Errors

HTTP	code	Description
`400`	`-255`	latitude/longitude are required without hourly.
`429`	`-316`	Daily new location (cell) limit (50) reached. Previously requested locations keep working; new locations next day (UTC). Retry-After header gives seconds until end of day.
`503`	`-256`	Cell created; Worker is filling hourly data. Retry in a minute.
`400`	`-249`	hours outside 1–168, invalid thresholds, or hourly > 168.
`400`	`-254`	hourly.time is not a valid datetime.
`401`	`-100`	x-api-key is missing, empty, malformed, inactive, banned, expired, IP-restricted, or not allowed for this API.
`429`	`-221`	Per-minute request limit exceeded. Response headers: x-rate-limit-limit, x-rate-limit-remaining, x-rate-limit-reset.
`429`	—	Package credit quota cannot cover this request. Body may be { error, limit, currentUsage, requestCost } (no code field).
`500`	`-1`	Unexpected server error. message is a generic error text without technical details.

Notes

Success body is { data: { ... } }. Error body is { code, message }. code is an ApiResponseCode enum value (negative integer).
