Sage Console | Decisions you can act on

HTTP	Meaning
`400`	Invalid request (schema validation, or a per-kind limit violation)
`401`	Missing or invalid API key (see Authentication)
`402`	Valid API key, but account balance too low
`503`	Service loading or temporarily unavailable

Invalid requests return a standard schema message, for example:

{"detail": "content: Field required"}

{"detail": "scale levels must be integers in 0..4 (model trained on 5 levels); got [9]"}

{"detail": "Service is still loading."}

{"detail": "API key required. Provide a valid Levanto API key."}
