How this service works
Use when you have a Hidalgo County, Texas street address and need its parcel record before an offer, a loan or a site visit: parcel id, property class, acres, year built, building size, last deed, values, taxing units and the owner if it is a company or public body (people are withheld). /api/v1/parcel/match checks for free first; a miss is a 404 and is not charged. Example: "What is the parcel id, building size and market value of 800 S 10th St, McAllen?"
Output
A JSON object containing matched parcel records for the queried address, including owner name, situs address, parcel ID, land acres, building square footage, year built, property class, assessed/market/land/improvement values, deed type, last deed date, legal description, exemptions, taxing units, flood zone status with meaning, geocoordinates (lat/lon), data freshness fields (as_of, age_days, cadence), and publisher metadata.
Example use cases
Commercial property due diligence
“I'm evaluating a building at 1400 N 10th St in McAllen — can you pull the county parcel record and tell me the owner, market value, year built, and square footage?”
Flood risk check before purchase
“We're considering buying a lot at 500 W Expressway 83 in Mission, Texas — can you check the Hidalgo County parcel data and tell me if it's in a flood zone?”
Ownership verification for a site
“Who owns the property at 1200 E Trenton Rd in Edinburg? I need the owner name, deed type, and last deed date from the county records.”
Technical details
Endpoint
GEThttps://fronterasignal.com/api/v1/parcel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative county appraisal district parcel data for a specific street address in Hidalgo County, Texas (McAllen, Edinburg, Mission, Pharr, Weslaco, etc.). It is ideal for real estate due diligence, ownership lookups, valuation research, or flood risk checks in the Rio Grande Valley area. Prefer this over generic property data APIs when you specifically need Texas county appraisal records with flood zone context and construction-research-grade freshness.
Side effects
- Address not found in Hidalgo County parcel records — returns no parcels or empty match
- City outside Hidalgo County supplied — returns a 400 error (free, not charged)
- Address is ambiguous or lacks a house number — may return zero or multiple parcels
- Flood zone returned as null if Hidalgo County has no digital FIRM for the parcel location
- Stale data if county records haven't been updated recently (age_days may be high)
- Suite or unit number causes no additional filtering — ignored by design
