## Pricing

from $5.00 / 1,000 fuzzy screening matches

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## 🛡️ US Consolidated Screening List — Fuzzy Match & Delta Monitor

Screen counterparties and monitor restricted-party changes across the official U.S. Consolidated Screening List (CSL). One run covers active export and sanctions records consolidated by the Departments of Commerce, State, and Treasury — not only the OFAC SDN list.

### 🇺🇸 Broader than an OFAC-only exporter

The official CSL combines records from sources including:

- OFAC SDN and non-SDN sanctions lists;
- BIS Entity List, Denied Persons List, Unverified List, and Military End User List;
- State Department debarred and nonproliferation lists;
- additional federal export-control and restricted-party sources represented in the CSL.

### 🔎 Two workflows in one Actor

#### Name screening

Submit people, organizations, vessels, or company names. The Actor compares each input with official primary names and aliases using deterministic normalized similarity and returns the best matches above your threshold.

Each result includes the input name, matched primary name or alias, match location, score, source list, programs, countries, addresses, identifiers, remarks, and official reference URLs.

#### Snapshot and delta monitoring

Leave `screeningNames` empty to filter or export active CSL entries. Every entry receives a stable `entityKey` and SHA-256 `fingerprint`. Feed the prior run's key/fingerprint map back through `previousFingerprints` and enable `deltaOnly` to return only new or changed records.

### ⚙️ Filters and output

- country or ISO code;
- source list;
- sanctions program;
- entity type;
- free-text search across names, aliases, programs, source, and remarks;
- optional aliases, addresses, and official identifiers;
- strict result and charge limits.

The source metadata includes the official download URL, `Last-Modified`, ETag, source-list URLs, and collection timestamp for reproducible monitoring.

### 🚀 Common uses

- vendor, customer, payment, and counterparty screening workflows;
- export-control and trade-compliance research;
- procurement watchlists and scheduled list-change alerts;
- compliance data warehouses, dashboards, webhooks, n8n, Make, and AI agents.

### Example screening input

```json
{
  "screeningNames": ["Bank of Kunlun", "Example Trading Company"],
  "minimumMatchScore": 80,
  "countries": ["CN"],
  "maxItems": 100
}
```

### Result-based billing

Snapshot/export rows and fuzzy screening matches use separate events. Filters and delta comparison run before dataset writes, so omitted and unchanged entries do not create result charges.

### 📥 Complete input reference

| Field | Type | Default | Purpose |
|---|---|---:|---|
| `screeningNames` | array | `["Bank of Kunlun"]` | People, companies, vessels or organizations to fuzzy-match against primary names and aliases. Leave empty for export/monitor mode. |
| `minimumMatchScore` | integer | `75` | Deterministic normalized bigram similarity threshold from 0 to 100. |
| `query` | string | `""` | Optional contains-filter across names, aliases, programs, source and remarks. |
| `countries` | array | `[]` | Country names or ISO codes found in official addresses. |
| `sources` | array | `[]` | Filter list names such as Entity List, SDN, Denied Persons, Unverified or MEU. |
| `programs` | array | `[]` | Filter OFAC or other program tags. |
| `entityTypes` | array | `[]` | Filter types such as Entity, Individual, Vessel or Aircraft. |
| `maxItems` | integer | `1000` | Strict cap across matches or exported entries. |
| `deltaOnly` | boolean | `false` | Compare current fingerprints with the supplied previous fingerprint map and omit unchanged records. |
| `previousFingerprints` | object | `{}` | Optional map of entityKey to fingerprint from a previous run for deterministic change detection. |
| `includeAliases` | boolean | `true` | Attach official alternate names to each result. |
| `includeAddresses` | boolean | `true` | Attach official structured addresses and countries. |
| `includeIdentifiers` | boolean | `true` | Attach passports, national IDs, SWIFT/BIC and other published identifiers. |
