Time to Sell API

What Developers Build With Days-on-Market Data

Inventory Aging

Flag stock that is drifting past the median for its cohort before it turns into a markdown.

Pricing Decisions

A car sitting in the slow quartile is a pricing signal. Pair it with our Vehicle Valuation API for the number to move to.

Seller Expectations

Show sellers a realistic window instead of a guess — the median with the spread around it, not a single optimistic number.

The metric measures how long comparable listings stay live before they disappear, which also captures withdrawn and expired ads — treat it as a market-liquidity signal rather than a record of confirmed sales. The distribution is right-skewed, so report the p25–p75 spread alongside the median. Optional year, engine power, mileage and fuel filters narrow the cohort; pair with the Vehicle Valuation API to turn a slow-moving car into a price.
