# Cloud World Model – Stateless Cloud Simulation

> Cloud World Model – Stateless Cloud Simulation is a paid API for AI agents from www.cloudworldmodel.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Run a single, bounded cloud infrastructure simulation and receive synchronous cost, performance, utilization, error, reliability, coverage, and autoscaling results without persisting any state.

## Facts

- Endpoint: GET https://www.cloudworldmodel.ai/api/simulations/stateless
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/cloud-world-model-stateless-cloud-simulation-0652a97e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_fjrGVKpls4CPueqCe_8zj

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cloud-world-model-stateless-cloud-simulation-0652a97e
```

Example prompt: Simulate what would happen to cost, performance, and autoscaling if I switch my AWS deployment from m5.xlarge to c5.2xlarge instances — give me the results without actually changing anything.

## When to prefer this

Choose this endpoint when you need a fast, stateless, one-shot cloud simulation with no side effects — ideal for pre-change impact analysis, architecture comparisons, or automated FinOps/SRE pipelines where you want synchronous multi-metric results (cost + performance + reliability) without provisioning or persisting anything. Prefer this over stateful simulation endpoints when you don't need to iterate on a saved scenario or advance through RL environment steps.

## Known failure modes

- Invalid or missing 'input' body returns a 400 validation error
- Unsupported cloud provider or resource type in the scenario body may return a 422 unprocessable entity
- Overly complex scenarios exceeding computation limits may time out or return a 503
- Malformed JSON in the request body results in a parse error
- Missing required 'type', 'method', or 'bodyType' fields cause schema validation failures

## How this service works

Simulate AWS, GCP, Azure, OCI, and DigitalOcean cloud infrastructure without provisioning real resources. Built for Canvas Cloud AI learners and agents.

## Output

A JSON object containing a simulation ID, simulation name, and a resources array, along with synchronous metrics including cost estimates, performance indicators, utilization percentages, error rates, reliability scores, coverage stats, and autoscaling fleet results — all computed without creating or modifying any real cloud infrastructure.
