Claim the scorecard for blockchain-api.x402-chain-tools.workers.dev

Free, no account, no email. Prove you control blockchain-api.x402-chain-tools.workers.dev 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 · C". A claim does not change the score.

1. Your token for blockchain-api.x402-chain-tools.workers.dev

agx-18bc2a905901f5a71d6f14afcd633da7

2. Publish it, either way

A file. Serve the token as plain text at https://blockchain-api.x402-chain-tools.workers.dev/.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.

Or a meta tag in the <head> of https://blockchain-api.x402-chain-tools.workers.dev/:

<meta name="agentexchange-claim" content="agx-18bc2a905901f5a71d6f14afcd633da7">

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/blockchain-api.x402-chain-tools.workers.dev/claim.
