OFAC SDN Watchlist Monitor - Exact Match

Re-screen SDN unique IDs or exact primary names you already hold against the public Treasury SDN list. Exact match only.

This Actor takes a caller-owned list of known SDN uid values and/or exact primary names, reads the public OFAC SDN CSV, and writes one structured row per query: listed or not, matched name, type and programs. Pass the previous run's snapshot back in and you get INITIAL, UNCHANGED or CHANGED when listing status or programs move.

This is not identity verification, not KYC, not AML decisioning, and not a fuzzy name-search product. It will not score “close” names, transliterations, or “is this the same person?” questions.

What this Actor does

You already have SDN unique IDs (preferred) or exact primary names copied from a prior SDN publication. You want a scheduled re-screen: still listed, programs changed, type changed — without treating the Actor as a screening engine for raw customer PII.

That is the job: exact re-screen of known SDN identifiers.

What you get

{
  "schemaVersion": 1,
  "id": "uid:36",
  "status": "ok",
  "uid": 36,
  "queryName": null,
  "listed": true,
  "matchedName": "CASTRO RUZ Fidel",
  "sdnType": "Individual",
  "programs": ["CUBA"],
  "publishDate": null,
  "changeType": "INITIAL",
  "changedFields": [],
  "checkedAt": "2026-09-06T12:00:00.000Z",
  "sourceUrl": "https://www.treasury.gov/ofac/downloads/sdn.xml",
  "error": null
}

Uid 36 / the historical Castro primary name is a public SDN example, not a customer and not an endorsement. Prefer uid in production. Name match is exact against the SDN primary-name field after punctuation is stripped.

sourceUrl stays on the public Treasury path. The Actor follows official HTTPS redirects to retrieve the list; it does not persist signed object URLs.

---

Main use cases

• Known-uid re-screen. Nightly check that SDN entries you already recorded are still present.
• Program-code movement. programs is a compared field.
• Exact-name confirmation. Only when you copied the SDN primary name exactly.
• Workflow packaging. n8n / MCP / backend job around a list you already maintain.

Do not send raw customer names, emails, or “does this person match the list?” jobs. Use a dedicated screening product for that.

Quick start

{
  "entities": [{ "uid": 36 }],
  "maxItems": 1
}

Run it, open the dataset, and save NEXT_SNAPSHOT from the default key-value store.

---

Repeat workflow

1. Keep one entity watchlist per control process (1–50 objects). Prefer uid.
2. Start a bounded run. Schedule it yourself if you need a cadence.
3. Save NEXT_SNAPSHOT in your private workflow state.
4. On the next run pass it as previousSnapshot and set onlyChanges: true.
5. Route listed flips and programs changes for human review.

---

Input

Field	Type	Default	What it does
entities	array	—	1–50 objects with uid (positive integer) and/or name (2–200 chars). Prefer uid.
maxItems	integer	50	1–50. Must cover all unique entities.
onlyChanges	boolean	false	Suppress unchanged successful records without charging them.
previousSnapshot	object	—	Prior NEXT_SNAPSHOT with kind: "ofac".

Name match is exact after uppercasing and stripping punctuation. "CASTRO RUZ, Fidel" and "CASTRO RUZ Fidel" match each other. "FIDEL CASTRO" does not.

---

Pricing

Event	Price	When it happens
Successful watchlist result	$0.004	One successful entity check written to the dataset
Actor start	none	No custom start fee

You are not charged for: failed downloads, parse failures, retries, duplicate entities, invalid input, or unchanged records suppressed by onlyChanges.

The public SDN CSV is several megabytes. One run still bills per successful entity, not per downloaded byte. A 10-uid re-screen is $0.04 in event charges when all ten succeed.

How this compares

This Actor is not priced as the cheapest OFAC name-search dump. Search-oriented Store cards (2026-09-06) sit around $0.001–$0.01 per row and imply fuzzy or bulk name lookup. Use those if you need search. Use this Actor if you need exact uid/name re-screen with isolated snapshots.

JavaScript

import { ApifyClient } from 'apify-client';

Python

from apify_client import ApifyClient
import os

client = ApifyClient(os.environ["APIFY_TOKEN"])
run = client.actor("technicaldost/ofac-sdn-entity-watchlist-monitor").call(run_input={
    "entities": [{"uid": 36}],
    "maxItems": 1,
})
for row in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(row["uid"], row["listed"], row["programs"], row["changeType"])

n8n / MCP. Server-side only. Do not send customer PII through a public agent chat.

Limitations

• Exact uid or exact normalized primary name / alias only. No fuzzy match, no phonetics, no transliteration, no “same person” scoring.
• Not a substitute for a regulated screening vendor, legal advice, or an OFAC compliance program.
• SDN CSV/XML availability and size govern run time. Allow up to a few minutes on a cold download.
• publishDate is present when the XML parser is used; the CSV path may leave it null.
• At most 1,000 snapshot records are retained.
