How this service works
Use to find who is about to build what in the Rio Grande Valley, Texas (Hidalgo, Cameron, Starr, Willacy counties): commercial projects over $50,000 filed with the state before construction, with owner, design firm, estimated cost, square feet and dates. For suppliers, subcontractors, lenders and brokers chasing new work. Filter by city, county, since, min_cost or owner. Example: "What commercial projects were registered in Hidalgo County since Sept 1, who owns them and how big are they?"
Output
A JSON object containing matched project count, query echo, dataset metadata (cadence, coverage, as-of date), and an array of project records each with ID, name, owner, address, city, ZIP, county, type of work, scope of work, estimated cost in USD, square footage, start/end dates, status, design firm, funding type, and facility name.
Example use cases
Tracking large commercial builds in McAllen
“Show me up to 20 construction projects in McAllen, Hidalgo County filed since 2025-01-01 with an estimated cost over $250,000 — I want to see the biggest commercial activity happening there.”
Monitoring a specific developer's pipeline
“Find all construction filings in Cameron County where the owner name includes 'Valley Health' — I want to track every project they've registered.”
Scouting new builds in a border city
“What are the 15 most recent construction projects filed in Brownsville? Give me everything filed since 2024-10-01 so I can see what's being built there.”

Endpoint
GEThttps://fronterasignal.com/api/v1/projects?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, filterable construction project data specifically for the Rio Grande Valley counties of Hidalgo, Cameron, Starr, or Willacy in Texas. It is ideal for tracking regional development activity, monitoring specific owners or developers, or surfacing high-value construction opportunities by cost threshold. Prefer it over general permit databases when you need weekly-refreshed, bilingual coverage of this specific border region.
Side effects
- Invalid county enum value returns validation error
- Date format not matching YYYY-MM-DD causes query rejection
- Limit outside 1-100 range may be rejected or clamped
- No projects matching filters returns empty projects array with matched=0
- Stale data warning if weekly dataset has not been refreshed within 14 days
