## API Pattern

G2 follows the JSON:API specification (https://jsonapi.org/):
- Responses use `data`, `attributes`, `relationships`, `meta` structure
- Pagination: `page[number]` and `page[size]` query parameters
- Filtering: `filter[field]=value` query parameters
- Reviews returned newest-first by default (10 per page default)

## Key Metrics

### Review Metrics
- `star_rating` - Overall star rating
- `title` - Review title
- `comment_answers` - Structured review responses (likes, dislikes, recommendations)
- `submitted_at` - Review submission date
- `is_public` - Whether the review is publicly visible

### Product Metrics
- `name` - Product name
- `slug` - URL slug on G2
- `avg_rating` - Average star rating
- `total_reviews` - Total review count
- `category` - G2 category placement

### Buyer Intent (Tracking)
- `company_name` - Visiting company name
- `page_visited` - G2 page URL visited
- `visited_at` - Visit timestamp
- `activity_type` - Type of buyer activity

## Parameters
