Environment Variables

ImageClient.fromEnv() reads:

Provider	Environment variable
OpenAI	OPENAI_API_KEY
Google Gemini API	GEMINI_API_KEY

OPENAI_API_KEY=sk-...
GEMINI_API_KEY=...

GOOGLE_API_KEY is not read by default. The explicit name avoids ambiguity with other Google APIs.

If you use another secret name, pass keys explicitly:

const client = new ImageClient({
  apiKeys: {
    google: process.env.GOOGLE_API_KEY,
  },
});

Missing Google keys throw an authentication error explaining that GEMINI_API_KEY or apiKeys.google is required.
