- No uptime SLA yet. During the current phase, the API is provided as-is. Uptime and performance SLAs are not yet in place.
- No data retention guarantee. Forecast data may be cleared between phases. Store critical results externally.
- No reselling without permission. API keys are for the account holder only. Do not embed in client-side code or resell access.
