18getBlobAndRenderAsImage), run it, and enter your API key in the password input.

20## How it works
29
30 - The server function calls `blob.getJSON("image-test")`.
31 - This `blob.getJSON()` method makes an HTTP request to the Val Town API.
32 - The API returns a Response object containing the JSON data.

3Use OpenAI's chat completion API with [`std/openai`](https://www.val.town/v/std/openai). This integration enables access to OpenAI's language models without needing to acquire API keys.

5For free Val Town users, [all calls are sent to `gpt-4o-mini`](https://www.val.town/v/std/openaiproxy?v=12#L85).
32If these limits are too low, let us know! You can also get around the limitation by using your own keys:
33
341. Create your own API key on [OpenAI's website](https://platform.openai.com/api-keys)
352. Create an [environment variable](https://www.val.town/settings/environment-variables?adding=true) named `OPENAI_API_KEY`
363. Use the `OpenAI` client from `npm:openai`:
