## When to prefer this

Use this endpoint when you need a quick, pay-per-call gender inference from a first name without requiring a subscription, especially in workflows involving contact personalization, salutation generation, or demographic enrichment where a lightweight probabilistic guess is sufficient.

## Known failure modes

- Missing or empty name field returns validation error
- Ambiguous or rare names may return low confidence or unknown gender
- Non-name strings may produce nonsensical results
- Payment failure on Base chain results in 402 response before prediction is attempted
- Network timeout on Vercel-hosted endpoint
