# Cloud World Model – Simulation Explain

> Cloud World Model – Simulation Explain is a paid API for AI agents from www.cloudworldmodel.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns a plain-language or technical explanation of what is currently happening in a running cloud infrastructure simulation

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-simulation-explain-21711ae7 -d '<json body>'
```

Example prompt: I'm running a cloud simulation on Cloud World Model and I'm not sure what's going on — can you explain the current state of simulation abc-123 in simple, beginner-friendly terms so I can understand what's happening with my cluster?

## When to prefer this

Use this endpoint when a user or agent needs to understand the current state or behaviour of an already-running cloud simulation rather than starting or modifying one. It is ideal for educational contexts (Canvas Cloud AI learners), post-incident review of simulation runs, and agent-driven diagnosis loops where the agent needs to read back what the simulation is experiencing before deciding next steps.

## Known failure modes

- simulationId not found or expired — 404 with unknown simulation error
- simulationId path variable missing or malformed — 400 bad request
- simulation not yet in a state that can be explained (still initializing) — may return empty or pending explanation
- service unavailable if simulation backend is down — 503
- payment not attached or insufficient — 402 Payment Required

## 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 natural-language explanation string describing the current state of the simulation, including metrics, root causes, and system behavior (e.g. CPU utilization percentage, RPS, autoscaler threshold status). In beginner mode the explanation avoids jargon; in standard mode it is technical.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "beginnerMode": {
   "type": "boolean",
   "description": "Return a simplified, jargon-free explanation"
  }
 }
}
```

## Response schema (JSON Schema)

```json
{
 "type": "json",
 "example": {
  "explanation": "Your simulation is experiencing high CPU utilization (82%) because the traffic load of 8 000 RPS exceeds the capacity of the current 3-node cluster. The autoscaler has not yet triggered because CPU has not been above the 75% threshold for the required 2-step cooldown window."
 }
}
