summary: Regional Economy & Trade Brief
description: 'Given a US state, county or metro (name, FIPS or CBSA), an industry (NAICS code or description) and a role (retailer, logistics, cfo, lender, other), reads BLS LAUS and QCEW, FRED (state employment, house prices, goods exports and imports, regional CPI), Census Building Permits and USAspending live, then computes levels, year-over-year and three-year changes, location quotient, z-scores against the national series, trend direction with a stated threshold and data freshness. Each indicator carries value, period, source URL and fetch time. A short business brief for the role is written from the computed table only; any statement with a number not in the table, or forward-looking wording, is dropped and listed. Returns INSUFFICIENT_DATA when too few series resolve, and lists what was not checked (Census ACS/CBP/trade APIs need a key). Descriptive analysis, not a forecast or financial advice.
Price: 0.75 USDC on Base (x402).'
