x402 APIPassing, checked 1 h ago

Current conditions for any point on Earth, taken from the Norwegian Meteorological Institute's official forecast model rather than a commercial aggregator. Returns temperature, humidity, pressure, wind speed and bearing, cloud cover and the next hour's precipitation, plus the exact model run it came from and the units the institute itself declares, so the figure can be cited and checked instead of merely trusted.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://flat-rate-llm.kikoribera03.workers.dev/v1/weather/now?lat=40.4165&lon=-3.7026'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://flat-rate-llm.kikoribera03.workers.dev/v1/weather/now?lat=40.4165&lon=-3.7026' \
