The Nexus API

Programmatic, source-linked access to The Nexus — the same primary-source intelligence that powers the site. Built for AI assistants, agents, researchers, and journalists. Every response carries citations and an attribution line.

EndpointWhat it returns
GET /api/v1/record/{entity}Cross-source public-record footprint (courts, SEC, OFAC, FEC, lobbying, DOJ, FDA…) with document links + a connection teaser.
POST /api/v1/factcheckA qualified verdict + rationale + linked citations for a claim. Cached verdicts are instant & free.
GET /api/v1/searchFull-text search across the article corpus (last 30 days on the free tier).
GET /api/v1/trackers/{name}/latestLatest weekly synthesis from China Watch, Underground, Graft, or Grift.

Free tier: unlimited record / search / tracker calls and unlimited cached fact-checks; 3 new fact-checks per 24h. Attribution required. Higher volume + entity-graph depth are on the paid tier.

Plans & API limits

Your API key automatically follows your Nexus account tier. To raise your limits, subscribe on the Pro page using the same email as your API key, your key levels up on its next call, with nothing to reconfigure.

PlanPriceSearch archiveNew fact-checks / day
Free$030 days3
Pro$4.99/mo90 days10
Pro+$9.99/mofull archive25
Cortex$59.99/mofull archive100

Cached fact-checks are always free and unlimited on every plan. Paid tiers also unlock the tier-gated government-record sources, and deeper entity-graph connections come with the higher tiers. Use the same email for your key and your subscription, or the API treats the key as Free.

Use it in your AI client (MCP)

The Nexus ships an official Model Context Protocol server, so Claude and other agents call these tools directly. Get a key below, then add this to your MCP client config (Claude Desktop, Claude Code, etc.):

{
  "mcpServers": {
    "nexus": {
      "command": "npx",
      "args": ["-y", "@thenexusintel/mcp"],
      "env": { "NEXUS_API_KEY": "nxs_live_your_key_here" }
    }
  }
}

Source + docs: github.com/TheNexusIntel/nexus-mcp. Tools: nexus_record_lookup, nexus_factcheck, nexus_search, nexus_tracker. Your key inherits your account tier, so a Pro or Cortex subscription lifts the same caps it does on the site.

We verify your email before issuing a key. No spam — just your key and occasional API notices.
