updated | Most recent activity |

### Rate Limit Management

From the dashboard you can:
- View current rate limit estimates
- See learned optimal wait times
- Monitor success rates

For CLI management, see [CLI Tools](cli-tools.md#rate-limiting-cli).

## Link Analytics

### Domain Classification

The system classifies domains found in research:

| Category | Examples |
|----------|----------|
| Academic | arxiv.org, pubmed.gov |
| News | bbc.com, reuters.com |
| Government | .gov, .edu |
| Commercial | company websites |
| Reference | wikipedia.org |

### Link Statistics

View aggregate statistics:
- Total links discovered
- Unique domains
- Category distribution
- Top domains by frequency

### Accessing Link Analytics

1. Navigate to **Metrics** → **Links**
2. View domain breakdown
3. Filter by category
4. See classification summary

### Classification API

Classify domains programmatically:

```
POST /metrics/api/domain-classifications/classify
{
  "domains": ["example.com", "arxiv.org"]
}
```

## Star Reviews

### Rating Research Quality

Rate your research results to track quality over time:

1. Open a completed research
2. Click the star rating (1-5)
3. Optionally add feedback text

### Viewing Ratings

Navigate to **Metrics** → **Star Reviews** to see:
- Average rating across all research
- Rating distribution
- Recent ratings with feedback
- Trends over time

### Rating API

```
# Get ratings for a research
GET /metrics/api/ratings/<research_id>

# Submit a rating
POST /metrics/api/ratings/<research_id>
{
  "rating": 5,
  "feedback": "Excellent results"
}
```

## Troubleshooting

### No Metrics Showing

- Ensure you have completed at least one research
- Check that token tracking is enabled
- Refresh the page

### Cost Estimates Incorrect

- Verify model pricing is up to date
- Check provider is correctly identified
- Token counts may vary by model

### Rate Limiting Data Missing

- Run some searches to generate data
- Check the rate limiting CLI for status
