Federal Contracts, Campaign Finance & UK Company Records as Structured JSON (No Login)

Three official government registers, three plain-JSON APIs, no login and no browser required for any of them: SAM.gov federal contract opportunities, FEC campaign finance, and UK Companies House. Each is useful on its own. Run together, they answer a due-diligence question none of them can answer alone: who is this counterparty, who runs it, who funds them politically, and do they have a UK footprint worth checking separately?

SAM.gov: what’s actually up for bid

The SAM.gov actor pulls live federal contract opportunities, solicitations, presolicitations, sources-sought notices, and awards, filtered by keyword, NAICS code, agency, and set-aside type (SBA, 8(a), WOSB, HUBZone, SDVOSB).

{
  "notice_id": "a1b2c3d4e5f6...",
  "title": "Enterprise Software Licensing and Support",
  "full_parent_path_name": "DEPT OF DEFENSE.DEPT OF THE ARMY.ARMY CONTRACTING COMMAND",
  "notice_type": "Solicitation",
  "naics_code": "541511",
  "set_aside": "SBA",
  "posted_date": "2026-07-15 10:04:00-04:00",
  "response_deadline": "2026-08-14T17:00:00-04:00"
}

For a capture team, the useful move is running this on a schedule against your NAICS codes and set-aside categories, so new opportunities land in your pipeline instead of requiring a daily manual search on SAM.gov itself.

FEC: who funds them, and who they’re connected to

The FEC actor has three modes: candidates, committees, and itemized Schedule A contributions, over the official OpenFEC API.

{
  "_mode": "contribution",
  "contributor_name": "SMITH, JANE",
  "contributor_employer": "SELF",
  "contributor_occupation": "ATTORNEY",
  "amount": 250.0,
  "date": "2024-03-11"
}

The cross-reference that matters for GovCon: officers and executives of a company bidding on federal work are individuals, and individuals show up in FEC’s contributor data by name and employer. A quick committee search plus an itemized contribution pull turns “who runs this company” into “who runs this company, and what’s their political footprint”, relevant for both opposition research and internal conflict-of-interest checks before a teaming agreement.

Companies House: the UK half of the picture

The Companies House actor covers the UK equivalent: company status, incorporation date, registered office, SIC codes, and (optionally) the full officer roster, straight from the official UK register.

{
  "company_name": "EXAMPLE UK LIMITED",
  "company_status": "active",
  "sic_codes": ["62012"],
  "has_insolvency_history": false,
  "officers": [
    { "name": "SMITH, John", "officer_role": "director", "appointed_on": "2018-01-01" }
  ]
}

Any US contractor with a UK subsidiary, joint venture, or acquisition target has a Companies House footprint worth checking independently of whatever the US-side paperwork says. Insolvency and liquidation flags in particular are the kind of thing that doesn’t always surface in a US-only search.

Putting the three together

A realistic due-diligence pass on a new counterparty:

1. SAM.gov: confirm they’re actually registered and bidding on relevant work, not just claiming to be a federal contractor.
2. FEC: search their known executives by name in candidates/committees mode; pull itemized contributions if a match turns up.
3. Companies House: if they mention a UK entity anywhere (subsidiary, holding company, JV partner), verify it independently rather than taking the US-side filing at face value.

None of these three steps is novel research: every GovCon compliance team and political journalist already does some version of it by hand. What changes is the cost: three manual searches become three API calls, each billed only for results actually delivered.

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")

# Step 1 - is this vendor an active federal contractor?
sam_run = client.actor("themineworks/sam-gov-contracts").call(run_input={
    "apiKey": "YOUR_SAM_GOV_KEY",
    "organizationName": "DEPARTMENT OF DEFENSE",
    "keyword": "example vendor name",

# Step 2 - do their known officers show up as political donors?
fec_run = client.actor("themineworks/fec-campaign-finance").call(run_input={
    "mode": "candidates",
    "query": "Smith John",
})

# Step 3 - do they have a UK footprint worth checking separately?
