# corpusAI Cloud Spot Price Snapshot — All Instances

> corpusAI Cloud Spot Price Snapshot — All Instances is a paid API for AI agents from cloud.trycorpus.ai, paid per call via x402, $1/call, status unknown (last checked 2026-10-11).

Returns a full snapshot of current spot instance prices for a specified cloud provider (AWS, GCP, or Azure), including per-region and per-availability-zone pricing.

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 corpusai-cloud-spot-price-snapshot-all-instances-f1b18a5d
```

Example prompt: Pull the current spot price snapshot for all AWS instance types across every region and availability zone so I can see what everything costs right now.

## When to prefer this

Use this endpoint when you need a broad, all-at-once snapshot of spot instance pricing for an entire cloud provider (AWS, GCP, or Azure) across all regions and availability zones simultaneously. Prefer it over per-instance or per-region lookups when doing cost optimization, benchmarking, or building dashboards that require a complete market view. It is especially useful for agents doing infrastructure cost analysis, FinOps automation, or workload placement decisions where comparing many instance types at once is necessary.

## Known failure modes

- Missing or invalid 'provider' query parameter returns an error — must be exactly 'aws', 'gcp', or 'azure'
- Payment not included or insufficient USDC amount causes a 402 Payment Required response
- Rate limiting or temporary upstream data unavailability may return 5xx errors
- Stale data if upstream cloud pricing feeds have not refreshed recently

## How this service works

corpusAI Cloud Pricing: Current spot price of every type and zone in every region of a provider, in one call.

## Output

Returns a JSON object with the cloud provider name, a list of all spot instance prices (each with instance type, region, availability zone, price, and a timestamp of when that price was last observed), and a per-region summary including the number of instances tracked and the freshness timestamp.
