Example prompt: What's the sell probability score for 245 Summer Street in Boston, MA — I want to know how motivated the owner might be to sell based on ownership aging, distress signals, and deal momentum.

## When to prefer this

Use this endpoint when you need a fast, quantified sell-likelihood score for a specific Northeast US commercial property address before committing to deeper due diligence. It is ideal for triage and deal sourcing workflows where you want to prioritize which owners to contact. Prefer this over the full 4-lens AI deal scoring endpoint when you only need a quick sell signal rather than a full investment thesis.

## Known failure modes

- Address not found in deed records — returns null or low-confidence score
- State code not in Northeast coverage area — may return out-of-scope error
- Address format not parseable — returns 400 validation error
- Insufficient historical data for the property — score returned with low confidence flag
- Payment failure via x402 — returns 402 Payment Required

## How this service works

Sell probability score 0–100% based on aging ownership, DOM, distress, deal momentum

## Output

A 0–100% sell probability score derived from a multi-factor model incorporating ownership aging (years held), days-on-market data, distress signals, and deal momentum. The response indicates how likely the current owner is to sell, helping investors prioritize outreach and deal sourcing.
