# Anthropic API key (/connect/use-your-own-keys/connect-anthropic-api-key)



## What is an Anthropic API key? [#what-is-an-anthropic-api-key]

With a Anthropic API key, Helio stores one workspace credential and exposes selected Claude Opus and Claude Sonnet models to compatible AI teammates. Usage is billed to your Anthropic account, not to Helio-managed access.

## How to Connect an Anthropic API Key [#how-to-connect-an-anthropic-api-key]

<Steps>
  <Step>
    ### Create or copy the API key from Anthropic Console [#create-or-copy-the-api-key-from-anthropic-console]

    Open [Anthropic Console](https://console.anthropic.com), sign in, go to **API Keys**, create a new key, and copy it once. Keep the provider page open until Helio confirms the key works; most providers show the secret only at creation time.

    <LivePreview component="ModelsSettings" />
  </Step>

  <Step>
    ### Open Models in Helio [#open-models-in-helio]

    In Helio, go to **Settings → Workspace → Models**. This is the page where API keys and subscription logins become model sources for AI teammates.

    <LivePreview component="ModelsSettings" />
  </Step>

  <Step>
    ### Add a provider [#add-a-provider]

    Click **Add Provider**, then choose **Anthropic**. Do not choose a different provider just because the model names look similar: the key must match the provider you generated it from.

    <LivePreview component="ModelsSettings" scenario="{ dialog: &#x22;provider&#x22; }" />
  </Step>

  <Step>
    ### Paste the key and label it clearly [#paste-the-key-and-label-it-clearly]

    Paste the API key, then use a label that explains who owns the budget or what it is for, such as `prod-anthropic` or `growth-anthropic`. The label is what teammates see later in model pickers.

    <LivePreview component="ModelsSettings" scenario="{ dialog: &#x22;provider&#x22; }" />
  </Step>

  <Step>
    ### Select the models you want to expose [#select-the-models-you-want-to-expose]

    After Helio verifies the key, select only the models your team should be allowed to use. Save the provider. Those selected models now appear under this credential in teammate model pickers.

    <LivePreview component="ModelsSettings" scenario="{ dialog: &#x22;provider&#x22; }" />
  </Step>

  <Step>
    ### Assign a model to an AI teammate [#assign-a-model-to-an-ai-teammate]

    Open the AI teammate's **Teammate Settings → Profile → Models**. Choose a Claude Opus and Claude Sonnet models option listed under your saved Anthropic credential, then save. Anthropic keys power **Claude Code** teammates; if the teammate uses a different engine, hire or switch to a compatible teammate first.

  </Step>
</Steps>

<Callout type="info">
  Helio does not show the raw API key after you submit it. If the key leaks, expires, or should change owners, rotate it in the provider console and update the credential in Helio.
</Callout>

## If the model does not appear [#if-the-model-does-not-appear]

* Confirm you saved the provider after selecting models.
* Confirm the AI teammate's engine is compatible with Anthropic.
* Confirm the key has enough provider-side permissions and billing enabled.
* Reopen **Settings → Workspace → Models** and check whether the credential shows an error.
