    list_endpointsList every paid Frontera Signal endpoint before you spend anything. Covers Rio Grande Valley, Texas construction data: permits, building-input prices, housing supply, labor, commercial projects filed with the state, company track records, filed cost per square foot, material shelf prices and the weekly briefing. Each entry has the price per call in USDC, what the call returns, an example question, its parameters with valid values and a free sample URL. Free.
    get_sampleGet a real answer from one paid endpoint for free, exactly as a paid call returns it, so you can check the fields, dates and coverage before you pay. Pass the endpoint key from list_endpoints, such as snapshot, projects or series-permits-weekly.
    how_to_payGet the exact URL to call for a paid answer, with its price, network and asset. Pass the endpoint key and the query parameters you plan to send; they go through the same free check the API runs before payment, so a query that would be refused or come back empty shows up here. This tool never calls the paid endpoint and never pays. Payment is x402: no account or API key, USDC on Base.
    get_free_seriesGet the latest 4 weeks of a weekly Rio Grande Valley series for free: permits-weekly (building permits by city), cost-basket-weekly (building-input prices), absorption (housing supply), labor-ranges (labor and financing conditions) or calls (graded forecasts). Each row carries its week, as_of date and status. The full history is a paid endpoint; how_to_pay with series-<name> gives its URL and price.
