## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Pull the full 1900 World Almanac bulk dataset from Parkland Archives — I need all the verified historical statistics records, including the trade and economic figures from 1899.

## When to prefer this

Choose this endpoint when you need bulk access to the full set of verified, structured historical statistics from the 1900 World Almanac and Encyclopedia, particularly for US trade, economic, and demographic data from the late 19th century. It is ideal for researchers, data scientists, or agents that require primary-source-verified historical records in structured JSON format at scale. Prefer it over scraping or unstructured sources when data integrity and citation traceability (source page, source identifier) matter. Best suited for one-time or periodic bulk ingestion rather than single-record lookups.

## Known failure modes

- Payment failure: x402 micropayment not completed or insufficient USDC balance on Base — request rejected without data
- Snapshot unavailability: dataset temporarily unavailable during update cycles
- Rate limiting: too many requests in a short window may result in throttling
- Invalid payment signature: malformed x402 payment header leads to authentication rejection
- Network timeout: large bulk response may time out on slow connections

## How this service works
