Google Gemini setup has three parts: create an API key using Google's documented flow, connect it to the workspace, and verify a real low-risk agent run. DeployHermes supports pasting and validating a Google provider key before it is sealed.

## Create a Google API key with the right owner

Follow Google's Gemini API key guide and choose the account or project that should own usage and access. Keep the key out of source control and do not send it through Telegram or another chat channel. A workspace credential should have a clear operator and a rotation plan.

Review Google's current model documentation when selecting a model policy. Model names, availability, and behavior can change; a permanent page should not promise a particular catalog snapshot.

## Paste, validate, and seal

In DeployHermes provider settings, choose Google and paste the key. The connection flow validates the credential against Google's models API, then stores the sealed value rather than returning it to the browser. A provider status row is an authentication status, not a guarantee that every request will be accepted.

After connecting, select Google in the agent's provider policy and send a test request with no external side effect. Confirm the run result before attaching the agent to a larger workflow.

## Diagnose the boundary that failed

A rejected key belongs to the Google credential boundary. A model-policy error belongs to the runtime configuration. A successful run with no Telegram response belongs to channel delivery or pairing. Keep these diagnoses separate so you do not rotate a good key to solve a routing problem.

If the provider is no longer needed, disconnect it from the workspace and remove unused keys through Google's account controls. DeployHermes is an independent runtime that uses the provider access you authorize.

## Frequently asked questions

### Does DeployHermes store my Google key in the browser?

The connection action validates the pasted key and seals it in the backend. The UI receives a non-secret account label rather than the key.

### Do I need a different Google key for every agent?

Not necessarily. Choose a workspace ownership and access policy that fits your risk and usage needs, then scope each agent's provider policy deliberately.
