user88344: I'd like to create a pool of addresses using Blockchain.com API.
But because of the gap limit on unused addresses I want to transfer minimal amount (ideally 1 Satoshi) and without any fees.
What's the easiest way to send small amount of BTC to thousands of addresses?
I don't care about speed as this is a background operation.
UPD: This is NOT a question "how to create addresses?" this is a question how to distribute small amount of money to multiple addresses with minimal fees. It is not related to  any service provider, Blockchain.com was indicated as a context only.

user7272: The only way to do this is by making a regular transaction with lots of outputs. Moreover, you will have great difficulty broadcasting a transaction with outputs of 1 Satoshi due to the dust limit.
A far easier solution would be to switch to a wallet provider that allows you to bypass the gap limit, such as bitgo (although it may be restricted to their commercial offering), or build your own transaction indexing system
