Claim the scorecard for chessdatabase.science

Free, no account, no email. Prove you control chessdatabase.science 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 · F". A claim does not change the score.

1. Your token for chessdatabase.science

2. Publish it, either way

A file. Serve the token as plain text at https://chessdatabase.science/.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-7b4ff1591ea42be165cb108190b485e8

Or a meta tag in the <head> of https://chessdatabase.science/:

<meta name="agentexchange-claim" content="agx-7b4ff1591ea42be165cb108190b485e8">

3. Verify

We fetch the file, then the home page, once, with the user agent agentexchange-grade-claim/1.0 and a 7-second timeout.

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/chessdatabase.science/claim.
