# FAQs about Partner Nodes

> Some FAQs you may encounter when using Partner Nodes.

This article addresses common questions regarding the use of Partner nodes.

<AccordionGroup>
  <Accordion title="Why can't I find the API nodes?">
    Please update your ComfyUI to the latest version (the latest commit or the latest [desktop version](https://www.comfy.org/download)).
    We may add more API support in the future, and the corresponding nodes will be updated, so please keep your ComfyUI up to date.

    <Tip>
      Please note that you need to distinguish between the nightly version and the release version.
      In some cases, the latest `release` version may not be updated in time compared to the `nightly` version.
      Since we are still iterating quickly, please ensure you are using the latest version when you cannot find the corresponding node.
    </Tip>
  </Accordion>

  <Accordion title="Why can't I use / log in to the API Nodes?">
    API access requires that your current request is based on a secure network environment. The current requirements for API access are as follows:

    * The local network only allows access from `127.0.0.1` or `localhost`, which may mean that you cannot use the API Nodes in a ComfyUI service started with the `--listen` parameter in a LAN environment.
    * Able to access our API service normally (a proxy service may be required in some regions).
    * Your account does not have enough [credits](/interface/credits).
  </Accordion>

  <Accordion title="Why can't I use API node even after logging in, or why does it keep asking me to log in while using?">
    * Currently, only `127.0.0.1` or `localhost` access is supported.
    * Ensure your account has enough credits.
  </Accordion>

  <Accordion title="Can API Nodes be used for free?">
    API Nodes require credits for API calls to closed-source models, so they do not support free usage.
  </Accordion>

  <Accordion title="How to purchase credits?">
    Please refer to the following documentation:

    1. [Comfy Account](/interface/user): Find the `User` section in the settings menu to log in.
    2. [Credits](/interface/credits): After logging in, the settings interface will show the credits menu. You can purchase credits in `Settings` → `Credits`. We use a prepaid system, so there will be no unexpected charges.
    3. Complete the payment through Stripe.
    4. Check if the credits have been updated. If not, try restarting or refreshing the page.
  </Accordion>

  <Accordion title="Are unused credits refundable?">
    Currently, we do not support refunds for credits.
    If you believe there is an error resulting in unused balance due to technical issues, please [contact support](mailto:support@comfy.org).
  </Accordion>

  <Accordion title="Can credits go negative?">
    Credits are not intended to be used as a negative balance or credit line. However, due to race conditions where partner nodes don't always report costs before execution, a single execution may consume more credits than your remaining balance and temporarily result in a negative balance after completion. When your balance is negative, you will not be able to run Partner Nodes until you top up and restore a positive balance. Please ensure you have enough credits before making API calls.
  </Accordion>

  <Accordion title="Where can I check usage and expenses?">
    Please visit the [Credits](/interface/credits) menu after logging in to check the corresponding credits.
  </Accordion>

  <Accordion title="Is it possible to use my own API Key?">
    Currently, the API Nodes are still in the testing phase and do not support this feature yet, but we have considered adding it.
  </Accordion>

  <Accordion title="Do credits expire?">
    Yes, the expiration depends on the type of credits:

    * **Monthly credits**: Expire at the end of your billing period
    * **Top-up credits**: Expire 1 year from the date of purchase
  </Accordion>

  <Accordion title="Can credits be transferred or shared?">
    No, your credits cannot be transferred to other users and are limited to the currently logged-in account, but we do not restrict the number of devices that can log in.
  </Accordion>

  <Accordion title="Can I use the same account on different devices?">
    We do not limit the number of devices that can log in; you can use your account anywhere you want.
  </Accordion>

  <Accordion title="How can I request for my account or information to be deleted??">
    Email a request to [support@comfy.org](mailto:support@comfy.org) and we will delete your information
