How this service works
Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.
Output
A JSON object containing economic and demographic comparison data for two countries (keyed as 'a' and 'b' by ISO code), plus a 'comparison' object summarizing key differences and metrics between them.
Example use cases
Investment market research comparison
“I'm considering expanding into either Brazil or Germany — can you pull a side-by-side economic comparison of the two countries so I can see their GDP, population, and other key indicators?”
Academic country benchmarking
“For my research paper I need to compare the economic profiles of India and South Korea — can you get me a structured comparison of their main stats?”
Trade partner economic analysis
“We're evaluating new trade partners — compare the economic and demographic data of Mexico and Vietnam for me so I can see which market looks stronger.”
