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.

  • verify_receipt reads open 1h ago

    Verify an ed25519-signed receipt: the signature, and — unless you pass onChain:false — both txids against an Algorand indexer. Give it an orderId to check one of this service's own orders, or a receipt object to check ANY receipt in this format, including one issued by another server.

  • lookup_phone reads unknown 1h ago

    Identify the country and mobile operator of a phone number and list the top-up offers available for it. Free. The operator is DETECTED from the number range and is a guess: MVNOs (Tesco Mobile, Giff Gaff, Lebara, Voxi, Sky…) resolve to the host network they ride on. Read the detected brand back to the human and have them confirm it before buying, and use `other_brands` to correct it — a voucher bought for the wrong network delivers successfully and cannot be redeemed or refunded.

  • create_pay_link changes data unknown never probed

    Create a checkout link a HUMAN pays from their own Algorand wallet (Pera). Use this when you have no wallet, or when the person should approve and pay themselves: they open the link, see the exact price, sign in their wallet, and the result (the eSIM QR code, or the top-up confirmation) appears on the page. You never hold a key. A top-up link can be paid by anyone — send it to family as 'top up my phone'. An eSIM link delivers to whoever pays. Free. Add `ref` (your Algorand address) to earn a share of margin on each delivered order.

  • buy reads unknown never probed

    Get the x402 payment challenge for a quote. This hosted server holds no wallet, so it does NOT spend your money: it returns the exact amount, asset, payTo address and facilitator for you to pay from your own Algorand wallet, then you POST the quote again with your payment signature. Requires prior human confirmation of the quote. Works the same for a quote from quote_vouchers; the paid response is the batch (batchId and claim links) rather than an order.

  • quote_vouchers unknown never probed

    Lock a price (10 minutes) for a BATCH of travel eSIMs paid in one payment: N claim links, one per person, for a group trip, a conference delegation or event giveaways. Each eSIM is bought when its link is claimed (the person opens it on their phone and installs the QR), and links nobody claims within 30 days are refunded to the paying wallet. Free. Pay the returned quoteId with `buy`, or send the human to this service's /pay/?mode=vouchers page to buy it with their own wallet. Limits: 2–50 eSIMs, each within the per-order limit, the batch within its own limit ($100 by default). ALWAYS show the human the total and the count before buying.

_ try it over mcp through the hub, ceiling 0

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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 13caa806030c608d.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/13caa806030c608d/claim. Over MCP: the claim_endpoint tool.

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.

_ how we knowoff the mcp door
card completeness
100%

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.

spec deviations
0

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.
