Stability Index formula
The index is a weighted average of seven inputs, each normalized to a 0-1 "goodness" score before weighting, then scaled to 0-100. It is derived, not random: two properties with the same inputs always get the same index.
| Factor | Weight | Direction | Range |
|---|---|---|---|
| Comp dispersion | 20% | Lower is better | 2–35% |
| Comp count | 15% | Higher is better | 4–30 |
| Comp distance | 15% | Lower is better | 0.1–3.5mi |
| 12-month sales velocity | 15% | Higher is better | 2–60sales |
| Price trend | 15% | Higher is better | -8–15% |
| Renovated share | 10% | Higher is better | 0–80% |
| Model drift | 10% | Lower is better | 0–12% |
Read interface
x402 pay-per-read$0.02 USDC / read
The same valuation data is available over HTTP for agents and services that would rather pay per call than read on-chain. Endpoint: GET /oracle/v1/valuation/:propertyKey
Paying requires a Stellar wallet that supports auth-entry signing. The API does not accept raw account keys.
