Imprint Check

by German Imprint Check (DDG) in Email & messaging

x402 APIPassing, checked 3 h ago

Conditional duties the HTML cannot decide come back as unknown, never as a defect. Finding with citation, not legal advice.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.1.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
