Agent Self-Signup
Overview
Agents can self-register for an Inkbox account without a pre-existing API key. The self-signup flow provisions a mailbox, identity, and API key in a single call. A verification email is sent to the specified human for approval.
The flow has four steps:
- Register — create the agent (public, no auth)
- Verify — submit the 6-digit code the human received
- Resend Verification — re-send the code if needed
- Check Status — poll claim status and restrictions
Important: Always confirm with the user before initiating a signup, as it sends a real email to the specified human.
Harness & plugins
Signup accepts an optional harness field — a free-form string naming the agent
runtime you're calling from (e.g. claude-code, codex, openclaw, hermes,
cursor, windsurf, cline, aider, continue, gemini-cli, goose,
devin, copilot, roo, zed, replit, amp). Any value is accepted; it's
trimmed and lowercased server-side, and unknown harnesses are never rejected.
After verify succeeds, read the response's message. When a plugin exists for
your harness, the message includes guidance pointing you at the matching plugin
repo. (There is no separate next_steps field — the guidance is folded into
message.)
The four published plugins:
After verify succeeds, read the message and follow any plugin guidance it
contains. Ask your human for permission before you start any plugin setup or
local porting — once they approve, you can do it yourself. If a plugin exists for
your harness, set it up; if not, review the listed plugins and port the relevant
logic locally. The plugin wires Inkbox in as a native channel of your harness —
email, SMS, voice, iMessage, contacts, and notes available directly from your
runtime instead of raw API calls.

SDK Examples
Python
All signup methods are class methods on Inkbox — no instance required.
human_email and note_to_human are required. display_name, agent_handle, and
email_local_part are optional.
from inkbox import Inkbox
result = Inkbox.signup(
human_email="john@example.com",
note_to_human="Hey John, this is your sales bot signing up!",
display_name="Sales Agent",
agent_handle="sales-agent",
email_local_part="sales.agent",
harness="claude-code",
)
api_key = result.api_key
email = result.email_address
handle = result.agent_handle
org_id = result.organization_id
verify = Inkbox.verify_signup(api_key, verification_code="483921")
resend = Inkbox.resend_signup_verification(api_key)
status = Inkbox.get_signup_status(api_key)
Using the API key after signup:
with Inkbox(api_key=api_key) as inkbox:
identity = inkbox.get_identity(handle)
identity.send_email(
to=["john@example.com"],
subject="Hello from your agent!",
body_text="I'm all set up.",
)
TypeScript
All signup methods are static methods on Inkbox — no instance required.
humanEmail and noteToHuman are required. displayName, agentHandle, and
emailLocalPart are optional.
import { Inkbox } from "@inkbox/sdk";
const result = await Inkbox.signup({
humanEmail: "john@example.com",
noteToHuman: "Hey John, this is your sales bot signing up!",
displayName: "Sales Agent",
agentHandle: "sales-agent",
emailLocalPart: "sales.agent",
harness: "claude-code",
});
const apiKey = result.apiKey;
const email = result.emailAddress;
const handle = result.agentHandle;
const orgId = result.organizationId;
const verify = await Inkbox.verifySignup(apiKey, { verificationCode: "483921" });
const resend = await Inkbox.resendSignupVerification(apiKey);
const status = await Inkbox.getSignupStatus(apiKey);
Using the API key after signup:
const inkbox = new Inkbox({ apiKey });
const identity = await inkbox.getIdentity(handle);
await identity.sendEmail({
to: ["john@example.com"],
subject: "Hello from your agent!",
bodyText: "I'm all set up.",
});
Direct API (curl)
Base URL: https://inkbox.ai/api
Register (no auth required)
curl -X POST https://inkbox.ai/api/v1/agent-signup \
-H "Content-Type: application/json" \
-d '{
"human_email": "john@example.com",
"note_to_human": "Hey John, this is your sales bot signing up!",
"display_name": "Sales Agent",
"agent_handle": "sales-agent",
"email_local_part": "sales.agent",
"harness": "claude-code"
}'
human_email and note_to_human are required. display_name, agent_handle,
email_local_part, and harness are optional.
Response:
{
"email_address": "sales-agent-a1b2c3@inkboxmail.com",
"organization_id": "org_...",
"api_key": "ik_live_...",
"agent_handle": "sales-agent-a1b2c3",
"claim_status": "UNCLAIMED",
"human_email": "john@example.com",
"message": "Agent created successfully."
}
Save the api_key — it is shown only once.
Note: The organization_id returned at signup may change after verification or human approval. The /verify and /resend-verification endpoints both return the current organization_id — always prefer the most recent value over the one from the initial signup.
Verify
curl -X POST https://inkbox.ai/api/v1/agent-signup/verify \
-H "Content-Type: application/json" \
-H "X-API-Key: ik_live_..." \
-d '{ "verification_code": "483921" }'
The verification code expires after 48 hours. Max 5 attempts before a resend is required.
Resend Verification
curl -X POST https://inkbox.ai/api/v1/agent-signup/resend-verification \
-H "X-API-Key: ik_live_..."
5-minute cooldown between resends.
Check Status
curl https://inkbox.ai/api/v1/agent-signup/status \
-H "X-API-Key: ik_live_..."
Response:

"claim_status": "UNCLAIMED",

"human_email": "john@example.com",
"restrictions": {
"max_sends_per_day": 10,
