By October 23, 2025, all CME DataMine customers need to switch their dataset delivery mechanisms to a new platform to continue data access. Clients receiving the data from the File Browser/UI, API, SFTP, and S3 will be required to make updates, as described in this topic, to continue receiving their data.

File Download REST API

Clients may continue to download files over the CME DataMine REST API using existing CME DataMine Basic Auth API ID. The criteria will remain the same, along with the data contents. The main change to the file download API will be the URL and Endpoints changing to the following:

New Endpoint

• CME DataMine URL: https://datamine.new.cmegroup.com/cme/api/v2/download

Examples

• https://datamine.new.cmegroup.com/cme/api/v2/download?fid=20240923-SOFRT_TermRate_Fixings_0_CSV

• https://datamine.new.cmegroup.com/cme/api/v2/download?fid=20240919-LVSTOCK_BOX_BEEF_9_0

Endpoints No Longer Supported

• Concat API: https://data-api.datamine.cmegroup.com/cme/api/v1/concat 

• Batch Download: https://datamine.cmegroup.com/cme/api/v1/batchdownload?dataset=eod&yyyymmdd=20150130&period=f

Newly released functionality on the DataMine V2 endpoint is designed to mimic the user experience and data delivery of the V1 Batch endpoint. This new V2 API functionality delivers a merged CSV file containing daily End-of-Day (EOD) files.

How it Works and File Availability
Similar to the V1 Batch endpoint, this process generates three distinct files daily. Retrieving each file requires a separate API call to the V2 endpoint.
To ensure the complete dataset is compiled, the merged files may be available up to 15 minutes past their typical target times.
Files will typically be available at the following times (all times are Central Time - CT):

• E (Early): 5:45 PM CT

• P (Preliminary): 9:45 PM CT

• F (Final): 9:45 AM CT (on the next trade date)

Sample API Calls
Detailed sample API calls for this new V2 endpoint are available in a reference file.

These samples are tailored for two different subscription types:

• Single Exchange Licenses (e.g., NYMEX only)

• All CME Group Exchange Subscriptions

Please use the API call that corresponds to your current license type.

File Download API Criteria

S3 Transfer

S3 will continue to be a supported delivery destination and requires slight authorization modifications to continue using this service.

1. From the new DataMine, navigate to Settings > Data Delivery Destinations > Add Delivery Destination to set up a new delivery location.

   Open

   

2. Input the bucket name, optional subfolder name, and optional nickname for the destination. The bucket region must continue to be in AWS US East
   
   

   Open

   

3. Once saved, paste the below policy into the S3 Bucket Policy section of the AWS account to start receiving files.
   Test the configuration by selecting Test Connection to ensure the details are input correctly. Please update the {bucketName} and/or update "*" or {subPath} to reflect the target AWS bucket.

   S3 Policy

   { "Version": "2012-10-17", "Statement": [ { "Sid": "AllowForeignS3Access", "Effect": "Allow", "Principal": { "AWS": [ "arn:aws:iam::905418243502:role/venus-cmeprod-airflow-ecs-AirflowTaskRoleWithUserSe-VzZmh3EcAysc", "arn:aws:iam::905418243502:role/dhx-managed-s3-access-role-cmeprod" ] }, "Action": [ "s3:ListBucket", "s3:GetBucketLocation", "s3:PutObject" ], "Resource": [ "arn:aws:s3:::{bucket_name}/*", "arn:aws:s3:::{bucket_name}" ] } ] }
   Open

   
   Open

   

4.  Paste and save the above statement into your bucket policy and save the changes. Set up to transfer data is enabled.

SFTP

SFTP will continue being a supported delivery destination. Authentication can continue to either use Normal Login (CME API ID + CME API Password) or a Key File. The file format remains the same, but the folder organization and paths have some modifications.

Folder structure example:

/Data Category/Dataset/Year/Month/Day/Files

Directory path example:

/TERM_SOFR/TERM_SOFR_DAILY/2025/01/23/SOFRT_TermRate_Fixings_20250123.CSV”

To use the new service, please follow the below prerequisites:

1. Log in to the new CME DataMine site.

2. If normal logon, proceed to testing the SFTP site authentication. If using Key File, follow steps a and b below:

   1. Generate a SFTP public-private key pair using a key pair generator.

   2. Provide the public key to CME Group for entitlement.

For entitling your SFTP Public Key, please provide the file / string to dataplatforms.product@cmegroup.com and expect a 24 hour turnaround time.
