24/7 Cryptocurrency Market Data Access
Technology
24/7 cryptocurrency market data is built upon Representation State Transfer (REST) web service technology. In this methodology, HTTP URLs and methods (such as GET, POST, etc.), parameters, and statuses are used to model the remote procedure call behavior.
The implementation utilizes the industry standard JSON format with custom CME Group extensions.
HTTP Usage
Users send Query Requests by invoking the HTTP POST method to a URL of the form https://{{Path}}/streaming/v1/btcindexJson?
where CME Group assigns {{Path}}
and communicates it to the user. Connections to the API utilize HTTPS to provide security. Users transmit a username and password, assigned by CME Group, via HTTP Basic authentication.
Access is defined at the dataset level, in JSON format, through a group and role-based entitlement system.
- Users accessing 24/7 cryptocurrency market data through a web browser can use the following curl request:

Streaming Criteria
Users can append streaming criteria to the end of the url to query certain streaming data.
...
Criteria Definition | Type | Value | Required | Description |
---|---|---|---|---|
seek | Int | YYYYMMDDhhmmssSSS | N | Returns streaming data starting from the timestamp specified on the request up to the current time, then continues streaming real time market data. Note: The seek request can only retrieve data streamed within the past 24 hours. The timestamp from which to initiate streaming must be in milliseconds and UTC format. Not including this argument starts streaming from the current moment. Example: https://datamine.api.cmegroup.com/streaming/v1/btcIndexJson?seek=20161115093023000 |
