# 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: Check for viewing/pickup extraction**
|
||||
|
||||
9. **appearance** (String) - Condition appearance

|
||||
|
||||
## Bid History API - Fields
|
||||
|
||||
### Currently Captured ✓
|
||||
- `buyerId` (UUID) - Anonymized bidder
|
||||
- `buyerNumber` (Int) - Bidder number
|
||||
- `currentBid.cents` / `currency` - Bid amount

|
||||
|
||||
## 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

## Summary
|
||||
|
||||
**NEW fields found:** 15+ additional intelligence fields available
|
||||
**Most critical:** `followersCount` (watch count), `estimatedFullPrice`, `nextBidStepInCents`
|
||||
**Data quality impact:** Estimated 80%+ increase in intelligence value
|
||||
|
||||
These fields will significantly enhance prediction and analysis capabilities.
