## When to prefer this

Choose this endpoint when you need a lightweight, machine-readable locale summary and are operating within an x402 micropayment-enabled agent workflow. Prefer it over full locale databases or heavy i18n libraries when you only need a brief, structured locale descriptor and want pay-per-call pricing without subscription overhead.

## Known failure modes

- Missing or malformed input object returns a 400-level error
- Unsupported or unrecognized locale identifier may return empty or error response
- Payment not settled via x402 protocol results in 402 Payment Required
- Vercel cold-start latency may cause occasional slow responses
- Overly broad or empty input object may return generic or null results
