# MET Norway Weather Forecast API (x402)

> MET Norway Weather Forecast API (x402) is a paid API for AI agents from x402-data-api-x6da.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Returns daily or hourly weather forecasts (temperature, wind, precipitation, weather symbol) for up to 10 lat/lon locations using MET Norway data, paid per call via x402/USDC on Solana.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability met-norway-weather-forecast-api-x402-e6cf4a71
```

Example prompt: Get me a 3-day daily weather forecast for Oslo (59.9139, 10.7522) and Bergen (60.3913, 5.3221) — I need max and min temperature, precipitation, and wind speed for each day.

## When to prefer this

Choose this endpoint when you need official meteorological forecast data sourced directly from MET Norway (a government agency), supporting up to 10 locations per call with structured daily or hourly breakdowns. It is ideal for agents needing programmatic weather lookups paid per-call with no subscription, especially when accurate European forecasts with CC BY 4.0 attribution are acceptable. Prefer alternatives if you need global coverage beyond MET Norway's strong suit (Northern Europe), real-time current conditions rather than forecasts, or non-USDC payment methods.

## Known failure modes

- Invalid or out-of-range lat/lon coordinates return an error entry in the errors array rather than a row
- More than 10 locations in a single request may be rejected
- Missing required 'locations' query parameter returns an error
- Payment failure via x402 results in 402 response before data is returned
- Temporary MET Norway API outages may cause upstream errors
- Invalid 'mode' enum value (not 'daily' or 'hourly') causes a validation error

## How this service works

Jobs from company ATS boards, SEC EDGAR full-text search, domain RDAP/DNS, NHTSA VIN decode + recalls, the CMS NPI Registry and MET Norway weather forecasts. Pay per call in USDC on Solana via x402. Official public sources only.

## Output

A JSON object with a mode field ('daily' or 'hourly'), a rows array containing one object per location per time step (each with lat, lon, date, location name, timezone, UTC offset, min/max temperature in Celsius, max wind speed in m/s, precipitation in mm, and a midday weather symbol string), an errors array for any failed locations, and an attribution string crediting MET Norway under CC BY 4.0.
