## 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-history-export-55a614d0
```

Example prompt: Pull the full historical spot price history for AWS in us-east-1 from corpusAI Cloud Pricing so I can analyze how compute costs have trended since 2014.

## When to prefer this

Choose this endpoint when you need historical time-series spot pricing data for major cloud providers (AWS, GCP, Azure) going back to 2014, particularly for cost trend analysis, budget forecasting, or region cost comparison. Prefer this over current-price APIs when the use case requires longitudinal pricing data or historical context.

## Known failure modes

- Missing required 'provider' or 'region' query parameters returns an error
- Invalid provider value (not aws/gcp/azure) causes rejection
- Region slug not matching provider's catalog format returns error or empty result
- Payment of $3 USDC via x402 not completed results in 402 response
- Region has no historical spot data available returns empty dataset

## How this service works

corpusAI Cloud Pricing: Legacy daily and monthly history of every type in a region as one gzip TSV file.

## Output

A JSON export of historical spot instance pricing records for the specified cloud provider and region, including time-series price data potentially going back to 2014, suitable for trend analysis, cost modeling, and infrastructure budgeting.
