PriceFeed
Registry code: 3a5d69b3721278bf
PriceFeed serves real-time and historical crypto & fiat exchange rates aggregated by median from multiple independent sources (Binance, Kraken, Coinbase, OKX, WhiteBIT, NBU, ECB, NBP, Monobank and others). Supported assets include BTC, ETH, USDT, USDC, BNB, SOL, USD, EUR, UAH, PLN, GBP. Responses marked "stale": true come from the fallback cache because upstream sources are temporarily unavailable. Rates never trigger external API calls — they are always served from the aggregation layer, typically updated every minute for crypto and every 6 hours for fiat.

what callers paid
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_service_status reads open 8h ago
Get PriceFeed service health: data source statuses, cache health and the list of supported currency pairs.

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 id3a5d69b3721278bf.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/3a5d69b3721278bf/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.
