How this service works
Use to check what common building materials cost on the shelf in the Rio Grande Valley (McAllen, Mission, Edinburg): 2x4 and 2x6 studs, OSB, drywall, concrete mix, CMU block, rebar, shingles, underlayment, housewrap, insulation, paint, doors, deck screws. Dated prices at big-box stores and a local yard, checked twice a week, for estimating or checking a bid. Not a quote. Example: "What does a sheet of 7/16 OSB cost in McAllen this week?"
Output
A JSON object containing an array of matching material price rows, each with item name, item_key, unit, price_usd, store type, outlet_id, city, observed date, and age_days. Also includes dataset metadata: region (Rio Grande Valley, Texas), data source, cadence (twice a week), data_through date, first_observed date, a disclaimer about staleness thresholds, and a rule clarifying that only single-unit shelf prices are included (no volume-tier pricing).
Example use cases
Contractor material cost estimate
“I'm bidding a job in Mission, TX — can you look up the current price of OSB and drywall at big-box stores in the Rio Grande Valley so I can put together my materials budget?”
Price comparison across store types
“What's the difference in rebar prices between big-box stores and local yards in McAllen right now? I want to know which type of supplier is cheaper.”
Tracking material price trends
“Can you pull the latest drywall prices from Frontera Signal for Hidalgo County and tell me how old the data is? I'm tracking whether prices have been going up.”
Technical details
Endpoint
GEThttps://fronterasignal.com/api/v1/materials?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need current, local construction material shelf prices specifically in Hidalgo or Cameron County (Rio Grande Valley), Texas — especially for common items like OSB, drywall, rebar, lumber, and concrete. It is ideal for contractors, developers, or researchers needing twice-weekly updated prices from both big-box and local yard suppliers. Prefer this over national pricing APIs when South Texas regional accuracy matters.
Side effects
- No matching rows returned if item key or store filter doesn't match any tracked product
- Stale data warning if prices are older than 14 days (weekly cadence) or 30+ days (monthly measures)
- Item not tracked: some niche building materials may not be in the dataset
- Invalid query parameter value returns empty result rather than an error
- Payment failure at x402 layer prevents access to endpoint
