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?
ch_run = client.actor("themineworks/companies-house-uk").call(run_input={
    "apiKey": "YOUR_COMPANIES_HOUSE_KEY",
    "query": "Example Vendor",
    "includeOfficers": True,
})
