Is this your API?

Claim this page with one signature from your payTo wallet and a token on factline.dev. Free, no account. You get an email when your 402 stops answering, when a catalogue lists a wallet for your domain that you did not sign, or when a lookalike domain shows up, and agents using the pay guard see your wallet as verified by you.
