How this service works
ACS 2023 median real-estate taxes paid (B25103), median owner-occupied home value (B25077), and the effective rate they imply at ZIP, county, and state, with the Lincoln Institute 50-state study linked. Returns the same records as locus_property_tax_context. Use this when your client can only call paid x402 routes. Use locus_property_tax_context instead when you can call Locus free tools (REST tools/call or MCP).
Output
Returns median real-estate taxes paid, median home value, and the implied effective tax rate for the ZIP code, county, and state corresponding to the input address or coordinates, sourced from ACS 2023 data. Also includes a link to the Lincoln Institute 50-state study. This is a locality-level statistical estimate, not the specific parcel's actual tax bill.
Example use cases
Evaluating tax burden before home purchase
“I'm looking at buying a house at 1234 Maple Ave, Austin, TX 78701 — can you pull the effective property tax rate for that ZIP and county so I know if the tax burden is typical for the area?”
Validating a received tax bill
“I just got my property tax bill for my home at 88 Ocean Drive, Miami Beach, FL 33139 and it seems high — what's the median real-estate tax and effective rate for that ZIP and county so I can see if this is normal?”
Comparing tax burden across investment markets
“I'm comparing investment properties — can you get me the effective property tax rate context for 500 N Michigan Ave, Chicago, IL 60611, including the ZIP, county, and state medians from ACS data?”
Technical details
Endpoint
POSThttps://api.locus.report/api/locus-property-tax-context?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to contextualize a property tax bill or assess the typical tax burden for a US location at ZIP, county, or state level using authoritative ACS data. Prefer this over general web search when you need structured, comparable rate benchmarks. Not suitable when you need the specific assessed value or actual tax bill for an individual parcel — use a parcel-record endpoint for that.
Side effects
- Address cannot be geocoded or matched to a US jurisdiction — returns error or null coverage
- Input address is outside the United States — no data available
- ZIP or county not covered in ACS 2023 release — partial or null response
- Malformed coordinates outside valid US range — validation error
- Missing both address and coordinates — request rejected
