How this service works
Look up a Harris County property by its HCAD account number.
Output
Returns a JSON object with the property owner name, HCAD account number (geo_id), valuation breakdown (land, market, assessed, appraised, improvement values and homestead cap savings), full address details (street, city, zip), physical property characteristics (land sqft/acres, year built, improvement sqft, price per sqft), tax year of the data, and exemption flags (homestead, over-65, disabled person, disabled veteran) plus the legal description.
Example use cases
Verify ownership before real estate offer
“I'm about to make an offer on a property in Harris County and I have the HCAD account number — can you pull up the owner name, full address, and current appraised value so I can double-check everything before we proceed?”
Check senior tax exemptions on property
“My client is a retired homeowner in Harris County with HCAD account 1234560000010 — can you look up whether they have an over-65 or homestead exemption on file, and what their assessed value looks like this tax year?”
Enrich property data for investment pipeline
“I have a list of HCAD account numbers for Harris County parcels I'm evaluating — can you pull the valuation breakdown, improvement square footage, year built, and price per sqft for each one so I can run my investment analysis?”

Endpoint
GEThttps://x402datasource.com/api/v1/property/tx/harris/:propertyIdWhen to prefer
Use this endpoint when you have a specific HCAD account number and need structured property data for a Harris County, TX parcel. Prefer this over the address-search sibling endpoint when the HCAD ID is already known, as it is a direct and unambiguous lookup. Choose this for automating property research, due diligence, or data enrichment pipelines involving Harris County real estate.
Side effects

- Property exists but has no valuation data yet (nulls in values/address/property fields, as shown in example)
- Malformed propertyId format causes a 4xx error
- Payment failure or insufficient USDC balance results in 402 Payment Required
- Rate limiting or service unavailability returns 5xx error
