Claim the scorecard for isotopes.gov

Free, no account, no email. Prove you control isotopes.gov 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 isotopes.gov

agx-6a5801ff2ee5deba3cb4dd56ca3a5bbb

2. Publish it, either way

A file. Serve the token as plain text at https://isotopes.gov/.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-6a5801ff2ee5deba3cb4dd56ca3a5bbb

Or a meta tag in the <head> of https://isotopes.gov/:

<meta name="agentexchange-claim" content="agx-6a5801ff2ee5deba3cb4dd56ca3a5bbb">

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/isotopes.gov/claim.
