Search active SAM.gov contract opportunities by keyword and NAICS code and retrieve full solicitation details

Steps

1. Register a free SAM.gov account and generate a public API key from the account settings page
2. Send GET https://api.sam.gov/opportunities/v2/search with query params: api_key, keyword, naicsCode, postedFrom, postedTo, limit (max 1000), and ptype (e.g. 'o' for solicitation, 'a' for award)
3. Paginate through results using the offset parameter; each page returns a _links object and totalRecords count
4. Extract the noticeId from each result and send GET https://api.sam.gov/opportunities/v2/search?noticeid={id} to retrieve the full opportunity record including contacts, attachments, and place of performance
5. Fetch linked attachment files by following the resourceLinks URLs returned in the full opportunity response
6. Cache results with postedFrom/postedTo timestamps and poll daily near the 1000-request daily rate limit to capture new postings
