moov-io/watchman

Moov's mission is to give developers an easy way to create and integrate bank processing into their own software products. Our open source projects are each focused on solving a single responsibility in financial services and designed around performance, scalability, and ease of use.

Moov Watchman offers download, parse, and search functions over numerous trade sanction lists from the United States, agencies, and nonprofits for complying with regional laws. Also included is a web UI and an async webhook notification service to initiate processes on remote systems.

Lists included in search are:

• US Treasury - Office of Foreign Assets Control

Project status

Moov Watchman is actively used in multiple production environments. Please star the project if you are interested in its progress. If you have layers above Watchman to simplify tasks, perform business operations, or found bugs we would appreciate an issue or pull request. Thanks!

Usage

The Watchman project implements an HTTP server and Go library for searching, parsing, and downloading lists. Below, you can find a detailed list of features offered by Watchman:

• Download OFAC, US/UK/EU CSL, BIS Denied Persons List (DPL), and various other data sources on startup
  • Admin endpoint to manually refresh OFAC and DPL data
• Index data for searches
• Library for OFAC and BIS DPL data to download and parse their custom files

Docker

We publish a public Docker image moov/watchman from Docker Hub or use this repository. No configuration is required to serve on :8084 and metrics at :9094/metrics in Prometheus format. We also have Docker images for OpenShift published as quay.io/moov/watchman. Lastly, we offer a moov/watchman:static Docker image with files from 2019. This image can be useful for faster local testing or consistent results.

Pull & start the Docker image:

docker pull moov/watchman:latest
docker run -p 8084:8084 -p 9094:9094 moov/watchman:latest

Get information about a company using their entity ID:

curl "localhost:8084/ofac/companies/13374"

{
   "id":"13374",
   "sdn":{
      "entityID":"13374",

Google Cloud Run

To get started in a hosted environment you can deploy this project to the Google Cloud Platform.

From your Google Cloud dashboard create a new project and call it:

moov-watchman-demo

Enable the Container Registry API for your project and associate a billing account if needed. Then, open the Cloud Shell terminal and run the following Docker commands, substituting your unique project ID:

docker pull moov/watchman
docker tag moov/watchman gcr.io/<PROJECT-ID>/watchman
docker push gcr.io/<PROJECT-ID>/watchman

Deploy the container to Cloud Run:

gcloud run deploy --image gcr.io/<PROJECT-ID>/watchman --port 8084

Select your target platform to 1, service name to watchman, and region to the one closest to you (enable Google API service if a prompt appears). Upon a successful build you will be given a URL where the API has been deployed:

https://YOUR-WATCHMAN-APP-URL.a.run.app

Now you can ping the server:

curl https://YOUR-WATCHMAN-APP-URL.a.run.app/ping

You should get this response:

Downloads

Moov Watchman supports sending a webhook (POST HTTP Request) when the underlying data is refreshed. The body will be the count of entities indexed for each list. The body will be in JSON format and the same schema as the manual data refresh endpoint.

Watching a specific customer or company by ID

Moov Watchman supports sending a webhook periodically when a specific Company or Customer is to be watched. This is designed to update another system about an OFAC entry's sanction status.

Watching a customer or company name

Moov Watchman supports sending a webhook periodically with a free-form name of a Company or Customer. This allows external applications to be notified when an entity matching that name is added to the OFAC list. The match percentage will be included in the JSON payload.

Prometheus metrics

• http_response_duration_seconds: A histogram of HTTP response timings.
• last_data_refresh_success: Unix timestamp of when data was last refreshed successfully.
• last_data_refresh_count: Count of records for a given sanction or entity list.
• match_percentages A histogram which holds the match percentages with a label (type) of searches.
  • type: Can be address, q, remarksID, name, altName

Data persistence

By design, Watchman does not persist (save) any data about the search queries or actions created. The only storage occurs in memory of the process and upon restart Watchman will have no files or data saved. Also, no in-memory encryption of the data is performed.

Go library

This project uses Go Modules and Go v1.18 or newer. See Golang's install instructions for help setting up Go. You can download the source code and we offer tagged and released versions as well. We highly recommend you use a tagged release for production.

$ git@github.com:moov-io/watchman.git

# Pull down into the Go Module cache
$ go get -u github.com/moov-io/watchman

$ go doc github.com/moov-io/watchman/client Search

In-browser Watchman search

Using our in-browser utility, you can instantly perform advanced Watchman searches. Simply fill search fields and generate a detailed report that includes match percentage, alternative names, effective/expiration dates, IDs, addresses, and other useful information. This tool is particularly useful for completing quick searches with the aid of a intuitive interface.

Reporting blocks to OFAC

OFAC requires annual reports of blocked entities and offers guidance for this report. Section 31 C.F.R. § 501.603(b)(2) requires this annual report.

Releasing

To make a release of ach simply open a pull request with CHANGELOG.md and version.go updated with the next version number and details. You'll also need to push the tag (i.e. git push origin v1.0.0) to origin in order for CI to make the release.

Testing

We maintain a comprehensive suite of unit tests and recommend table-driven testing when a particular function warrants several very similar test cases. To run all test files in the current directory, use go test. Current overall coverage can be found on Codecov.
