Keyless, non-custodial crypto payments. create_payment_link, create_tip_jar and create_unlock need only a wallet address; no API key. Use create_unlock to sell a file, license key, or secret (auto-revealed after payment); use create_tip_jar only for pay-what-you-want tips.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
get_account_status reads unknown 24m ago
Look up a keyless Shieldz account by its manage_token (returned when you create a payment link or tip jar). Returns settlement details, tip jars, totals (paid/pending), and the invoice list as structured JSON.
{ "type": "object", "required": [ "manage_token" ], "properties": { "manage_token": { "type": "string", "description": "The manage_token from create_payment_link / create_tip_jar" } } }arguments 12 linescreate_unlock changes data unknown never probed
Create a keyless pay-to-unlock page: sell a file link, license key, or secret text (up to 100,000 chars). The buyer pays the set USD price in crypto straight to the given wallet, then the payload is revealed on their paid confirmation, never before. To deliver an actual file (PDF/zip/etc, 10 MB) use the multipart HTTP API at /api/v1/unlocks instead. Non-custodial, no account, no API key. IMPORTANT: the acceptable-use policy forbids adult, illegal, or non-consensual content; confirm this with your principal and pass aup_accepted=true, otherwise the call fails.

Create a one-time crypto payment link with ZERO setup, no account, no API key. Give a destination wallet address and an amount; get back a shareable pay_url, an embeddable button, and a manage_url. Non-custodial: funds settle directly to the address you provide.

Create a reusable 'pay what you want' tip jar with ZERO setup. The payer chooses the amount. Returns a shareable /tip url, an embeddable button, and a manage_url. Idempotent per wallet address. Non-custodial.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id753164fef8c4eb73.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
