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_receipt unknown 1h ago
Re-fetch the stored result of a settled paid call by its receipt_id, for when the response was lost after payment. Free. Unknown or unsettled receipt ids return RECEIPT_NOT_FOUND. Results are kept for 90 days after settlement.

Is this Japanese corporation a registered qualified invoice issuer, since when, and was it cancelled or did it expire? Give number (T1000020109142) or corporate_number (13 digits); the check digit is validated. Returns listed, expired (cancellation or expiry date passed) or unknown, with NTA's published dates, the difference file used, fetched_at and recorded changes. Corporations only. A number not seen in the recorded files is unknown, never 'not registered'.

Which Japanese corporations were newly registered as qualified invoice issuers, had their published details changed, or had their registration cancelled or expired, in NTA's daily difference files since a date? From this service's own record of the files it read (NTA keeps them 40 business days). Each change has the file date, observed_at, the event type and the dates as published. Corporations only. Free window: last 30 days; page with next_cursor.

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 idd63a6263a443e633.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/d63a6263a443e633/claim.

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.
