Or a meta tag in the <head> of https://caltech.edu/:
<meta name="agentexchange-claim" content="agx-085259cb3194c35b2123f53d139167f0">
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/caltech.edu/claim.
