For setting up the OpenHands Software Agent SDK locally, which API key should I use?

You need an LLM key, you can use from Cloud yes, or any key from the LLM you'd like to use

I think I need to set up the LLM, but what should I add in the API key?

Ah, wait. • to run the SDK locally, you do not have to fill in that page at all • you can get an API key from the Api Keys page ( https://app.all-hands.dev/settings/api-keys ) and that's it, you're done with the cloud for now • then use it with the SDK locally

@calm-artist-7206 Thanks for your helpful answer and quick reply. Is my understanding correct? I'm getting the same error — is it because it's expecting an Anthropic API key, but I'm using the OpenHands Cloud key

You can use OH Cloud key, and access Anthropic. Do I understand correctly the

echo

, you didn’t have LLM_API_KEY set? The OH cloud key should be the value of LLM_API_KEY

The LLM is set, and it's the same as the OH Cloud key.

LLM_API_KEY=this_llm_key should be in env

this one from the api key section

In the API keys page, there are 2 sections though

Both give me the same error. I previously tried the OH API keys

Should be OH LLM key, not “pure API”

Huge thanks, @calm-artist-7206 — now it works. I’m not sure how the SDK works. I followed the documentation, and they suggested running the command:

uv run python examples/01_standalone_sdk/01_hello_world.py

I think in the example the provider is set to Claude.

(Just to note, you can always use it with Anthropic account too, you just have to set the right provider then, “anthropic/“ prefix. It just means “openhands/“ prefix uses the models via OH Cloud. I think for anthropic models in particular, OH Cloud has much better rate limits than regular accounts that access Claude directly from Anthropic itself, so it’s kinda cool)

Anything in particular you're trying to do with the SDK?
