# Cloud World Model Right-Sizing Hint

> Cloud World Model Right-Sizing Hint 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 right-sizing recommendations for over-provisioned nodes in a cloud simulation, including estimated cost savings percentages.

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-right-sizing-hint-4108e62d
```

Example prompt: Check simulation e6c6e6f7-3893-4a1c-bb37-e49558245a04 and tell me which nodes are over-provisioned and how much I could save by right-sizing them.

## When to prefer this

Use this endpoint when you need actionable cost-reduction recommendations for a running cloud simulation on cloudworldmodel.ai, specifically to identify over-provisioned nodes and quantify savings. Prefer this over the autoscaling threshold endpoint when the goal is cost optimization rather than scaling policy tuning.

## Known failure modes

- Simulation ID not found or expired — returns 404
- Simulation not in a valid state to generate hints — returns 400 or empty hints array
- Authentication or payment failure — returns 402 or 401
- Simulation has no over-provisioned nodes — returns empty hints array

## How this service works

Get right-sizing recommendations for over-provisioned nodes with estimated savings percentages.

## Output

Returns an array of right-sizing hints for over-provisioned nodes in the specified simulation, each including recommended instance size changes and estimated cost savings percentages.
