## How to call it through Zero

```sh
zero fetch --capability parkland-archives-historical-catalog-prices-b2aa380a
```

Example prompt: Search the Parkland Archives 1900 catalog for books and return the first 10 results with their prices and materials.

## When to prefer this

Choose this endpoint when you need structured, verified historical retail price data from primary source catalogs (e.g. 1900 Sears) with rich metadata like source page, item number, and materials. It is ideal for economic research, antique valuation, inflation studies, and any use case requiring queryable, paginated access to verified archival pricing data rather than scraped or estimated figures.

## Known failure modes

- No records found for the specified year or category — returns empty records array with total: 0
- Invalid year integer format — schema validation error
- limit exceeds maximum of 200 — validation rejection
- Payment not processed via x402 — 402 Payment Required response
- Network or service unavailability — 5xx error

## How this service works

Structured historical data from verified primary sources — 1900 Sears catalog prices, World Almanac statistics, and more. Queryable by AI agents via x402 micropayments on Base.

## Output

A JSON object containing total record count, pagination info (limit, offset), and an array of matching catalog records — each with product name, USD price, category, materials, item number, source page, catalog year, catalog season, source identifier, and uncertainty/flag fields.
