# How credits work Unlike most keyword tools that charge monthly, Keyword Chef only charges you when you find keywords. This works by purchasing credits, where each keyword returned in your report will cost 1 credit. Each credit includes: * The keyword * Avg, high, and low search volume * The real-time SERP preview and SERP score Looking up the SERP does not cost additional credits. However, for users on the free trial, there is a limit of 30 SERP lookups. Paid users get unlimited SERP lookups. Credits never expire and reports are saved forever. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
