How this service works
Use when an agent needs a weather forecast for a latitude/longitude: current conditions plus up to 7 local-day summaries (min/max temperature, precipitation, max wind, weather symbol) in the local time zone. Data from MET Norway (CC BY 4.0). $0.01 USDC on Base; charged only on 2xx, never for invalid input.
Output
Returns current weather conditions and a per-day summary for each requested day, including minimum and maximum temperature, precipitation amount, maximum wind speed, and a weather symbol code — all expressed in the location's local time zone.
Example use cases
Outdoor event weather check
“I'm planning an outdoor concert at latitude 51.5074, longitude -0.1278 — can you pull the 7-day weather forecast so I know what conditions to expect, including rain and wind?”
Travel packing forecast
“We're flying into Reykjavik — coordinates 64.1355, -21.8954 — in 3 days. Can you get me the daily temperature highs and lows plus precipitation for the next 4 days so we know what to pack?”
Logistics route condition check
“Before we dispatch the delivery truck, can you check the weather forecast for the next 2 days at lat 45.4642, lon 9.19 — specifically wind speed and any precipitation that might affect the route?”

Endpoint
POSThttps://api.facts402.com/weather?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need point-location weather forecasts (current + multi-day summaries) for any global coordinate, especially for travel, tourism, logistics, or event planning agents. It is particularly well-suited when you have precise lat/lon coordinates and need structured daily summaries (temp range, precipitation, wind) rather than raw hourly data. Backed by MET Norway's high-quality open data, it is a reliable choice for European and global coverage without requiring a proprietary weather API key.
Side effects
- Latitude or longitude out of valid range (-90 to 90 / -180 to 180) returns a validation error
- Days parameter outside 1-7 range returns a validation error
- MET Norway upstream service unavailable may result in a timeout or 502 error
- Coordinates over open ocean or polar extremes may return incomplete or missing data
- Payment failure (insufficient USDC balance) returns 402 Payment Required
