What you can rely on

Endpoint paths, parameter names, and response shapes are stable contracts. The weather, NFL and MLB lanes are live on real data. Crypto is not a live sold lane. The retired finance primitives are not offered and answer 410 not_offered. Any breaking change is preceded by a minimum 90-day deprecation notice posted here and via the api.evioinc.com deprecation header.
