<AccordionGroup>
  <Accordion title="Actor">
    The entity that performs an action within your account. An actor can be a registered user (e.g., `you@example.com`), an API Token (e.g., `API Token: "My Scraper"`), or the `System` itself (for automated actions). You can see the actor for each event in your **[Event Log](https://2extract.com/app/profile)**.
  </Accordion>

  <Accordion title="ASN (Autonomous System Number)">
    A unique number assigned to an Internet Service Provider (ISP). Targeting by ASN (`-asn-[number]`) allows you to get IP addresses from a specific network provider, such as Comcast or AT\&T.
  </Accordion>

  <Accordion title="Authorized IPs (IP Whitelist)">
    A security feature that restricts proxy access to a list of pre-approved IP addresses. Requests from IPs not on this list will be rejected, even with valid credentials. This can be configured for each individual **Proxy**.
  </Accordion>

  <Accordion title="Balance">
    Your central account wallet in USD. Funds are added via top-ups and are used to pay for **Pay-As-You-Go** traffic and any overage from subscription plans. You can manage it on your **[Billing](https://2extract.com/app/billing)** page.
  </Accordion>

  <Accordion title="Carrier">
    A mobile network operator (e.g., T-Mobile, Verizon, Vodafone). Carrier targeting (`-carrier-[name]`) is a feature exclusive to **Mobile Proxies**.
  </Accordion>

  <Accordion title="Mobile Proxy">
    An IP address from a real mobile device on a 3G/4G/5G cellular network. Mobile proxies offer the highest level of trust and are ideal for targeting mobile-first websites and social media.
  </Accordion>

  <Accordion title="Pay-As-You-Go (PAYG)">
    A flexible billing plan where you are charged only for the traffic you consume. The cost is deducted from your main account **Balance**.
  </Accordion>

  <Accordion title="Proxy">
    Your personal, configurable gateway to our network. Each proxy you create has its own unique credentials, plan, security settings, and usage statistics. This allows you to manage different projects independently.
  </Accordion>

  <Accordion title="Residential Proxy">
    An IP address from a real desktop or laptop device connected to a genuine home Wi-Fi or cable network (ISP). These proxies are highly trusted and excellent for most web scraping tasks.
  </Accordion>

  <Accordion title="Rotation">
    The process of changing the IP address used for your requests.

    * **Per-Request Rotation (Default):** You get a new IP for every request.
    * **Sticky Session:** You keep the same IP for multiple requests.
  </Accordion>

  <Accordion title="Session">
    A series of requests made from the same IP address. You can create a **Sticky Session** using the `-session-[id]` parameter.
  </Accordion>

  <Accordion title="Status">
    The current state of your proxy:

    * **Active:** The proxy is running and ready to use.
    * **Inactive:** The proxy has been manually paused by you and will not accept connections.
    * **Suspended:** The proxy has been automatically stopped, either due to reaching a usage limit or a zero account balance.
  </Accordion>

  <Accordion title="Subscription">
    A recurring billing plan (e.g., "Starter 30GB") that provides a set amount of traffic for a fixed monthly fee. Subscription plans will be available in a future update.
  </Accordion>

  <Accordion title="Target Whitelist">
    A security feature for a specific **Proxy** that allows it to connect only to a predefined list of domains or hostnames (e.g., `google.com`, `*.wikipedia.org`).
  </Accordion>

  <Accordion title="Username Parameters">
    Special suffixes (like `-country-de` or `-session-user123`) that you can add to your proxy's username to control its behavior (e.g., geo-targeting, session type) in real-time for each request.
  </Accordion>
