Fuses the FHFA House Price Index momentum, Census ACS demographics, housing, income, tenure and vacancy, national housing context, and Fair Market Rents into one cited JSON with computed derivatives such as gross rental yield and affordability. Aggregate market tier, not a per address valuation.
$0.03Solana0calls / 30d - GET/realestate/prices
The FHFA House Price Index for a geography: the current index level plus year over year, quarter over quarter and five year growth, with momentum flags and a short history. State and metro CBSA levels are covered directly; county and ZIP resolve to the state level index. Public domain, US only.
$0.01Solana0calls / 30d - GET/realestate/rents
Rental market indicators for a geography: HUD Fair Market Rents by bedroom count when a HUD token is configured, plus the Census ACS median gross rent as context. Falls back to the ACS rent when HUD is not configured. Aggregate market tier, US only.

$0.02Solana0calls / 30d - POST/breach/password
Check whether a password has appeared in known data breaches, using k-anonymity: the password is hashed locally and only a 5-character hash prefix is sent upstream, so the plaintext is never transmitted, logged or stored.

This is which known breaches touched the domain, not whether a specific account is compromised. Breach indicators, not a guarantee.
$0.01Solana0calls / 30d - POST/breach/assess
Composite account-takeover risk score (0-100) fusing a privacy-preserving password exposure check with a domain's known breach history.

Risk indicators, not advice.
$0.01Solana0calls / 30d - GET/cve/scan
Vulnerability scan for a software package by ecosystem, name and version, or by package-URL (purl).

Trust indicators, not a gu
$0.02Solana0calls / 30d - GET/domain/typosquat
