Getting your credentials

  1. Sign in to Google AI Studio with the Google account you want to use.
  2. Open the API key section and create a new key, choosing or creating the Google Cloud project it should belong to.
  3. Copy the key and paste it into the credential’s API Key field in BusyBot.

Keys created in AI Studio are tied to a Google Cloud project, which is where quota and any billing are tracked.

Permissions and scopes

The key inherits access from its Google Cloud project. If the project has restrictions applied to API keys, make sure the generative language API is permitted, otherwise calls are rejected even though the key is valid.

For higher rate limits than the free tier allows, enable billing on the project the key belongs to.

Troubleshooting

  • 403 or permission denied — the API is not enabled on the project, or a key restriction is blocking it. Check the project’s enabled APIs and any key restrictions.
  • 429 rate limited — the free tier’s limits are low. Enable billing on the project for production use, and keep node concurrency modest.
  • Model not found — the model selected on the node is not available to your project or region. Pick a different model from the node’s dropdown.

Frequently asked questions

Is this the same as a Google Cloud service account?

No. This is an API key from Google AI Studio for the generative language APIs. The separate Google API credential uses a service account with an email and private key, and is for Google Workspace and Cloud services.

Can I use one key for all Gemini nodes?

Yes — one Google AI credential covers all 18 nodes that declare it, including chat, embeddings, image generation and code execution.

Why am I being rate limited so quickly?

The free tier has low limits. Enable billing on the Google Cloud project the key belongs to, and keep Max Concurrency low on nodes that process batches.

Where is usage billed?

To the Google Cloud project the key was created in, which is why choosing the right project when creating the key matters.
