Unlock full API access
You've seen what the simulator can do. Get your API key and continue with unlimited steps, programmatic access, RL training environments, and multi-cloud analysis — no credit card required.
What you unlock with a full API key
Paste your Canvas Cloud AI key below. The World Model will verify your identity and return a permanent key scoped to this API.
Use your World Model key (cwm_live_...) in the Authorization header for every request. You now have access to simulations, chaos engineering, multi-cloud analysis, and more.
curl -X POST https://clouddigitaltwin.com/api/simulations \-H "Authorization: Bearer cwm_live_your_world_model_key" \-H "Content-Type: application/json" \-d '{"name": "My First Simulation","provider": "aws","region": "us-east-1"}'
Good to know
Your key, your scopes
World Model keys issued via Canvas Cloud AI start with read and write access. Visit the Admin Key Management page (/admin/keys) if you need admin-scoped key setup.
One Canvas Cloud AI key → many World Model keys
You can register multiple times with the same Canvas Cloud AI key to create separate keys for different projects or agents.
Email verification required
Your Canvas Cloud AI account email must be verified before you can get a World Model key. Check your Canvas Cloud AI account if you see a 403 error.
Rate limits
New keys start at 1,000 requests per hour. The limit is tied to your World Model key, not your Canvas Cloud AI key.
Credit costs
Your account starts with 1,000 free credits per month — refreshed automatically every 30 days. Status and read endpoints are always free.
| Call type | Description | Credits |
|---|---|---|
| Simulation step | Run one step of a cloud simulation | 1 |
| RL episode step | Single action in a reinforcement learning episode | 1 |
| Chaos job | Inject a failure scenario and evaluate resilience | 5 |
| Multi-cloud strategy job | Generate and score multi-cloud architecture variants | 5 |
| AI explanation | GPT-powered analysis, bottleneck insight, or optimization tip | 10 |
| Status / read endpoints | Fetch job status, metrics, or list resources | Free |
Need more? Buy a credit pack — Starter $9 / 10k, Professional $49 / 100k, Enterprise $299 / 1M. Paid credits never expire.
Pay per request — no API key needed
Agents and scripts can pay in USDC on Base via the x402 protocol — no account or API key required.
npm install x402-fetch viem
import { wrapFetchWithPayment } from "x402-fetch";import { createWalletClient, http } from "viem";import { base } from "viem/chains";import { privateKeyToAccount } from "viem/accounts";const account = privateKeyToAccount(process.env.AGENT_WALLET_PRIVATE_KEY as `0x${string}`);const walletClient = createWalletClient({ account, chain: base, transport: http() });// Wrap fetch once — every 402 response is paid and retried automatically.const fetch402 = wrapFetchWithPayment(fetch, walletClient);const res = await fetch402("https://www.cloudworldmodel.ai/api/simulations/sim_abc/step-hybrid",{ method: "POST", body: JSON.stringify({ steps: 1 }) });const { metrics, settlement } = await res.json();// metrics.cpuUsage, metrics.costPerHour, settlement.transactionHash
Python, Go, and cURL examples — plus wallet setup, per-call pricing, and replay-protection details — are in the Pay-per-request section on the Agents page.
Frequently asked questions
Verify Simulation Accuracy
Before you build on the numbers, see how they hold up. The benchmark report runs the simulation engine head-to-head across AWS, GCP, Azure, and OCI — comparing cost accuracy, latency profiles, throughput, and error-rate behavior. Every result is reproducible and re-validated in CI.
