Grant/RFP Opportunity Radar — SAM.gov, Filtered & Ranked

Every US federal contract opportunity is legally required to post on SAM.gov — solicitations, presolicitations, sources-sought notices, the full pipeline. Gov-contracting consultants currently pay $300+/mo for third-party tools (GovWin and similar) just to get it filtered by NAICS code and alerted by deadline.

This is SAM.gov's own official free API, filtered and ranked by response deadline so you see what needs action this week versus what's still weeks out.

⚠️ Requires your own free SAM.gov API key

SAM.gov's public/unregistered quota is only 10 requests/day — too thin to share across users. Get a free key: sign in at sam.gov, open Account Details, Request Public API Key. Pass it as samGovApiKey in the input. A registered key gets 1,000 requests/day.

Input

{
  "samGovApiKey": "your-free-key",
  "searches": [{ "naicsCode": "541512", "state": "VA" }],
  "daysBack": 30
}

Each search needs a NAICS code and/or keyword; state and set-aside type are optional filters.

⚠️ Read before you act

• The API key is required for every request — there is no fallback path. SAM.gov's gateway returns a bare 404 (not 401) for a missing or invalid key, which this actor translates into an actionable error message rather than a generic HTTP failure.
• daysBack is capped at 364 days — this mirrors SAM.gov's own documented window limit for the search API.
• Urgency is calculated from the response deadline, not the posted date — a notice posted today with a deadline next week is urgent; one posted a month ago with a deadline next month is not.

FAQ

• Why do I need my own key? SAM.gov's public quota (10 req/day, unregistered) is too thin to share across every user of this actor. Your own free key gets 1,000/day.
• What if my key is wrong? You'll see "No response from SAM.gov... this usually means the API key is missing or invalid" in the problems report — SAM.gov's own gateway doesn't distinguish a bad key from a dead endpoint, so this actor spells out the likely cause.
• Can I search multiple NAICS codes at once? Yes — add multiple entries to the searches array.
