Housing answers your agent can cite.
Rates, prices, permits and parcels behind one URL.
Ask where rates are, what a property last sold for, how much inventory a metro is carrying, or what a household at 80% of area median can afford — and get the answer with the release or record it came from. Your agent reads Census, HUD, ATTOM and Altos directly, so a number never depends on when a model was trained.
What it answers
Grouped by the job, not by the database. Every question shown below was run against the live gateway before it was printed here.
Where the market actually is
“What is the US homeownership rate?”
The Census Housing Vacancy Survey figure for the current quarter, with its standard error and the matching vacancy rates.
- Mortgage rates, starts, permits and completions as the releases land
- Case-Shiller metro comparisons, and a single-call market snapshot per metro
A specific property, and what it is worth
- ATTOM property detail, sales history, assessments, AVM valuations and rental AVMs
- School search around an address, and sales-trend context for the surrounding market
Supply, inventory and momentum
- Altos weekly market stats — active listings, new listings, pending sales, inventory trend
- Census building permits and housing starts by geography and period
Affordability and policy
“What is the current average 30-year fixed mortgage rate in the US?”
This week’s survey rate, with the release it came from.
- HUD fair market rents, income limits, CHAS need data and geographic crosswalks
- Local employment and income context from BLS and the ACS

Where the answers come from
Primary sources only. No scraped aggregators, and no model-written summary standing in for a record.
Census
American Community Survey, building permits, housing starts, homeownership and vacancy — the official series, by geography and period.
HUD
Fair market rents, income limits, CHAS affordability need, and the crosswalk files that map ZIPs to tracts and counties.
ATTOM
Parcel-level property detail, sales history, tax assessments, AVM and rental AVM valuations, and nearby schools.
Altos Research
Weekly local-market inventory: active and new listings, pending sales, and the inventory trend behind a market call.
Rates and macro
FRED for mortgage rates and the wider macro series; BLS for local employment and wage context.
Compound reads
Single-call market snapshots, property reports, rental analyses, affordability checks and metro demand screens that fold several of the above into one answer.

What data sources are included in Housing Intel?
Housing Intel bundles FRED (mortgage rates, housing starts, Case-Shiller), BLS (CPI shelter, construction employment), Census Bureau (building permits, ACS housing), HUD (fair market rents, income limits), ATTOM Data (property-level detail, AVM valuations, sales history), and Altos Research (weekly inventory, days on market) into a single MCP connection.
Can I get property-level valuations and rental estimates through Pipeworx?
Yes. ATTOM provides automated valuation (AVM), rental AVM with yield, full sales history, tax assessments, and school data at the address level. Altos Research adds weekly market statistics — active listings, pending sales, new listings, price reductions — at the ZIP, city, or state level. Both require their own API keys; sign up for a 30-day ATTOM trial at api.developer.attomdata.com.
How is Pipeworx Housing Intel different from a Zillow API or Redfin scrape?
Zillow's official API was retired for general use, and scraping listing sites is fragile and prohibited by their terms. Housing Intel uses primary-source institutional data: ATTOM for property records, HUD for affordability, FRED for macro indicators, BLS for labor data. The result is durable, citation-friendly data agents can rely on for analysis rather than thin display scraping.
What does the housing_signal_scan tool actually scan?
housing_signal_scan walks 46 indicators across FRED, BLS, and Census — Case-Shiller for 20 metros, metro CPI for 14 cities, NAR existing-home sales, construction employment, wage growth, and labor-market data — and flags reversals, unusual moves, acceleration, and extreme readings. One call surfaces the signals worth investigating instead of a 46-series time-series dump.
