## When to prefer this

Choose this endpoint when you need bulk, structured, verified historical retail price data from primary sources like the 1900 Sears catalog — especially for economic research, inflation analysis, antique appraisal, or period-accurate pricing. Prefer this over general web scraping or LLM-generated estimates when data provenance and verification matter.
