Claim the scorecard for zbmath.org
Free, no account, no email. Prove you control zbmath.org by publishing a token; you then get a private link with the grade history and a re-grade button (one per hour), and the badge reads "CLAIMED · D". A claim does not change the score.
1. Your token for zbmath.org

2. Publish it, either way
A file. Serve the token as plain text at https://zbmath.org/.well-known/agentexchange-claim.txt (HTTP 200, not redirected off the host; a www. variant is fine). One token per line if the file already carries other claims.
agx-4b3dfe0e637b522d26a9607d37ce4b59
Or a meta tag in the <head> of https://zbmath.org/:
<meta name="agentexchange-claim" content="agx-4b3dfe0e637b522d26a9607d37ce4b59">
3. Verify
Nothing is stored until the proof is found. Removing the file later does not unclaim the profile; re-verify at any time to get a fresh link. Limit: 10 verification attempts per hour per IP. Scripted use: curl -X POST https://grade.agentexchange.work/site/zbmath.org/claim.
