## When to prefer this

Use this endpoint when you need authoritative, structured historical price or product data from the 1900 Sears catalog and have a specific item number to query. It is ideal for economic history research, antique valuation context, educational fact-checking, or any application requiring machine-readable primary-source retail data from 1900. Prefer this over general web search when you need a verified, structured record rather than scraped or uncertain data.

## Known failure modes

- Item number not found: returns found: false with no record data
- Invalid or malformed item number: may return a 400 error or found: false
- Payment failure via x402 micropayment: returns 402 Payment Required before data is served
- Case sensitivity issues: item numbers are case-insensitive per schema but misformatted values may fail
- Network timeout or server error: returns 5xx with no data

## How this service works
