[Aug 20, 2025] OFAC Batch Search

You can now run OFAC checks in batch via API, allowing high-volume sanctions workflows with a single request.

Submit a CSV for batch OFAC search, no larger than 5MB, following the sample template in the API reference.

Once run, Baselayer will return a quick summary of metrics associated with the batch search, and you can also use GET/ofac/searches/batches/{batch_id}/download to retrieve the resulting OFAC batch file in jsonl format, including the details of each check.

Contact your Baselayer representative for further details.
