Claim twitter.use.x402atlas.com

Two proofs, no account: a signature from your payTo wallet, and a token on your domain. Then agents that use the pay guard see that wallet as verified by you, and you can switch on free alerts.

1. Put this on your domain (one of the two):

2. Sign this exact message with the wallet:

Or by API

curl -X POST https://factline.dev/v1/x402/claim/start -H 'content-type: application/json' \
  -d '{"origin":"twitter.use.x402atlas.com","wallet":"0x...","email":"you@example.com"}'
# put the token on your domain, sign the message, then:
curl -X POST https://factline.dev/v1/x402/claim/verify -H 'content-type: application/json' \
  -d '{"origin":"twitter.use.x402atlas.com","wallet":"0x...","signature":"0x..."}'

We store the domain, wallet, token, optional email and webhook, and the dates. Revoke any time with a signature: POST /v1/x402/claim/revoke.
