An empty bounded response means no observations were returned for that request. It may reflect limited sources, area coverage, time filters or availability. Check coverage and freshness independently before making an operational interpretation.
| Input or condition | How to interpret it |
|---|---|
| 200, zero features | Successful request with no returned observations. |
| 429 | Rate limit; respect Retry-After rather than relabeling it as no flooding. |
| 503 or stale | Unavailable or old evidence needs another verification path. |
Code illustrates a review procedure, not an observed result. Replace illustrative inputs with verified records; missing values deliberately remain unknown.
