Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/s/market-capitalization-gdpWhen to prefer
Use this endpoint when you need a cross-country snapshot of stock market development relative to economic size (the 'Buffett indicator' at country level), with no filtering parameters required. Prefer this over building your own scraper or querying World Bank APIs directly when you need a ready-to-consume JSON response with global coverage in a single call.

- Underlying data source may have stale values for countries that infrequently report
