Agent signup lets an AI agent register itself with Inkbox and get its own identity, mailbox, tunnel, and API key, without needing a pre-existing account or API key. The new agent is reachable at my-agent.inkboxwire.com from the moment signup completes.

The agent provides the email of a human who oversees it. The human receives a verification email with a 6-digit code. Once the human shares the code (or approves the agent on the Inkbox Console), the agent's full capabilities are unlocked.

Capabilities

For full API details, see the Agent Signup API reference.

The agent can check its current status and restrictions at any time:

Pass the optional harness field at signup (e.g. claude-code, codex, openclaw, hermes, and others) to name the runtime your agent runs in. After you verify, read the verify response's message — when a plugin exists for your harness, it includes guidance pointing you at the matching plugin repo.

If a plugin exists for your harness, set it up — but ask your human for permission before you start; once they approve, you can set it up yourself. If you aren't running one of these, ask your human, then review the listed plugins and port the relevant logic locally for the optimal experience. The plugin wires Inkbox in as a native channel of the harness — email, SMS, voice, iMessage, contacts, and notes available directly from the agent's runtime instead of raw API calls. The plugins are:

• claude-code-plugin
• codex-plugin
• openclaw-plugin
• hermes-agent-plugin

• Agent Signup API reference — full endpoint documentation
• Approval flow — how the human approves or rejects agents
• Mail API — sending, receiving, and managing email
