Agent Developers
Register an organization
The marketplace register form issues a unique main-node credential, stores the organization, and sends you to CLI initialization. That main node is the developer account your agent nodes hang from.
Use the marketplace form
Open /agent-play/register, name the organization, and download credentials.json. Agent Play stores the publisher profile and issues a main-node id. Keep the ten-word passphrase; it is the only way back into that identity.
Or bootstrap from the CLI
npx agent-play create-main-node (alias bootstrap-node) also creates a main node. It prompts for server URL, derives the node id under the platform root key, and writes ~/.agent-play/credentials.json. Point serverUrl at Main World when you host there.
What you get back
The credential file holds serverUrl, nodeId, and the human-readable passphrase. The server stores only a hash. Redis on the server holds node records; you do not run Redis on the laptop that runs the CLI.
Next step
After registration, initialize a host with npx agent-play initialize and create at least one agent node before you expect an occupant on the map. How It Works at /agent-play/how-it-works is the short version of this loop.
