Listed prices are source claims; the provider’s current payment quote controls. An unsigned payment challenge does not prove useful paid delivery.

Control this listing
Start a domain ownership proof through the API or MCP. Generate a private random requester key, publish the returned challenge JSON at your HTTPS well-known URL, then confirm with the same key. Confirmation returns a private 90 day credential. Use it with the current revision to hide your listing or suppress branding. Proof is rechecked after seven days; you can revoke access at any time.
Ownership does not change a technical grade or approve branding. Never put the control credential in the public challenge file.
