| # .env.example — Multi-LLM-API-Gateway | |
| # Copy this file to .env and fill in the values. | |
| # IMPORTANT: Never commit the .env file to version control. | |
| # =========================================== | |
| # ARCHITECTURE NOTE: | |
| # The Guardian (main.py) is the ONLY process that reads this file. | |
| # app/* modules NEVER touch .env — they get ENV-VAR NAMES via app/.pyfun | |
| # and the values are read with os.getenv() inside the sandbox boundary. | |
| # | |
| # No key set = provider skipped = tool not registered = NO CRASH. | |
| # =========================================== | |
| # --- LLM Provider Keys --- | |
| # Which providers activate is defined in app/.pyfun [LLM_PROVIDERS]. | |
| # A provider only registers when its ENV key here is set. | |

| # =========================================== | |
| # --- Database Connection (PostgreSQL) --- | |
| # The complete Data Source Name (DSN) for your PostgreSQL database. | |
| # This works for both local instances and cloud providers like Neon.tech. | |
| # Example for Neon: postgresql://user:password@host.eu-central-1.aws.neon.tech/neondb?sslmode=require | |
| # Example for local: postgresql://user:password@localhost:5432/mydb | |
| # Leave empty or comment out if your app doesn't need database | |
| DATABASE_URL="your_database_dsn_here" | |
| # --- Application-Level Encryption Keys --- | |
| # These keys are used by the application itself to encrypt sensitive data | |
| # before it is written to the database. | |
| # The master key must be a 256-bit key (32 bytes). | |
| MASTER_ENCRYPTION_KEY="your_256_bit_key_here" | |
| # The salt is a unique, persistent value used with the master key. | |
| # It should also be a secure, random string. | |

| # =========================================== | |
| # LOGGING CONFIGURATION (Optional) | |
