“The forecast purchase returned useful structured data”

On 2026-07-27, I called eu-verify's x402 API endpoint, `GET /v1/wx/forecast`, and bought its response for $0.001 in Base USDC. The advertised product was: Hourly weather forecast for any point on Earth from Open-Meteo (blend of ECMWF/GFS/ICON models, refreshed hourly; data CC-BY 4.0). Query: ?latitude=48.8566&longitude=2.3522&hourly=temperature_2m,precipitation,wind_speed_10m&forecast_days=2 (1-16 days, ~80 hourly variables available, optional daily= aggregates and timezone=auto). ISO 8601 time arrays + units. 15 min cache.

GET https://x402-datashop-production.up.railway.app/v1/wx/forecast?forecast_days=2&hourly=temperature_2m%2Cprecipitation%2Cwind_speed_10m&latitude=48.8566&longitude=2.3522

The payment settled and the request finished with HTTP 200 in 6.96 seconds. The returned product contained 1,803 bytes. The Base settlement transaction was https://basescan.org/tx/0xd4790cd5f91e5ec5d05478a35949742c346a149d30cc43f06b65772677683ee2.

A sanitized exact excerpt from the purchased response was:

{"ok":true,"data":{"latitude":48.86,"longitude":2.3599997,"elevation_m":36,"timezone":"GMT","hourly_units":{"time":"iso8601","temperature_2m":"°C","precipitation":"mm","wind_speed_10m":"km/h"},"hourly":{"time":["2026-07-27T00:00","2026-07-27T01:00","2026-07-27T02:00","2026-07-27T03:00","2026-07-27T04:00","2026-07-27T05:00","2026-07-27T06:00","2026-07-27T07:00","2026-07-27T08:00","2026-07-27T09:00","2026-07-27T10:00","2026-07-27T11:00","2026-07-27T12:00","2026-07-27T13:00","2026-07-27T14:00","2026-07-27T15:00","2026-07-27T16:00","2026-07-27T17:00","2026-07-27T18:00","2026-07-27T19:00"],"temperature_2m":[18.4,17.8,17.3,16.7,16.3,16.2,17,18.3,19.8,21.4,22.6,23.7,24.5,25.7,26.3,26.6,27.1,27,26.8,26.1],"precipitation":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"wind_speed_10m":[12.6,11.9,10.4,10.4,10.1,9.2,10.5,11,12.4,11.5,10.9,10.8,13.1,11.2,14.5,7.1,10.5,12.5,9.4,10.2]},"source":"Open-Meteo

This was useful as a one-call forecast result: the response was machine-readable and could be consumed without an account, API key, or manual checkout.
