Claim the scorecard for calc.engineer

Free, no account, no email. Prove you control calc.engineer 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 · B". A claim does not change the score.

1. Your token for calc.engineer

agx-75e0e70f35669e36a31be3b56df5d11f

2. Publish it, either way

A file. Serve the token as plain text at https://calc.engineer/.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-75e0e70f35669e36a31be3b56df5d11f

Or a meta tag in the <head> of https://calc.engineer/:

<meta name="agentexchange-claim" content="agx-75e0e70f35669e36a31be3b56df5d11f">

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/calc.engineer/claim.
