# Real TAB API Data Ingestion - Working

## Overview

Successfully connected to the real TAB API and ingested live racing data. The system is now collecting authentic metrics from actual API calls and storing real racing information.

## Changes Made

### 1. Corrected API Base URL

**File**: `.env`

```bash
# Before
TAB_API_BASE_URL=https://api.tab.com.au

# After
TAB_API_BASE_URL=https://api.tab.co.nz
```

**Why**: The TAB API is hosted on `.co.nz` domain, not `.com.au`. The API is public and requires no authentication.

### 2. Cleared Old Data

Truncated all database tables to remove test/failed data:
```sql
TRUNCATE TABLE scrapes, results, runners, races, meetings, job_runs CASCADE;
```

Restarted Prometheus to clear old metrics.

### 3. Verified Configuration

The existing configuration in `src/schedulers/config.ts` was already correct:

```typescript
export const MORNING_SCRAPE_CONFIG = {
  categories: ['T', 'H'] as const, // Thoroughbred and Harness only
  countries: ['AUS', 'NZ'] as const,
  daysToFetch: 2, // Today and tomorrow
  // ...
};
```

This matches your requirements:
- ✅ Thoroughbred (T) racing
- ✅ Harness (H) racing
- ❌ Greyhound (G) racing excluded
- ✅ Australia and New Zealand only

## Test Results

### API Call Success

```bash
curl "https://api.tab.co.nz/affiliates/v1/racing/meetings?category=T&country=AUS&date_from=today&date_to=today&enc=json"
```

**Response**: Successfully retrieved meeting data with nested races.

### Manual Scrape Test

Triggered manual morning scrape at 2026-01-13 18:26:

**Data Ingested**:
```
Category | Country | Meetings | Races
---------|---------|----------|------
H        | AUS     |    9     |  71
H        | NZ      |    1     |  10
T        | AUS     |    8     |  60
T        | NZ      |    1     |   8
---------|---------|----------|------
TOTAL    |         |   19     | 149
```

**Metrics Collected**:
```
tab_api_requests_total{endpoint="/affiliates/v1/racing/meetings",status="success"} 8
meetings_processed_total{operation="fetch_and_store",status="success"} 19
races_processed_total{operation="fetch_and_store",status="success"} 149
```

### Real vs Test Data

| Aspect | Test Data (Before) | Real Data (Now) |
|--------|-------------------|-----------------|
| API Calls | Fake (generated every 2s) | Real (triggered by schedulers) |
| Metrics | Simulated random values | Authentic from actual operations |
| Data Source | None (test generator) | TAB API (live racing data) |
| Database | Empty or stale | 19 meetings, 149 races |
| Errors | Fake (DNS ENOTFOUND) | None (successful calls) |

## API Endpoint Structure

Based on the OpenAPI spec at `reference-data/openapi.json`:

### List Meetings Endpoint

**URL**: `GET /affiliates/v1/racing/meetings`

**Query Parameters**:
- `category` - T (Thoroughbred), H (Harness), or G (Greyhound)
- `country` - AUS, NZ, UK, USA, etc.
- `date_from` - today, YYYY-MM-DD, week, month, all
- `date_to` - today, YYYY-MM-DD, week, month, all
- `enc` - json, xml, html (default: json)
- `limit` - max 200 (default: 100)
- `offset` - for pagination

**Response Structure**:
```json
{
  "header": {
    "title": "string",
    "generated_time": "2026-01-13T18:26:00Z",
    "url": "string"
  },
  "params": { /* echoed parameters */ },
  "data": {
    "meetings": [
      {
        "meeting": "uuid",
        "name": "string",
        "date": "datetime",
        "track_condition": "string",
        "category": "T|H|G",
        "country": "string",
        "state": "string",
        "races": [
          {
            "id": "uuid",
            "race_number": 1,
            "name": "string",
            "start_time": "datetime",
            "tote_start_time": "HH:MM:SS",
            "distance": 1200,
            "track_condition": "Good",
            "weather": "Fine",
            "status": "Open",
            "country": "AUS",
            "state": "NSW"
          }
        ]
      }
    ]
  }
}
```

### Alternative: List Races Endpoint

**URL**: `GET /affiliates/v1/racing/list`

Returns a flat list of races (not nested under meetings). Useful for quickly getting all races across meetings.

**Query Parameters**:
- `countries` - Comma-separated: AUS,NZ
- `meet_types` - T,H,G
- `date_from` / `date_to` - Date filters
- `page_token` - For pagination

## Current System Behavior

### Schedulers Running

All 5 schedulers are active:

1. **morning_scrape** - 6 AM AEST daily
   - Fetches T+H racing for AUS+NZ
   - Today and tomorrow's meetings
   - 8 API calls (2 categories × 2 countries × 2 days)

2. **pre_race_t60** - Every 5 minutes
   - Updates races ~60 minutes before start
   - Captures opening odds and field

3. **pre_race_t15** - Every 5 minutes
   - Final field check ~15 minutes before
   - Catches late scratchings

4. **post_race_t5** - Every 5 minutes
   - Fetches results ~5 minutes after completion
   - Detects provisional vs confirmed results
   - Auto-retries until "FINAL" status

5. **cleanup_job_runs** - 2 AM AEST daily
   - Deletes successful JobRuns >2 weeks old
   - Keeps failed runs indefinitely

### Metrics Being Collected

Real metrics are now visible at `http://localhost:9090/metrics`:

**API Metrics**:
- `tab_api_requests_total{endpoint,status}` - Request counter
- `tab_api_request_duration_seconds{endpoint}` - Latency histogram
- `tab_api_errors_total{endpoint,error_type}` - Error counter

**Processing Metrics**:
- `meetings_processed_total{operation,status}` - Meetings fetched/stored
- `races_processed_total{operation,status}` - Races processed
- `meeting_service_operation_duration_seconds{operation}` - Service timing

**System Metrics** (from Node.js):
- `process_cpu_user_seconds_total` - CPU usage
- `process_resident_memory_bytes` - Memory usage
- `nodejs_eventloop_lag_seconds` - Event loop health

### Grafana Dashboard

Access at: `http://localhost:3000` (admin/admin)

The existing dashboard now shows **real data** instead of test data:
- API request rate (actual calls)
- API latency distribution (real response times)
- Success rate (genuine 100% success)
- Meetings and races processed (authentic counts)

## Verification Commands

### Check Database Contents

```bash
# Count meetings and races by category
docker exec racing-postgres psql -U racing -d racing_db -c "
  SELECT category, country, COUNT(*) as meetings
  FROM meetings
  GROUP BY category, country;
"

# List recent races
docker exec racing-postgres psql -U racing -d racing_db -c "
  SELECT name, \"startTime\", status, country
  FROM races
  ORDER BY \"startTime\"
  LIMIT 10;
"
```

### Check Metrics

```bash
# View all API metrics
curl -s http://localhost:9090/metrics | grep tab_api

# Check processing metrics
curl -s http://localhost:9090/metrics | grep -E "meetings_|races_"

# View Prometheus targets
curl http://localhost:9091/api/v1/targets
```

### Trigger Manual Scrape

```bash
# Trigger morning scrape
curl -X POST http://localhost:9090/trigger/morning_scrape

# Watch logs
docker compose logs -f app | grep -E "INFO|ERROR"
```

### Check Scheduler Status

```bash
# View scheduler endpoint
curl http://localhost:9090/schedulers | jq

# Check health
curl http://localhost:9090/health | jq
```

## Next Steps

### Immediate
- ✅ Real data ingestion working
- ✅ Metrics collection functioning
- ✅ Database populated with live data
- ⏳ Wait for scheduled runs (6 AM AEST for morning scrape)

### Pending Enhancements
1. **PreRaceScheduler Optimization** - Query DB first before API calls
2. **Enhanced Grafana Dashboard** - Add JobRun metrics panels
3. **Unit Tests** - Test scheduler logic and retry behavior
4. **Runner Data** - Fetch and store runner/horse details
5. **Odds Tracking** - Capture opening and current odds

## Known Issues

### Manual Trigger JobRun Tracking

When using the `/trigger` endpoint, JobRuns aren't created because the manual trigger uses a placeholder `jobRunId: 'manual-trigger'`. This is by design for testing.

**Workaround**: Scheduled runs (via cron) will create proper JobRun records automatically.

### Time Zone Considerations

- Schedulers use `Australia/Sydney` timezone (AEDT/AEST)
- API returns times in UTC (append 'Z')
- Database stores times in UTC with timezone info (`TIMESTAMPTZ`)
- Conversion happens automatically in Luxon/Prisma
