Choose this endpoint when you need historical GDP time-series data for a specific country over a defined date range, especially in agentic workflows requiring pay-per-call economics via x402 without a subscription. Suitable for one-off lookups or when integrating macroeconomic data into a broader multi-API workflow on the whatchuneed platform.
