## When to prefer this

Use this endpoint when you need a ready-made, up-to-date, globally comprehensive GNI-PPP-USD dataset in one call, without having to query the World Bank API directly, handle pagination, or process raw CSV/XML. Ideal for dashboards, economic comparisons, or enriching country-level datasets with income data.

## Known failure modes

- Payment failure: x402 payment of $0.02 USDC not processed — endpoint returns 402 Payment Required
- Data unavailability: upstream World Bank data not yet refreshed for a given country — that country entry may be missing or null
- Service downtime: clonecho.builda.company is unreachable — returns 5xx or no response
- Invalid request: unexpected query parameters may be ignored silently or cause errors
