## How to call it through Zero

```sh
zero fetch --capability parkland-archives-almanac-records-4a505eb4
```

Example prompt: Pull up Parkland Archives almanac records for US trade statistics from 1895 to 1905, limit to 20 results.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
