How this service works
Machine-to-machine macroeconomic report API. Pay per fetch in USDC over x402. No accounts, no API keys.
Output
A structured report covering 20 economies with two World Bank indicators (SP.POP.GROW and SP.URB.TOTL.IN.ZS) from 2015 to 2025. Includes key findings, a ranking table, share of group total, trend with R², volatility, a full year-by-year data matrix, and a coverage/data-quality disclosure. Available in HTML, JSON, CSV (long panel), or summary-CSV (one row per economy) formats.
Example use cases
Country-level demographic research briefing
“Give me the full population growth report as JSON so I can compare annual growth rates and urban population shares across all 20 economies over the last decade — I need the trend lines and volatility figures too.”
Spreadsheet-ready demographic data export
“Download the population growth and urbanization data as a tidy CSV panel so I can load it into my spreadsheet and compare economies side by side from 2015 through 2025.”
Executive summary of global population trends
“Get me the summary-CSV version of the population growth report — I just need the one-row-per-economy derived metrics so I can quickly see which countries are growing fastest and how urbanized they are.”
Technical details
Endpoint
GEThttps://reportbazaar.app.workbuddy.host/report/macro-population-growth?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pre-packaged, ready-to-use macroeconomic population report for 20 economies without the need for API keys or account registration. Ideal for agents that can handle x402 micropayments in USDC and need demographic trend data (growth rates, urbanization) with built-in analytics like R², volatility, and rankings — rather than raw data requiring post-processing.

- Invalid format parameter returns error (must be html, json, csv, or summary-csv)
- Upstream World Bank data unavailability may result in stale or partial data
