## 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-reserved-instance-snapshot-by-region-e9cd972b
```

Example prompt: Can you pull the current reserved instance pricing snapshot for AWS in us-east-1 from corpusAI's cloud pricing API?

## When to prefer this

Choose this endpoint when you need structured, machine-readable historical reserved instance pricing for AWS, GCP, or Azure by region — especially for FinOps analysis, infrastructure cost modeling, or multi-cloud cost comparisons going back to 2014. Prefer this over scraping cloud provider pricing pages directly, as it provides clean, normalized historical data in a consistent format across all three major clouds.

## Known failure modes

- Missing or invalid region slug returns an error — region must match provider format (e.g. us-east-1 for AWS, us-central1 for GCP, us-east for Azure)
- Invalid provider enum value (anything other than aws, azure, gcp) returns a validation error
- Payment of 0.1 USDC via x402 required; missing or failed payment returns HTTP 402
- No data available for very new or unsupported regions returns an empty prices array
- Rate limiting or upstream data unavailability may cause transient 5xx errors

## How this service works

corpusAI Cloud Pricing: Current reserved effective hourly price of every instance type and ri_type in a region (AWS or Azure).

## Output

A JSON object containing the provider name, region slug, a count of price records, and an array of reserved instance price entries — each with the instance type, RI type, price per hour, and the date since which that price has been in effect. May also include a note field with contextual information.
