How this service works
Pay-per-call data & tool APIs
Output
Returns a JSON object with a market decision ('below_aggregate_market_review', 'above_aggregate_market_review', or at-market), percentage deviation from the sahibindex benchmark price, liquidity signal (normal/slow), confidence level, source PDF metadata including SHA256 and page count, reference month, supported cities, and a stable ID for the benchmark run. Also includes reasoning for the decision (freshness, liquidity days, threshold, comparison values).
Example use cases
Property buyer price sanity check
“I'm looking at a 120 m² apartment in Ankara listed at 7,200,000 TRY — can you run it against the sahibindex benchmark for March 2026 to tell me if it's overpriced and by how much?”
Real estate agent listing review
“I need to set a competitive asking price for a 90 m² flat in İzmir for sale — benchmark it against the sahibindex aggregate for February 2026 and tell me if we're above or below market.”
Investment portfolio market position audit
“For a property I own in Istanbul, ID 'istanbul_prop_xyz123', 100 m² valued at 6,100,000 TRY, run the sahibindex sale benchmark for March 2026 and tell me the deviation from aggregate and whether liquidity is normal.”
Technical details
Endpoint
POSThttps://api.timzinin.com/api/sahibindex-property-market-benchmarkWhen to prefer
Use this endpoint when you need to benchmark a Turkish residential property's asking price against the official sahibindex (sahibinden.com + BETAM) aggregate market report for a specific city and month. Prefer this over generic AVM (automated valuation model) services when you specifically need sahibindex methodology, Turkish lira benchmarks, and traceable PDF source attribution for İstanbul, Ankara, or İzmir markets.
Side effects
- City not covered by sahibindex report (only Türkiye aggregate, İstanbul, Ankara, İzmir supported)
- Report month has no available sahibindex PDF — stale or future dates return errors
- Invalid or missing property price/area inputs cause validation failure
- PDF source unavailable or SHA256 mismatch causes retrieval failure
- Low confidence result when subject price deviates marginally near threshold
