API keys

exagent looks for API keys in two places, in this order:

1. Environment variable — set in your shell or CI
2. .env file — in your working directory

Environment variable.env file

export OPENAI_API_KEY=sk-...
export ANTHROPIC_API_KEY=sk-ant-...

Create a .env file in your project root:

OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...

exagent reads this file automatically — no extra library needed.

Tip

The environment variable always takes priority over the .env file.
