The precedence order is: + +1. Environment variables (highest priority) +2. Configuration file (lower priority) +3. Default values (lowest priority) + +### Configuration File + +Create a file named `config` (with no extension) in the directory where you run the goose-api. The format can be JSON, YAML, TOML, etc. (the `config` crate will detect the format automatically). + +Example `config` file (YAML format): + +```yaml +# API server configuration +host: 127.0.0.1 +port: 8080 +api_key: your_secure_api_key + +# Provider configuration +provider: openai +model: gpt-4o +``` + +### Environment Variables + +All configurations can be set using environment variables prefixed with `GOOSE_API_`. + +```bash +# API server configuration +export GOOSE_API_HOST=0.0.0.0 +export GOOSE_API_PORT=8080 +export GOOSE_API_KEY=your_secure_api_key + +# Provider configuration +export GOOSE_API_PROVIDER=openai +export GOOSE_API_MODEL=gpt-4o + +# Provider-specific credentials (based on provider requirements) +export OPENAI_API_KEY=your_openai_api_key +export ANTHROPIC_API_KEY=your_anthropic_api_key +# etc. +``` + +## API Authentication + +All API endpoints require authentication using an API key.
