Pricing (Pay-Per-Event)

Event	Description	Price
listing_aggregated	Per unique property aggregated	$0.10

Example costs:

• 50 listings: 50 x $0.10 = $5.00
• 200 listings: 200 x $0.10 = $20.00
• 500 listings: 500 x $0.10 = $50.00
• Demo mode: $0.00

Why This Pricing?

The aggregator runs 3 separate scrapers (Zillow, Redfin, Realtor) and performs deduplication and enrichment. The $0.10 per unique property includes:

• Running 3 platform scrapers
• Deduplication (typically 40-60% overlap = savings)
• Cross-platform data enrichment
• Price variance analysis

Typical savings: 30-50% vs running platforms separately!

FAQ

Q: How does deduplication work?

A: The aggregator normalizes addresses across platforms and matches properties. When duplicates are found, it merges data or keeps the preferred source based on your deduplicationStrategy.

Q: Why might prices differ across platforms?

A: Listing agents may update prices at different times. Price variance analysis helps identify these discrepancies - useful for negotiations.

Q: What's the typical overlap between platforms?

A: Typically 40-60% of listings appear on multiple platforms. The aggregator saves you from processing duplicates.

Q: Can I search multiple cities?

A: Currently one location per run. Schedule multiple runs for different cities or use webhooks to process in sequence.

Q: How current is the data?

A: Data is scraped in real-time from each platform. For time-sensitive searches, run the actor on-demand.
