## When to prefer this

Choose this endpoint when you need a quick, no-signup elevation lookup for a specific coordinate, billed per-call via USDC on Base through x402. Ideal for AI agents that need geospatial elevation data without managing API keys or subscriptions — particularly useful in autonomous workflows where micropayment-based access is preferred over credential management.

## Known failure modes

- Missing or invalid coordinates return an error or empty result
- Coordinates outside supported geographic coverage may return null elevation
- Malformed schema parameter may cause a 400 error
- Payment failure via x402 results in a 402 Payment Required response blocking the call
- Rate or quota issues on the underlying elevation data source may cause transient failures
