Available Periods
If you are unsure which periods are available, you can use the periods endpoint. For example, here is how to retrieve the periods for which Canon submitted an archive:
[Public datalake] List available periods for Canon
curl -X GET "http://secxbrl.28.io/v1/_queries/public/api/periods?ticker=7751&profile-name=japan&token=c3049752-4d35-43da-82a2-f89f1b06f7a4"
You can use all parameters from the entities endpoint, as well as archiveFiscalYear and archiveFiscalPeriod to filter by the one or the other.
