Deduplication Strategies
---
How Deduplication Works
1. Address Normalization
All addresses are converted to USPS standard format:
123 Main Street, Apt 4→123 MAIN ST APT 4456 Oak Avenue #2B→456 OAK AVE #2B789 N. First Blvd→789 N FIRST BLVD
2. Matching
Properties with identical normalized addresses are grouped together.
3. Merging
Based on your strategy, data is merged:
- Price: From primary source or lowest/highest
- Zestimate: Always from Zillow (only they have it)
- Photos: Combined from all sources
- Features: Union of all features
- Agent: From most complete source
4. Variance Detection
Price differences across platforms are calculated and flagged.

Pricing
Why More Than Single-Platform Scrapers?
The aggregator runs 3 separate scrapers (Zillow, Redfin, Realtor) and then performs deduplication and enrichment. The $0.10 per unique property includes:
- Running 3 platform scrapers ($0.05 × 3 = $0.15 potential)
- Deduplication (often 40-60% overlap = savings)
- Cross-platform enrichment
- Price variance analysis

FAQ
How long does it take?
Typically 3-5 minutes depending on result count. Each platform is scraped in parallel.
What if one platform fails?
The aggregator will continue with successful platforms. You'll see which platforms returned data in the output.
Can I run just 2 platforms?
Yes! Use the platforms array to specify which ones.
How accurate is the deduplication?
Very accurate. Address normalization handles 99%+ of cases. Edge cases (typos, new construction) may occasionally slip through.
Do I need API keys for each platform?
No! All platform scrapers use web scraping. No API keys required.
