# Retrieve a Prompt

> Fetch a saved prompt by name or ID, optionally a specific version, and compile it with dynamic variables via the SDK or API

Once a prompt exists in Prompt Hub, your application fetches it at runtime instead of hardcoding the text. You can look it up by name or by ID, and optionally ask for a specific version - if you don't, you get the latest available content. If you don't ask for compilation, you get the raw prompt text back untouched, including any `{{variableName}}` placeholders still in place.

## Dynamic variables

Any `{{variableName}}` placeholder in a prompt's content is replaced with the value you pass at fetch time when compilation is enabled. It's plain text substitution - there's no escaping, no nested variables, and no default values, so make sure you pass a value for every placeholder the prompt uses.

Every fetch is counted, so the Downloads column on the prompt list and the per-version counts on the [Versions tab](/latest/openlit/prompts-experiments/prompt-hub/versioning) reflect real usage from your application.

## Create an API key

To authenticate SDK or API requests, you need an API key:

<Steps>
  <Step title="Create an API Key">
    * Go to OpenLIT and navigate to the **API Keys** page.
    * Click **Create API Key**.
    * Enter a name for your API key.
    * Save the key displayed - store it securely, since you'll pass it to the SDK for authentication.
  </Step>
</Steps>
