How this service works
Returns the same Realtor.com-on-FRED listing series and ACS home value and rent as the free route, for agents comparing a county and ZIP. Returns the same records as locus_market_context. Use this when your client can only call paid x402 routes. Use locus_market_context instead when you can call Locus free tools (REST tools/call or MCP).
Output
Returns a JSON object with county- and ZIP-level housing market data: median listing price, active listing count, and median days on market (each with year-over-year percentage change from Realtor.com/FRED monthly series), plus ACS-sourced median home value and gross rent. Data reflects recent monthly snapshots and is intended as market context, not a property valuation or ranking.
Example use cases
Home buyer market research
“I'm thinking about buying a home in the 90210 ZIP code area — can you pull the current median listing price, active inventory, and days on market there, along with year-over-year trends?”
Rental investor due diligence
“I'm evaluating a rental property at 555 Oak Avenue, Austin, TX. Can you give me the local housing market context — median listing price, how fast homes are selling, and typical gross rent in that area?”
Real estate agent listing prep
“I need a quick market snapshot for the county around 1200 Maple Street, Charlotte, NC — median listing price, active listings, days on market, and any year-over-year changes so I can set client expectations.”
Technical details
Endpoint
POSThttps://api.locus.report/api/locus-market-context?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, nationally-consistent housing market context (listing prices, inventory, days on market, rent levels) for any US address or coordinate — especially for buyer/seller research, loan underwriting context, or investor due diligence. Prefer this over manual FRED queries or paid MLS APIs when a free, geocoded, one-call market snapshot is sufficient and a formal appraisal or valuation is not required.
Side effects
- Address not geocodable — returns error if address cannot be resolved to a county/ZIP
- No FRED/Realtor.com data available for the county or ZIP — may return partial or null fields for less-populated areas
- Invalid coordinates (out of range) — validation error from schema constraints
- Missing both address and coordinates — request rejected due to insufficient location input
- Non-US address — endpoint covers only US geographies, international inputs will fail or return no data
