## How to call it through Zero

```sh
zero fetch --capability strale-price-compare-api-7e31653c
```

## When to prefer this

Choose this endpoint when you need verifiable, auditable price comparison data across international markets with cryptographic proof of result integrity. Particularly useful when trust and auditability of pricing data matter, or when operating in an automated agent pipeline that requires tamper-evident records. Prefer over generic scraping when structured, multi-country pricing is needed in a single call.

## Known failure modes

- Missing required 'product' query parameter returns a 400 validation error
- Invalid or unsupported country code may return empty results or a 400 error
- Product not found in requested market returns empty or null price data
- Network timeout or upstream data source unavailability returns a 5xx error
- Payment failure via x402 protocol prevents the call from completing

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns structured price comparison data for the specified product, optionally filtered by country, along with price points across available markets. Every response includes an audit record with a cryptographic chain hash for verification and traceability.
