How this service works
Instant weather data by city name — no API keys, no geocoding setup, no rate limits. Current conditions and daily forecasts for any city worldwide in structured JSON, ready for agent consumption.
Output
A JSON object containing the resolved city name, country, latitude/longitude, and an array of daily forecast objects — each with date, human-readable condition label, max and min temperature in Celsius, weather code, peak wind speed in km/h, precipitation in mm, and precipitation probability percentage.
Example use cases
Trip planning with packing advice
“I'm flying to Barcelona next week. What's the weather going to be like for my 7-day stay? I need to know daily temperatures, rain chances, and wind conditions so I can pack the right clothes.”
Event scheduling across multiple cities
“We're planning a outdoor company picnic and need to pick the best day next week. Check the 5-day forecast for Chicago, Denver, and Austin — show me which city will have the best weather without rain and with calm winds.”
Agricultural harvest timing decision
“Tell me the weather outlook for the next 4 days in the Napa Valley area. I need to know daily highs, lows, precipitation amounts, and wind speeds to decide when it's safe to harvest.”
Technical details
Endpoint
GEThttps://weather.hugen.tokyo/weather/forecast?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured multi-day daily weather forecast (up to 7 days) by city name and do not want to handle geocoding or API key setup. Prefer this over real-time/current-conditions endpoints when planning ahead, and over coordinate-based APIs when only a city name is available. Ideal for travel planning, scheduling, or workflow automation requiring structured JSON weather data.
Side effects
- Unknown or misspelled city name returns an error or empty result
- Days value outside 1–7 range may return an error or be clamped
- Network timeout if geocoding or upstream weather service is slow
- Payment failure (402) if USDC payment is not provided or insufficient
- City name ambiguity (e.g. 'Springfield') may resolve to an unexpected location
