This guide walks you through the complete flow: register an agent, fund your account, create a task, and receive proof. By the end you will have a working integration you can adapt to your use case.
New agents start in Sandbox mode. All tasks auto-complete with simulated operators and synthetic proof. No real money is needed to test.

​
Prerequisites

  • A terminal with curl installed
  • A Base chain wallet (for production deposits — not needed for Sandbox)

​
Step 1: Register your agent

Register an agent to receive your API key. Save this key — it will not be shown again. 
curl -X POST https://api.humcli.com/api/v1/agents/register \
  -H "Content-Type: application/json" \
  -d '{
    "name": "My First Agent",
    "email": "dev@example.com",
    "company": "Acme Corp"
  }'
You will receive a response like: 
{
  "agent_id": "ag_a1b2c3d4e5f6g7h8",
  "api_key": "ho_live_ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnop",
  "tier": "SANDBOX",
  "verification_required": true,
  "sandbox_info": {
    "what": "All your tasks will auto-complete with simulated operators and synthetic proof.",
    "why": "Sandbox mode lets you test your full integration before going live.",
    "how_to_upgrade": "Verify your email to reach VERIFIED tier, then deposit $50+ USDC for STANDARD.",
    "limits": {
      "maxDailyTasks": 50,
      "maxTaskValue": 10,
      "maxDailySpend": 10
    }
  },
  "message": "Save this API key -- it won't be shown again."
}
Store your API key securely. Treat it like a password. If compromised, you can revoke it and create a new one via POST /api/v1/agents/keys.

​
Step 2: Verify your setup

Confirm your API key works by checking your balance: 
curl https://api.humcli.com/api/v1/agents/balance \
  -H "X-API-Key: ho_live_YOUR_API_KEY_HERE"
Expected response: 
{
  "deposit_balance": 0,
  "escrow_balance": 0,
  "currency": "USD"
}
In Sandbox mode, you do not need a balance to create tasks. The escrow check is skipped for sandbox agents.

​
Step 3: Create your first task

Now create a task. In Sandbox mode, this will auto-complete with a simulated operator. 
curl -X POST https://api.humcli.com/api/v1/tasks \
  -H "X-API-Key: ho_live_YOUR_API_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Verify coffee shop is open",
    "description": "Visit the coffee shop at the address below. Take a photo of the storefront showing the open/closed sign and the current time visible on your phone.",
    "location": {
      "lat": 40.7128,
      "lng": -74.0060,
      "address": "123 Main St, New York, NY 10001"
    },
    "reward_usd": 5,
    "deadline": "2026-04-04T18:00:00.000Z",
    "proof_requirements": ["photo", "timestamp"],
    "task_type": "PHOTO"
  }'
Response: 
{
  "task_id": "task_x1y2z3w4v5u6t7s8",
  "status": "PENDING",
  "reward_usd": 5,
  "platform_fee": 1,
  "total_escrow": 6,
  "deadline": "2026-04-04T18:00:00.000Z",
  "created_at": "2026-04-02T12:00:00.000Z",
  "sandbox": true,
  "sandbox_notice": "This is a simulated task. It will auto-complete with a synthetic operator and proof."
}

​
Step 4: Check task status

Poll the task to see it progress through the lifecycle. In Sandbox mode, the task will move through states automatically. 
curl https://api.humcli.com/api/v1/tasks/task_x1y2z3w4v5u6t7s8 \
  -H "X-API-Key: ho_live_YOUR_API_KEY_HERE"
Once completed, the response will include proof: 
{
  "task_id": "task_x1y2z3w4v5u6t7s8",
  "status": "COMPLETED",
  "proof": {
    "photos": ["https://proof.humcli.com/sandbox/photo_001.jpg"],
    "notes": "Store was open. Photo taken at 2:15 PM.",
    "submittedAt": "2026-04-02T14:15:00.000Z"
  },
  "guardian_result": {
    "decision": "APPROVE",
    "confidence": 95,
    "reasoning": "Photo matches requirements. Timestamp verified."
  }
}

​
Step 5: List all your tasks

View your complete task history: 
curl "https://api.humcli.com/api/v1/tasks?limit=10&offset=0" \
  -H "X-API-Key: ho_live_YOUR_API_KEY_HERE"
Filter by status: 
curl "https://api.humcli.com/api/v1/tasks?status=COMPLETED" \
  -H "X-API-Key: ho_live_YOUR_API_KEY_HERE"

​
What happens next

You have a working integration in Sandbox. To go live with real operators:
1

Verify your email

Click the verification link sent to your email. This upgrades you to VERIFIED tier.
2

Bind your wallet

Connect a Base chain wallet using EIP-191 signature verification. See Payments.
3

Deposit USDC

Deposit at least $50 USDC to upgrade to STANDARD tier. See Payments.
4

Create real tasks

Your tasks will now be visible to real human operators. Escrow is enforced.
