## When to prefer this

Choose this endpoint when you need a quick, pay-per-call gender prediction from a first name without managing your own ML model. It is well-suited for one-off enrichment tasks, ad hoc lookups, or when you want to avoid the overhead of a subscription-based demographics API. Prefer alternatives if you need bulk batch processing at lower per-unit cost or if you require extremely high accuracy for culturally diverse or non-Western names.

## Known failure modes

- Empty or missing name input returns an error or null result
- Highly ambiguous or gender-neutral names may return low-confidence predictions
- Non-Latin or culturally rare names may produce inaccurate results
- Malformed request body causes a 400-level error
- Payment failure on Base chain results in a 402 response blocking the call
