How this service works
Use when you need the recent direction and level of construction inputs priced for South Texas: framing lumber, studs, OSB, drywall, rebar, copper, Gulf Coast diesel, the 30-year mortgage rate and construction PPI. Weekly, dated, ranged. Not a bid or quote.
Output
A JSON object containing an array of cost-basket rows, each with a week_id, input name (e.g. diesel_gulf_coast), numeric value, unit, direction (up/down/flat), staleness flag, age in days, data source, cadence, and a plain-language 'so_what' summary. Also includes query echo, series metadata, publisher info, schema version, and a disclaimer about staleness thresholds.
Example use cases
Weekly material cost snapshot for bid prep
“I'm putting together a construction bid for a project in McAllen — can you grab the latest Frontera Signal cost basket for Hidalgo County so I have current material and diesel prices?”
Multi-week price trend analysis
“Pull the Frontera Signal cost-basket-weekly data from 2026-W30 through 2026-W39 so I can chart how construction input costs have moved over the last couple of months in Cameron County.”
Staleness check before cost estimate submission
“Before I finalize my construction cost estimate, can you check the Frontera Signal cost basket for this week — 2026-W39 — and flag any values that are marked stale or approximated?”

Endpoint
GEThttps://fronterasignal.com/api/v1/series/cost-basket-weekly?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, time-series construction cost data specifically for Hidalgo and Cameron counties in South Texas. It is ideal for agents tracking regional construction economics, preparing bid estimates, or monitoring price direction over multiple weeks. It is not a substitute for national-level construction indices or for counties outside the Rio Grande Valley region.
Side effects
- Invalid ISO week format for 'from' or 'to' parameters returns a 400 error
- Requesting a future week range may return empty rows or stale placeholders
- Payment not processed (x402 flow failure) results in 402 Payment Required
- Very old historical weeks may have sparse or missing data points
- Network timeout if the underlying data aggregation is running
