Frontera Signal
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?"
