Local command
npx -y @reinconsole/[email protected]Credentials from the publisher
- REIN_AGENT_FILE — Path to the rein-agent.json written by `npx @reinconsole/init` (engine URL, agent id, API key, wallet).
- REIN_ENGINE_URL — Policy engine base URL. Required unless REIN_AGENT_FILE is set.
- REIN_AGENT_ID — The one agent this server speaks for. Required unless REIN_AGENT_FILE is set.
- REIN_ENGINE_API_KEY — Bearer key for the engine, ideally an evaluate key narrowed to this agent.
- REIN_PAYER_PRIVATE_KEY — Agent wallet key. Omit for advisory mode: policy is checked, nothing is paid.
- REIN_NETWORK_PROFILE — testnet (default) or mainnet: which network's 402s this server will pay.
