Data Sources

Platform	RSVP Data	Organizer Data	Data Quality
Meetup	✅ RSVP counts (always public)	Group members, profile URL	Excellent
Lu.ma	✅ Guest counts (usually public)	Host profile, event history	Excellent
Eventbrite	❌ Not available	Organizer followers, profile	Good

Input Configuration

Basic Example

{
  "queries": [
    {
      "keywords": ["tech", "startup"],
      "locations": ["San Francisco, US"],
      "dateFrom": "2026-01-01",
      "dateTo": "2026-03-01",
      "platforms": ["eventbrite", "meetup", "luma"]
    }
  ],
  "minAttendees": 20,
  "generateICS": true,
  "webhookUrl": "https://n8n.yourdomain.com/webhook/events"
}

Note on minAttendees: This filter uses rsvpCount as the metric. Only Meetup and Lu.ma provide RSVP counts, so Eventbrite events will be included regardless of this setting.

Location Fields Explained:

• city: City name, or "Online" for virtual events
• country: ISO country code (e.g., "DE", "US", "GB"), or null for online events
• latitude/longitude: Geographic coordinates (null for online events or when unavailable)

This structure makes it easy to filter events by location while clearly distinguishing online vs. physical events.

Output Formats

1. Dataset: Normalized JSON records in Apify dataset
2. ICS Calendar: Saved to Key-Value Store as calendar.ics
3. Webhook: POST to your n8n workflow with stats and first 100 events

Deduplication Strategy

Events are deduplicated using multi-factor fuzzy matching:

1. Canonical Key: Hash of (normalized title + start time UTC + normalized city)
2. Fuzzy Title Matching: Jaro-Winkler similarity ≥ 82% (configurable)
3. Time Window: Events within 90 minutes of each other (configurable)
4. Geo Distance: Events within 800 meters (configurable)

RSVP Count Availability

Platform	Availability	Field Used
Meetup	✅ Always public	rsvpCount
Lu.ma	✅ Usually public	rsvpCount (guest_count)
Eventbrite	❌ Not available	rsvpCount (always null)

Note: For Eventbrite events, consider using organizerFollowers as an alternative audience signal when available.

• Event Name: event-ingested
• Price: ~$0.01 per event (configure in Apify Console)
• No platform fees if published before March 31, 2025 (0% commission for 6 months)

Cost Examples

Scenario	Events	Estimated Cost
Small run (2 cities, 1 keyword, 30 days)	~100-300	$1-3
Medium run (5 cities, 3 keywords, 60 days)	~500-1000	$5-10
Large run (10 cities, 5 keywords, 90 days)	~2000-5000	$20-50

Platform-Specific Notes

Meetup

• Data Source: __NEXT_DATA__ JSON in page HTML
• RSVP Counts: Always publicly visible (yes_rsvp_count)
• Best For: Community events, tech meetups, networking
• Proxy: Datacenter proxy works fine

Lu.ma

• Data Source: API endpoint /discover/get-events
• Guest Counts: Usually publicly visible (guest_count)
• Best For: Creator events, workshops, online events
• Proxy: Datacenter proxy works fine

Eventbrite

• Data Source: __SERVER_DATA__ JSON in page HTML
• URL Format: /d/{country}--{city}/{keyword}/ for keyword-based discovery
• Search Strategy: Creates separate URLs for each keyword (e.g., /medtech/, /technology/)
• Attendee Counts: Rarely visible on public pages
• Organizer Followers: Often visible (use as audience signal)
• Best For: Professional conferences, large events, ticketed events
• Proxy: Datacenter proxy works fine
• Note: Eventbrite's keyword-based URLs are case-insensitive and normalize spaces to hyphens

Development & Testing

Local Testing

# Install dependencies
npm install

# Build TypeScript
npm run build

# Test with pay-per-event simulation
npm run test:ppe

# Regular dev run
npm run dev

Pay-Per-Event Testing

ACTOR_TEST_PAY_PER_EVENT=true \
ACTOR_USE_CHARGING_LOG_DATASET=true \
npm run dev

Check the charging-log dataset to see all billing events triggered.

Limitations

• LinkedIn Events: Not included (requires residential proxy + complex anti-bot handling)
• Eventbrite Attendee Counts: Rarely public on event pages
• Rate Limits: Respects platform rate limits with automatic backoff
• Geo Accuracy: Depends on platform-provided coordinates
• Historical Events: Only finds future events (past events not scraped)

Error Handling

The Actor implements robust error handling:

• 3 retries with exponential backoff per request
• Platform-level circuit breakers (fail-fast if >10% error rate)
• Graceful degradation (continues with other platforms if one fails)
• Error logging with sample HTML snapshots for debugging

Performance

Typical run times (with default concurrency):

• 2 cities, 2 keywords, 60 days, 3 platforms: 5-10 minutes
• 5 cities, 3 keywords, 60 days, 3 platforms: 10-15 minutes
• 10 cities, 5 keywords, 90 days, 3 platforms: 20-30 minutes

Memory usage: < 200 MB Concurrency: 10 concurrent requests (configurable)

Roadmap

• V1.1: Geocoding normalization (Google Maps API for missing coordinates)
• V1.2: ML-based classification (fastText/TF-Lite for smarter categorization)
• V1.3: Language filtering & i18n date parsing
• V2.0: City geo-radius search (Haversine distance queries)
