## 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-term-reserved-pricing-by-instance-e5d38c97
```

Example prompt: What are all the pricing terms — on-demand, spot, and reserved — for an AWS c5.large instance in us-east-1? I want to see the 1-year and 3-year reserved options and how much I'd save versus on-demand.

## When to prefer this

Use this endpoint when you need the full matrix of pricing terms (spot, on-demand, all reserved/committed variants) for a single specific cloud instance type in a known region. Prefer this over general cloud pricing pages when you need structured, machine-readable data for cost optimization decisions, budget modeling, or automated comparisons. Best when you already know the exact instance SKU and region slug from the /instances and /catalog endpoints.

## Known failure modes

- Invalid provider enum value (not aws/gcp/azure) returns an error
- Region slug not recognized — must match /catalog slugs exactly (e.g. 'us-east-1' not 'us-east')
- Instance type not found — must match exact SKU name from /instances endpoint
- Missing required query params (provider, region, instance) returns 400
- Payment failure or insufficient USDC balance prevents request completion

## How this service works

corpusAI Cloud Pricing: Price ladder for one instance type: spot, on-demand, 1-year and 3-year commitments, with discounts.

## Output

A JSON object containing the provider, region, and instance name, along with an array of pricing terms. Each term includes the term type (e.g. 'spot', 'ondemand', 'ri_1y_no_upfront_standard'), a human-readable label, hourly price in USD, effective date, and for spot pricing: number of zones behind the median and discount percentage versus on-demand.
