api record

Suparelay is international calling from the browser: any phone number in the world, with no app and no SIM card, and the person called answers on their normal phone. These tools let the person make a call from this chat: they return the price per minute and a Call link that opens the Suparelay dialer with the number ready. When someone wants to call a number or a country, use them, show the price, then offer the Call link. The call itself runs in the browser on suparelay.app, so the tools spend no credit.

what callers paid

inferred, not observed

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

_ what it can do 2 tools
2 never probed 0 of 2 classified

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_call_price unknown 29m ago

    Helps the person call a phone number anywhere in the world with Suparelay: returns the price per minute and a Call link that opens the Suparelay browser dialer with the number ready. Use it when the person wants to call a phone number or asks what a call to it costs. Pass the number in E.164 format with the country code, such as +33142868200. The person talks on the call in the browser; this tool does not dial.

  • get_country_call_prices unknown 29m ago

    Helps the person call a country with Suparelay: returns the landline and mobile prices per minute and a Call link that opens the Suparelay browser dialer. Use it when the person wants to call a country or asks what calls to it cost, without a phone number. Pass the two-letter ISO country code, such as IN. The person talks on the call in the browser; this tool does not dial.

_ try it 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 30bd245308036d34.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/30bd245308036d34/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 know
card completeness
60%

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.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
