# API Intelligence Findings

## GraphQL API - Available Fields for Intelligence

### Key Discovery: Additional Fields Available

From GraphQL schema introspection on `Lot` type:

#### **Already Captured ✓**
- `currentBidAmount` (Money) - Current bid
- `initialAmount` (Money) - Starting bid
- `nextMinimalBid` (Money) - Minimum bid
- `bidsCount` (Int) - Bid count
- `startDate` / `endDate` (TbaDate) - Timing
- `minimumBidAmountMet` (MinimumBidAmountMet) - Status
- `attributes` - Brand/model extraction
- `title`, `description`, `images`

#### **NEW - Available but NOT Captured:**

1. **followersCount** (Int) - **CRITICAL for intelligence!**
   - This is the "watch count" we thought was missing
   - Indicates bidder interest level
   - **ACTION: Add to schema and extraction**

2. **biddingStatus** (BiddingStatus) - Lot bidding state
   - More detailed than minimumBidAmountMet
   - **ACTION: Investigate enum values**

3. **estimatedFullPrice** (EstimatedFullPrice) - **Found it!**
   - Available via `LotDetails.estimatedFullPrice`
   - May contain estimated min/max values
   - **ACTION: Test extraction**

4. **nextBidStepInCents** (Long) - Exact bid increment
   - More precise than our calculated bid_increment
   - **ACTION: Replace calculated field**

5. **condition** (String) - Direct condition field
   - Cleaner than attribute extraction
   - **ACTION: Use as primary source**

6. **categoryInformation** (LotCategoryInformation) - Category data
   - Structured category info
   - **ACTION: Extract category path**

7. **location** (LotLocation) - Lot location details
   - City, country, possibly address
   - **ACTION: Add to schema**

8. **remarks** (String) - Additional notes
   - May contain pickup/viewing text
   - **ACTION: Check for viewing/pickup extraction**

9. **appearance** (String) - Condition appearance
   - Visual condition notes
   - **ACTION: Combine with condition_description**

10. **packaging** (String) - Packaging details
    - Relevant for shipping intelligence

11. **quantity** (Long) - Lot quantity
    - Important for bulk lots

12. **vat** (BigDecimal) - VAT percentage
    - For total cost calculations

13. **buyerPremiumPercentage** (BigDecimal) - Buyer premium
    - For total cost calculations

14. **videos** - Video URLs (if available)
    - **ACTION: Add video support**

15. **documents** - Document URLs (if available)
    - May contain specs/manuals

## Bid History API - Fields

### Currently Captured ✓
- `buyerId` (UUID) - Anonymized bidder
- `buyerNumber` (Int) - Bidder number
- `currentBid.cents` / `currency` - Bid amount
- `autoBid` (Boolean) - Autobid flag
- `createdAt` (Timestamp) - Bid time

### Additional Available:
- `negotiated` (Boolean) - Was bid negotiated
  - **ACTION: Add to bid_history table**

## Auction API - Not Available
- Attempted `auctionDetails` query - **does not exist**
- Auction data must be scraped from listing pages

## Priority Actions for Intelligence

### HIGH PRIORITY (Immediate):
1. ✅ Add `followersCount` field (watch count)
2. ✅ Add `estimatedFullPrice` extraction
3. ✅ Use `nextBidStepInCents` instead of calculated increment
4. ✅ Add `condition` as primary condition source
5. ✅ Add `categoryInformation` extraction
6. ✅ Add `location` details
7. ✅ Add `negotiated` to bid_history table

### MEDIUM PRIORITY:
8. Extract `remarks` for viewing/pickup text
9. Add `appearance` and `packaging` fields
10. Add `quantity` field
11. Add `vat` and `buyerPremiumPercentage` for cost calculations
12. Add `biddingStatus` enum extraction

### LOW PRIORITY:
13. Add video URL support
14. Add document URL support

## Updated Schema Requirements

### lots table - NEW columns:
```sql
ALTER TABLE lots ADD COLUMN followers_count INTEGER DEFAULT 0;
ALTER TABLE lots ADD COLUMN estimated_min_price REAL;
ALTER TABLE lots ADD COLUMN estimated_max_price REAL;
ALTER TABLE lots ADD COLUMN location_city TEXT;
ALTER TABLE lots ADD COLUMN location_country TEXT;
ALTER TABLE lots ADD COLUMN lot_condition TEXT;  -- Direct from API
ALTER TABLE lots ADD COLUMN appearance TEXT;
ALTER TABLE lots ADD COLUMN packaging TEXT;
ALTER TABLE lots ADD COLUMN quantity INTEGER DEFAULT 1;
ALTER TABLE lots ADD COLUMN vat_percentage REAL;
ALTER TABLE lots ADD COLUMN buyer_premium_percentage REAL;
ALTER TABLE lots ADD COLUMN remarks TEXT;
ALTER TABLE lots ADD COLUMN bidding_status TEXT;
ALTER TABLE lots ADD COLUMN videos_json TEXT;  -- Store as JSON array
ALTER TABLE lots ADD COLUMN documents_json TEXT;  -- Store as JSON array
```

### bid_history table - NEW column:
```sql
ALTER TABLE bid_history ADD COLUMN negotiated INTEGER DEFAULT 0;
```

## Intelligence Use Cases

### With followers_count:
- Predict lot popularity and final price
- Identify hot items early
- Calculate interest-to-bid conversion rate

### With estimated prices:
- Compare final price to estimate
- Identify bargains (final < estimate)
- Calculate auction house accuracy

### With nextBidStepInCents:
- Show exact next bid amount
- Calculate optimal bidding strategy

### With location:
- Filter by proximity
- Calculate pickup logistics

### With vat/buyer_premium:
- Calculate true total cost
- Compare all-in prices

### With condition/appearance:
- Better condition scoring
- Identify restoration projects

## Updated GraphQL Query

```graphql
query EnhancedLotQuery($lotDisplayId: String!, $locale: String!, $platform: Platform!) {
  lotDetails(displayId: $lotDisplayId, locale: $locale, platform: $platform) {
    estimatedFullPrice {

      max { cents currency }
    }
    lot {
      id
      displayId
      title
      description { text }
      currentBidAmount { cents currency }
      initialAmount { cents currency }
      nextMinimalBid { cents currency }
      nextBidStepInCents
