## When to prefer this

Choose this endpoint when you need real-time current weather conditions for a US location identified by ZIP code. It is backed by the authoritative US National Weather Service, has no rate-limit pressure for commercial use, and costs only $0.0012 USDC per call. Prefer it over general weather APIs when you want public-domain government data for US locations and need to keep per-call costs predictable.

## Known failure modes

- Invalid or non-existent ZIP code returns an error (zip must be exactly 5 digits)
- ZIP code exists but is not covered by a NWS observation station (rare rural codes may return no data)
- National Weather Service upstream API temporarily unavailable causing a 5xx or timeout
- Malformed zip parameter (wrong format, letters included) causes a 400-level validation error
