For agent builders

Give your agent public records it can cite.

Wire source-linked records across healthcare, federal procurement, sanctions and watchlists, enforcement, and corporate and securities filings into your agent. Drop the hosted Fonteum MCP server into Claude Desktop, Cursor, or any LangGraph / OpenAI / Google ADK pipeline, and keep the returned source, capture date, and limitations with each fact.

EARLY PILOT PARTNERS

Quickstart

Pick a path. Every one runs against the live demo key.

curl, TypeScript, and Python run with the fnt_DEMO_PUBLIC_V1 sample key. For account-specific limits, set FONTEUM_API_KEY after you Request API access. The MCP config is labeled for use after package publication.

curl

curl https://api.fonteum.com/v1/npi/1234567893 \
  -H "Authorization: Bearer fnt_DEMO_PUBLIC_V1" \
  -H "Accept: application/json"

No signup. The read-only demo key fnt_DEMO_PUBLIC_V1 is limited to 20 requests/minute and 100 requests/day per trusted source IP.

quickstart.ts

// No SDK yet — raw fetch. SDK ships in Q3.
const r = await fetch("https://api.fonteum.com/v1/npi/1234567893", {
  headers: { "Authorization": "Bearer fnt_DEMO_PUBLIC_V1", "Accept": "application/json" },
});
const provider = await r.json();
console.log(provider.organization_name, provider._snapshot, provider._doi);

The demo response includes its available provenance fields. Read provider._snapshot for the recorded snapshot date and provider._doi when that dataset publishes a DOI.

quickstart.py

import requests
r = requests.get(
    "https://api.fonteum.com/v1/npi/1234567893",
    headers={"Authorization": "Bearer fnt_DEMO_PUBLIC_V1", "Accept": "application/json"},
)
provider = r.json()
print(provider["organization_name"], provider["_snapshot"], provider["_doi"])

Same flat shape across every language. The underscore-prefixed keys are the provenance contract.

mcp.json

{
  "_comment": "Future stdio config for @fonteum/mcp@0.4.0; do not run it until that version is published. The bundled read-only sample key runs the documented demo path; replace it with fnt_your_api_key after issuing an account key for production limits.",
  "mcpServers": {
    "fonteum": {
      "command": "npx",
      "args": [
        "-y",

      ],
      "env": {
        "FONTEUM_API_KEY": "fnt_DEMO_PUBLIC_V1"
      }
    }
  }
}

Drop this into Claude Desktop, Cursor, Cline, or Continue. The @fonteum/mcp reads the issued key from FONTEUM_API_KEY — see the MCP server section below for the seven-tool contract.

What you get back

One flat record. A nullable fourteen-field provenance envelope.

The highlighted underscore-prefixed fields are the provenance contract: source, snapshot pin, methodology version, confidence, coverage window, persistent-identifier slot, and integrity-reference slot. Availability varies by source and response; no fact-to-signature relationship should be inferred from a separate snapshot attestation.

Public-record source areas

One product, multiple public-record domains.

Fonteum maintains an active production source registry, whose status does not establish loaded, complete, fresh, or displayable coverage. The generated catalog is a separate list of catalog entries; every published fact identifies its source and capture date.

Healthcare

Provider, facility, quality, ownership, and program-integrity records from public healthcare sources.

Federal procurement

Entity registration, award, exclusion, and ownership records for federal contractors.

Sanctions and watchlists

Dated records from U.S., EU, UK, and UN public sanctions and watchlist sources.

Enforcement and integrity

Public enforcement, exclusion, and program-integrity records with source and capture-date context.

Corporate and securities

Public corporate-register and securities-filing records where Fonteum publishes a documented source surface.

Use the source catalog and each record’s metadata to understand coverage and limitations for the specific fact you need.

MCP server (Model Context Protocol)

The hosted v1.0.0 Streamable HTTP endpoint works today. The @fonteum/mcp@0.4.0 stdio source is ready in-repo for operator publication and will work with Claude Desktop, Cursor, Cline, Continue, and other MCP-compatible clients after it is published.

Seven read-only tools

fonteum_resolve_entityResolve an NPI, UEI, or CAGE identifier to its canonical public-record entity.
fonteum_search_recordsSearch source-traced healthcare-provider records by name, specialty, or location.
fonteum_check_exclusions_and_sanctionsCheck one NPI against deployed US exclusion and debarment sources; name screening is unavailable.
fonteum_get_record_as_ofRead a federal-contractor record as it stood on a captured date.
fonteum_recheckRead the attestation-chain head or one immutable signed chain link.
fonteum_list_sourcesList the multi-vertical government-source catalog.
fonteum_dataset_infoRead methodology and provenance metadata for one deployed dataset slug.

Open ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows).
After @fonteum/mcp@0.4.0 is published, paste the mcp.json config above. Its read-only sample key runs the documented demo path; replace it with an account key for production limits.
Restart Claude Desktop.
