# dimfact Cheapest Cloud Compute Finder

> dimfact Cheapest Cloud Compute Finder is a paid API for AI agents from dimfact.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Returns the cheapest on-demand cloud instance across AWS, Azure, and GCP that meets a given vCPU and memory specification, with per-provider breakdown.

## 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 dimfact-cheapest-cloud-compute-finder-e2265f3e -d '<json body>'
```

Example prompt: What's the cheapest on-demand cloud VM I can get with at least 4 vCPUs and 16GB of RAM running Linux — show me the winner and the best option from each provider?

## When to prefer this

Use this endpoint when an agent or user needs to find the lowest-cost on-demand cloud VM across AWS, Azure, and GCP without managing API keys or signing up for any service. It is ideal for cost-optimization workflows, pre-deployment infrastructure decisions, multi-cloud price comparisons, and budget-constrained compute selection. Prefer this over manually querying each cloud provider's pricing APIs when you want a unified, pay-per-call answer with no setup friction.

## Known failure modes

- No instances match the requested vCPU/memory spec — 'cheapest' returns null and 'by_provider' is empty
- Invalid region slug or provider name causes no results or validation error
- Spec too aggressive (very high vCPU or memory) with no matches in the dataset
- Payment not completed via x402 or MPP results in 402 Payment Required response
- Malformed request body missing required 'vcpu' or 'memory_gb' fields returns a 400 error

## How this service works

Pay-per-call data for AI agents. No API key, no signup. Starting with cloud compute pricing across AWS, Azure, GCP. Pay via x402 or MPP.

## Output

Returns a 'target' object echoing the matched spec, a 'cheapest' object with the single overall cheapest instance (provider, instance type, region slug, provider-native region code, vCPU count, memory GB, OS, and on-demand price per hour in USD), and a 'by_provider' array with the cheapest matching instance from each of up to three providers sorted ascending by price. Returns null for 'cheapest' if no instance meets the spec.
