Claim the scorecard for zksync.io

Free, no account, no email. Prove you control zksync.io 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 zksync.io

agx-03dbf4a0b2bf2d197fab6d4a34c09d10

2. Publish it, either way

A file. Serve the token as plain text at https://zksync.io/.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-03dbf4a0b2bf2d197fab6d4a34c09d10

Or a meta tag in the <head> of https://zksync.io/:

<meta name="agentexchange-claim" content="agx-03dbf4a0b2bf2d197fab6d4a34c09d10">

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/zksync.io/claim.
