How many identifiers can we include in a request of Symbology API? - I'd like to retrieve the corresponding PermIDs from as many DUNS Numbers as possible in one request.

Also, are there any restrictions on the numbers of requests per second/day/month?

    IMPORTANT UPDATE - unfortunately, the use of DUNS numbers as an input or output in discovery/symbology/v1 API will not longer be permitted due to usage restrictions.

    Hello @hiroko.yamaguchi1

    The endpoint discovery/symbology/v1/lookup should be used for this kind of request.

    For requests that involve simple navigations like organisation level identifier (DUNS code) to Organisation PermID you can include around 1000 inputs per request.

    The max number of inputs should be reduced if the navigation is more complex and involves e.g. traversing multiple relationships, else performance will be reduced.

    Note - DUNS numbers can be use as an input to a query to navigate to another identifier e,g, to PermID, but we don't allow navigations where DUNS number is the output of a navigation due to licensing restrictions.

    I will check and update separately on throttles.
