Verify your partner page before submitting. Our Contextual DOM & Two-Page Sample Inspector checks single-page citation links inside <main>/<article>, rejects <footer>/<nav> placement, and samples up to one reachable internal page when linked.
Claiming or correcting an existing profile ($0 Free): Verify domain control via /.well-known/agentindex-claim.txt or your bound maintainer credential — no backlink/citation required. Optional Citation Upgrade: Provide a single-page contextual citation link inside <main>/<article> to activate rel="dofollow". Public backlinks or payment credits alone never grant edit ownership.

/.well-known/agentindex-claim.txt challenge (or your bound requester_secret) to claim your profile and edit name, tagline, description, category, pricing, and /llms.txt URL for $0.<main>/<article> on a single page of your domain to activate the Verified Citation badge and rel="dofollow".Sponsored card in the Homepage & Category Featured Spotlight, a Sponsored badge on /tool/:slug, and priority ordering in /llms-full.txt and /feed.xml.rel="sponsored nofollow". Paid placement never grants dofollow and never guarantees search rankings, AI citations, or traffic volume.Yes. Click Claim Official Profile on your tool card, generate a single-use /.well-known/agentindex-claim.txt challenge in the Founder Workbench, host the proof line on your canonical HTTPS origin, and submit with backlink_url left blank. Your profile is immediately marked domain_control_verified and updated for free.
When you complete a /.well-known/agentindex-claim.txt challenge, your private requester_secret (stored only as a SHA-256 hash on the server) is atomically bound to your listing, root domain, and canonical HTTPS origin. You can use that requester_secret for future profile edits or invoice creation.
After verifying domain control, create an owner-bound invoice in the Sponsored Spotlight tab, transfer 49 USDT via BEP-20 (BNB Smart Chain) or TRC-20 (Tron), and submit your transaction hash. Our Worker verifies the on-chain receipt directly via RPC, activates your 30-day sponsored_profile_grants window immediately, and applies rel="sponsored nofollow".
No. Public backlinks and transaction hashes never grant maintainer authority. Both profile edits and sponsored invoices require cryptographic domain-control proof for that exact listing, root domain, and canonical HTTPS origin.
