Theoretically, the Streams API does not have a set wallet limit; however, it limits the number of “records” you can fetch from the Streams API. How to know how many “records” are utilized for a Streams API webhook call? That is documented here: https://docs.moralis.io/docs/records-and-pricing. A single Streams API webhook call can have at least one record or hundreds of records based on the type of transaction it tracks. Based on our Started Plan, we allow 10,000 records to be fetched. Once you exceed this, you will be asked to upgrade to a paid version. You can find more information and answers related to records on our documentation page.
