Deploy to CreateOS

No auth session, no OAuth, no browser login required. This skill uses the HTTP 402 payment flow — the on-chain payment itself is the access control. Just call the API, pay with USDC/USDT, and deploy.

Prerequisites

You need an EVM wallet with gas (ETH) and USDC on a supported chain. Generate one if needed:

import { generatePrivateKey, privateKeyToAccount } from "viem/accounts";
const privateKey = generatePrivateKey();
const account = privateKeyToAccount(privateKey);
// Save privateKey securely

Only dependency: npm install viem

Flow

POST /agent/deploy (no payment) — gateway checks credits AND active projects
- Has credits, no active projects → deploys directly, returns 200. Skip to step 5.
- Has credits, has active projects → returns 402 with a warning. The agent must either:
  - Pay to extend total runtime (recommended), OR
  - Retry with header X-Use-Existing-Credits: true to deploy using existing credits (this will reduce runtime of the other active projects)
- No credits → returns 402 with pay_to, amount_token, payment_chain, supported_chains
GET /agent/balance/:address?chain=... — check token balance on each supported chain
If no chain has enough balance, stop and tell the user:

"Your wallet 0x... doesn't have enough funds to deploy. Please add {amount_usd} {token} on {chain} to address 0x...."

Show all supported chains so the user can pick one to fund.
Send ERC20 transfer to pay_to using viem → get txHash POST /agent/deploy with X-Payment-Tx: txHash → verifies payment, topups credits, deploys
GET /agent/deploy/:projectId/:deploymentId/status → poll until ready

Credit Sharing & Active Projects

NodeOps credits are pooled across all your active projects and consumed hourly. When you have multiple active deployments, they share the same credit balance.

If you have 0 active projects and credits: deploys for free, no impact.
If you have 1+ active projects and you deploy without paying, the new project will share the credit pool — reducing runtime of the other projects.
The gateway prevents this by default: if you have active projects, you must either pay (to add fresh credits) or explicitly opt in via X-Use-Existing-Credits: true.

Always tell the user when their deploy will affect other active projects, and recommend paying instead.

Utility Endpoints (no auth required)

Check balance — all tokens on a chain:

GET /agent/balance/0xYourWallet?chain=arbitrum

{
  "address": "0x...",
  "chain": "arbitrum",
  "balances": [
    { "token": "usdc", "symbol": "USDC", "balance": "18.000000", "decimals": 6 }
  ]
}

List supported chains:

GET /agent/chains

{
  "chains": [
    { "chain": "arbitrum", "chain_id": 42161, "tokens": ["usdc", "usdt"] },
    { "chain": "base", "chain_id": 8453, "tokens": ["usdc", "usdt"] }
  ]
}

Auth Headers (all requests)

Sign {wallet}:{timestamp}:{nonce} with your private key.

X-Wallet-Address: 0xYourWallet
X-Signature: 0xSignedMessage
X-Timestamp: 1711500000000
X-Nonce: unique-uuid

List Your Projects (auth required)

GET /agent/projects

Returns all projects deployed by the wallet, with the live URL of the latest deployment for each.

{
  "wallet": "0x5B6C...",
  "count": 2,
  "projects": [
    {
      "id": "uuid",
      "name": "demo-1234567890",
      "displayName": "Demo App",
      "status": "active",
      "url": "https://demo-1234567890.nodeops.network",
      "createdAt": "2026-04-07T10:00:00.000Z"
    }
  ]
}

url will be null if the project has no successful deployment yet. Status values: active, building, deploying, pending, queued, promoting, deleting, failed.

Delete a Project (auth required)

DELETE /agent/projects/{projectId}

Permanently deletes a project from NodeOps. Only the wallet that originally deployed the project can delete it.

{ "projectId": "uuid", "status": "deleted" }

Errors: 403 if the wallet is not the deployer.

Step 1: Get Quote

POST /agent/deploy
Content-Type: application/json

{
  "uniqueName": "my-app",
  "displayName": "My App",
  "upload": { "type": "files", "files": [{ "path": "index.js", "content": "base64..." }] }
}

Response 402 (no credits):

{
  "error": "Payment required",
  "amount_usd": 0.5,
  "amount_token": "500000",
  "current_credit_balance_usd": 0,
  "active_projects": 0,
  "pay_to": "0x7EA5...",
  "payment_chain": "arbitrum",
  "token": "usdc",
  "decimals": 6,
  "supported_chains": [...]
}

Response 402 (has credits but active projects exist):

{
  "error": "Payment required",
  "warning": "You have 2 active project(s) sharing credits. Paying extends total runtime. To deploy using existing credits (will reduce other projects' runtime), retry with header X-Use-Existing-Credits: true",
  "amount_usd": 0.5,
  "current_credit_balance_usd": 1.20,
  "active_projects": 2,
  "pay_to": "0x7EA5...",
  ...
}

Step 2: Pay

Send ERC20 transfer with viem:

import { createWalletClient, createPublicClient, http } from "viem";
import { arbitrum } from "viem/chains";

const txHash = await walletClient.writeContract({
  address: "0xaf88d065e77c8cC2239327C5EDb3A432268e5831", // USDC on arbitrum
  abi: [
    {
      name: "transfer",
      type: "function",
      stateMutability: "nonpayable",
      inputs: [
        { name: "to", type: "address" },
        { name: "value", type: "uint256" },
      ],
      outputs: [{ name: "", type: "bool" }],
    },
  ],
  functionName: "transfer",
  args: [quote.pay_to, BigInt(quote.amount_token)],
});
await publicClient.waitForTransactionReceipt({ hash: txHash });

Step 3: Deploy

Same request body, add payment header:

POST /agent/deploy
X-Payment-Tx: 0xTransactionHash
X-Payment-Chain: arbitrum
X-Payment-Token: usdc

Response 200:

{ "projectId": "uuid", "deploymentId": "uuid", "status": "deploying" }

Step 4: Poll

GET /agent/deploy/{projectId}/{deploymentId}/status

{ "status": "deploying" } — keep polling every 5s
{ "status": "ready", "endpoint": "https://..." } — done
{ "status": "failed", "reason": "..." } — stop

Upload Types

Files: { "type": "files", "files": [{ "path": "...", "content": "base64" }] } Zip: { "type": "zip", "data": "base64-zip", "filename": "code.zip" }

Important: When uploading files, exclude build artifacts and dependencies:

node_modules/, dist/, build/, .next/
.env, .env.*, keys, secrets
.git/, .DS_Store
__pycache__/, venv/, .venv/

Only upload source code and config files needed to build and run the project.

Error Codes

Code	Meaning
400	Invalid body
401	Bad signature / expired / nonce reused
402	Payment required or verification failed
403	Wrong wallet on status endpoint
409	Tx hash already used
