Welcome to the API wiki!

As always this wiki will be work in progress.

The API calls is documented here with swagger

Code samples

We created a C# client for you to get a quick start.
If you like code in other program languges you can use swagger to generate the client code.

Rate Limits

The API is rate limited to 100 calls in 10 second.

You will recieve a 429 when exceding the rate limit. Check header Retry-After to see time to wait before next call.

There is no set max limit of api calls, but you should try not to exceed 10K api calls per 24h. It's ok to do more api calls occasionally, but not every day. Please try to stay below 10K per day.

Day Limit

There is no set max limit of api calls, but you should try not to exceed 10K api calls per 24h. It's ok to do more api calls occasionally, but not every day. Please try to stay below 10K per day.

DateTime

All time is given in ISO-8601 UTC

Sample: 2012-04-23T18:25:43.511Z

Best practice

Börsdata update Stockprices and KPIs once a day. The API only support end-day stockprice that Börsdata recieves when the market is closed. The stockdata and KPIs is normaly fully updated after 20:00 UTC time.

  • Only get the data for the companies you need. (Reduce our server load)
  • Call API 20:00 UTC to get today latest data. (Or you will get yesterday data)
  • Respect the Ratelimit. If you get 429, then wait before calling again.
  •   Use Last Stockprice call for daily updates of stockprices.

  •   If you need all reports then use All reports call.

Issues Tracking

We use GitHub's Issues tracker for our project. Feel free to create bug reports and features requests.
Make sure to read the documentation before asking questions - this will avoid repeated questions, leaving us more time for developing the library.
Try keep conversation in English.

Best regards, Börsdata Team
