## The Credit System

Because SignalArk heavily utilizes Large Language Models (LLMs) and premium external data APIs (like PDL and Exa) to generate high-quality intelligence, specific actions consume **Credits**.

When your balance is insufficient for a specific action, the UI will disable the action button and display a warning.
