Steps
Obtain a SAM.gov account and generate a public API key from the user profile
Call the Get Opportunities API (documented at open.gsa.gov/api/get-opportunities-public-api) with ncode=237310 to filter to Highway, Street, and Bridge Construction
Supply required postedFrom/postedTo parameters (MM/dd/yyyy format, max one-year span per request) along with api_key
Paginate using limit/offset and parse the opportunitiesData array for solicitation number, type, and response deadline
Known gotchas
postedFrom/postedTo together cannot span more than one year per request — loop over date ranges for historical searches
Agencies sometimes miscode NAICS on postings, so ncode=237310 filtering can miss relevant paving solicitations; cross-check title/description text for 'paving'/'asphalt' as a fallback
