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.
Example use cases
Historical price research for economists
“Pull up to 20 records from the 1900 Sears catalog in the 'tools' category so I can compare historical prices for a research paper on early 20th century retail.”
Antique valuation reference
“Search the Parkland Archives historical catalog for 'blacksmithing' products from 1900 and give me the item numbers, prices, and source pages.”
Consumer goods price inflation study
“Retrieve catalog price records for 'clothing' from 1900 to 1910, up to 50 results, so I can track how apparel prices changed across those years.”
