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 paginated JSON response containing matching historical records, each with: a record name, the year the statistic refers to, a numeric value, its unit (e.g. USD, persons), category, source page number, source document identifier, an uncertainty flag, and a flag reason if applicable. Also includes total count, limit, and offset for pagination.
Example use cases

“Can you look up US merchandise export figures from the Parkland Archives almanac for the year 1899? I want the actual dollar values from the primary source.”

Find early 1900s postal rate data
“I need historical postal rate data from around 1900. Can you query Parkland Archives for postal_rates records and show me the first 25?”
Technical details
Endpoint
GEThttps://history.parklandarchives.com/api/almanac-recordsWhen to prefer
Choose this endpoint when you need structured, citation-ready historical statistics from verified primary sources (World Almanac circa 1900, Sears catalog prices), especially when you need to filter by specific year ranges or categories like trade, elections, population, finance, postal rates, or military. Prefer this over general web search when you need reliable, structured numeric data with provenance (source page and document identifier) rather than unverified narrative content.
Side effects
- No records found for very narrow year/category/search combinations — returns empty records array with total:0
- Invalid or out-of-range year values may return validation errors
- Exceeding limit maximum of 200 returns an error
- Payment failure via x402 micropayment prevents access to data
- Network timeout if the archive database is under load
