# corpusAI Cloud Pricing: Spot Price Snapshot

> corpusAI Cloud Pricing: Spot Price Snapshot is a paid API for AI agents from cloud.trycorpus.ai, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-11).

Returns the current spot/on-demand instance prices for all products in a given cloud provider region, with timestamps indicating when each price took effect.

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-pricing-spot-price-snapshot-562a7f93
```

Example prompt: What are the current spot instance prices for AWS in us-east-1? I want to see all the instance types and their USD-per-hour rates right now.

## When to prefer this

Use this endpoint when you need a real-time snapshot of all current spot/on-demand instance prices for a specific cloud provider region (AWS, GCP, or Azure). It is ideal for cost optimization agents, FinOps dashboards, autoscalers, and infra provisioning tools that need up-to-date per-instance pricing with timestamps. Prefer this over scraping cloud provider pricing pages or using stale static price lists. Best when you already know the provider and region and want a full set of prices in one call.

## Known failure modes

- Missing or invalid 'provider' query param returns an error (must be one of aws, gcp, azure)
- Missing or invalid 'region' slug returns an error — region must match the provider's catalog format (e.g. us-east-1 for AWS, not 'us-east')
- Payment of 0.1 USDC via x402 not included or fails — request is rejected with 402 Payment Required
- Region has no current pricing data — may return empty prices array
- Network timeout or service unavailability — no snapshot returned

## How this service works

corpusAI Cloud Pricing: Current price of every instance type, zone and product in a whole region, in one call.

## Output

A JSON object containing the provider name, region, a timestamp of the newest pricing event ('as_of'), a count of price entries, and an array of price records each with instance type, product name, availability zone, USD-per-hour price, the datetime the price took effect, and how many seconds ago that was.
