## Issue a Bridger API Key

<Steps>
  <Step title="Open the admin dashboard">
    Create an account at [admin.datari.kr](https://admin.datari.kr).
    Google / Kakao social login is supported.
  </Step>

  <Step title="Create an API key">
    Click **Settings → API Keys → Create new key** and it's issued instantly.
  </Step>

  <Step title="Store the key securely">
    The issued key is shown only once. Store it in an environment variable or a secret manager (e.g. Vault).

    ```bash theme={null}
    export DATA_BRIDGE_API_KEY="dk_live_..."
    ```
  </Step>
</Steps>

## Apply for a data.go.kr service key

Many of the public-data APIs that Bridger calls require a
[Public Data Portal (data.go.kr)](https://www.data.go.kr) service key. A single service key can often
be reused across multiple APIs from the same provider.

<Steps>
  <Step title="Sign up at data.go.kr">
    Register on the [sign-up page](https://www.data.go.kr/uim/psi/mem/joinIdPwSlct/view.do).
    Skip this step if you already have an account.
  </Step>

  <Step title="Click &#x22;Apply&#x22; on the API you want">
    Press the **Apply** button for the API you want, from the Provider Keys screen in
    [admin.datari.kr](https://admin.datari.kr) or on data.go.kr.

    <Tip>You can keep the purpose of use brief. (e.g. "Data lookup for an AI service")</Tip>
  </Step>

  <Step title="Copy the service key after approval">
    Most APIs are **approved instantly**. After approval, copy the
    **general key (Decoding)** from
    [My Page → Usage management](https://www.data.go.kr/iim/api/selectAPIAcInfo.do).

    <Warning>
      Always use the **Decoding** key. The Encoding key (URL-encoded form) is not used by Bridger.
    </Warning>
  </Step>

  <Step title="Enter the key in Bridger">
    Enter the copied service key under **Settings → Provider Keys** in the Bridger admin dashboard
    and you can start using it. A single service key can often be used across multiple APIs from the
    same provider.
  </Step>
</Steps>

## Frequently asked questions

<AccordionGroup>
  <Accordion title="My access application isn't approved">
    Most are auto-approved instantly, but some APIs require provider review. They're usually approved within 1–3 days.
  </Accordion>

  <Accordion title="I have multiple keys — which one do I use?">
    Use the **general key (Decoding)**. The Encoding key is URL-encoded, and Bridger only uses the Decoding key.
  </Accordion>

  <Accordion title="Can I use an API that isn't listed here?">
    Any API with an OpenAPI spec can be registered directly via [BYOAPI](/en/concepts/byoapi). (coming soon)
    If you'd like your API added as a public preset, contact us at [support@datari.kr](mailto:support@datari.kr) or via Channel Talk.
