Nationalize Name — Country of Origin Predictor

Use this endpoint when you need a probabilistic breakdown of which countries a first name most likely originates from — ideal for demographic enrichment, lead qualification, audience segmentation, or cultural analysis. Prefer this over general name-lookup APIs when ranked probabilities per country are required rather than simple ethnicity labels.

• Unknown or very rare name may return an empty country list or zero-probability results
• Missing or empty 'name' parameter returns an error or empty response
• Non-alphabetic characters or numeric names may yield no results
• Network timeout or service unavailability returns HTTP 5xx
• Insufficient USDC balance causes payment failure via x402 protocol
