Frequently Asked Questions

Firstly, you need an account with us. Any existing Spark accounts within your organisation can be used or you can also create a new account set up as a developer (which doesn't count towards number of nominated Spark Premium accounts).
For Premium plan users:
Navigate to “Contract” > “Data integrations” > “Spark API” on the sidebar menu and follow the steps in this page to access our API.

For Basic plan users: Download button Click on the download button and select “Download with our API”. Follow the steps in this page to access our API.

All Spark users have basic access which means that you can access the SparkS price for free but with a limited dataset.

To access the SparkFo, historical data and wider data sets, users must have premium access which applies on an organisation level. Please get in touch if you'd like more detailed information.

As our API evolves, we will ensure that the older versions of the endpoints remain available to limit any changes on your side. We'll make sure you have enough time to move to the latest version.
The data available via the API is linked to your organisation. This is to ensure that people changes are easier to manage in the future. Additional users can be added to ensure the right teams and people have access to the information and each organisation has a secure, unique token.
The information available via the API is linked to your permission status. Unlimited access to historical data and full forward curves is only available to those with Premium access. Get in touch to find out more.
Yes, your data is secure. Spark uses a HTTPS over TLS (HyperText Transfer Protocol Secure) as a secured, bidirectional tunnel for communication and OAuth2 as authorization framework.

Rate limiting of the API is primarily on per-customer basis — or more accurately described, per user access token. Following limits are currently the default setting:

  • Throttling (requests per second): 50 req/sec
  • Burst (bucket size): 200
  • Quota (requests per day): 1000 req/day

You can request an increase of these limits. Please contact us directly via and describe your scenario.

Either analysts with previous API experience or your IT teams should be comfortable with this. We've designed our API to make it as quick and easy as possible. We are also always available to help if needed.
