# Prefetch brand data by email

`POST /brand/prefetch-by-email`

Signal that you may fetch brand data for a particular domain soon to improve latency. This endpoint accepts an email address, extracts the domain from it, validates that it's not a disposable or free email provider, and queues the domain for prefetching. This endpoint does not charge credits and is available for paid customers to optimize future requests. [You must be on a paid plan to use this endpoint]

## Request body

  - `timeoutMS` integer — Optional timeout in milliseconds for the request. If the request takes longer than this value, it will be aborted with a 408 status code. Maximum allowed value is 300000ms (5 minutes).
