How this service works
Before your agent plans a multi-day operation — logistics, construction, an event, crop work: a day-by-day forecast for any GPS point or city, with daily minimum and maximum 2 m temperature, total precipitation and peak 10 m wind per UTC calendar day, from today to the end of the NOAA GFS window (~16 days), extendable to 35 days on the NOAA GEFS ensemble mean — those extra days are an average of ~30 members, so their extremes are smoothed: trend, not threshold triggers. Each day names the model that served it and carries a coverage flag.
Output
A JSON response containing one entry per UTC calendar day from today out to the end of the GFS window (~16 days), each with daily minimum and maximum 2m temperature, total precipitation (reconstructed from GFS accumulation buckets), and maximum 10m wind speed. Partial days at window edges are flagged with coverage.complete=false rather than omitted. If a city name was provided, the resolved coordinates and canonical location name are echoed back in data.location.
Example use cases
Multi-day outdoor event planning
“I'm organizing a 5-day music festival in Austin, Texas starting next Friday — can you pull the day-by-day forecast for the full run so I can see expected highs and lows, any rain, and peak wind speeds to plan for tents and staging?”
Construction site weather window
“We're pouring concrete at a site near Denver, Colorado next week and need at least three dry days in a row with temps above freezing — can you get me the 16-day daily forecast so we can pick the best window?”
Crop harvest timing forecast
“I need to decide when to start the wheat harvest on our farm just outside Toulouse, France — can you give me the daily precipitation and temperature forecast for the next two weeks so I can avoid rain days?”

Endpoint
GEThttps://api.invoket.com/weather/forecast/dailyWhen to prefer
Use this endpoint when you need a multi-day (up to ~16 days) daily weather forecast with no API key or account setup, and you are comfortable paying $0.01 USDC per call via x402. Ideal for agents that need daily granularity (min/max temp, precipitation, wind) from the GFS model without subscribing to a weather service. Prefer over alternatives when you want city-name-based resolution without pre-geocoding, or when per-call stablecoin payment is the desired billing model.
Side effects
- City name not found in GeoNames gazetteer — ambiguous or misspelled city name returns an error or empty result
- Missing required location parameters (no lat/lon and no city) — returns a 400-level error
- GFS model data temporarily unavailable — may return a 503 or partial data
- x402 payment not settled or insufficient USDC balance — request rejected before processing
- Country ISO code invalid or mismatched — may affect city resolution accuracy
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| latrequired | string | |
| lonrequired | string | |
| daysrequired | string | Number of UTC calendar days to return, 1-35, starting today. Defaults to 16 — the deterministic GFS window; ask for more explicitly to reach the GEFS ensemble-mean tail, whose smoothed extremes answer trend questions rather than threshold triggers. Alternative to lat+lon: pass city=<name> (alias location=, optional country= ISO 3166 alpha-2) resolved via the embedded GeoNames gazetteer and echoed back as data.location. |
