Inconsistent data formatting across different geographical regions caught our team completely off guard last year. One location would return clean JSON, while another would drop key index values without notice, breaking our frontend renders. My top tip is to stress-test raw API responses against edge cases early in development. We were comparing various environmental feeds and tested https://billing.meteoprog.com/air-quality-api to verify how clean their structured responses were. If I were picking a provider today, I would specifically ask how they handle alert latency during sudden weather spikes.
