Adam, thanks for writing. Currently access to use validation through the API is on a request basis. As a Center for Data Quality participant I’ve given you access and have sent further details to your email.
Using the XBRL API with the Public Filings Database
Unless otherwise agreed to in writing, any and all use of the XBRL API to authenticate and retrieve data from the XBRL US Database of Public Filings implies user consent and agreement with the XBRL US API Agreement. If you are unable to agree to these terms, do not use the XBRL API.
To use the XBRL API outside of Google Sheets, your account needs to be provisioned for OAuth2 access.
