## When to prefer this

Use this endpoint when you need a quick, pay-per-call age prediction without managing your own ML infrastructure. Best suited for lightweight demographic enrichment tasks where you need a probabilistic age estimate from a name or profile data, and you're already operating within the x402 payment ecosystem on Base chain.

## Known failure modes

- Missing or malformed input data returns an error
- Empty name or invalid input schema causes a 400-level error
- Payment failure via x402 protocol results in 402 Payment Required
- Model uncertainty may return low-confidence or null age estimates
- Rate limiting or server errors return 5xx responses
