Multi-Day City Weather Forecast (Open-Meteo)

Choose this endpoint when you need a simple multi-day daily min/max temperature forecast for a city identified by name rather than coordinates, and do not need hourly granularity or specialized derived indices. It is ideal for travel planning, event scheduling, and general daily planning use cases. Prefer sibling endpoints for specialized outputs like HVAC demand, construction risk, UV exposure, or air quality.

• City name not recognized or ambiguous — may return an error or default to a mismatched location
• Days parameter out of supported range — Open-Meteo typically supports up to 16 days; exceeding this may return an error or truncated data
• Missing required 'city' parameter — returns a validation error
• Network or upstream Open-Meteo service unavailability — returns a 5xx error
• Rate limiting or payment failure via x402 — returns a 402 Payment Required
