The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • match_items unknown never probed

    Which title, channel or fixture is this name? Give a file name, a release name or a playlist entry ("Top.Gun.Maverick.2022.1080p.mkv", "US: ESPN2 HD"); it is cleaned (year, season and episode, quality tags, playlist decorations) and matched by similarity. A matchup ("NFL: Chiefs vs Bills", "Lakers @ Celtics", "Rangers at Celtic 19:45") is answered by the fixture whose two teams those are, kicking off between 36 hours ago and 7 days ahead unless date narrows it. Each result carries a score in 0..1. Use screen for films and TV, channels for television channels, sports for fixtures.

  • add_source unknown never probed

  • search_tlds unknown never probed

    Top-level domains: every label in IANA's root, with type, registry, RDAP server and each registrar's one-year register/renew/transfer price (Porkbun, Dynadot, Cloudflare, OVHcloud). Sorted by renewal by default, because the first year is a promotion. `best` is the cheapest USD price across registrars; with `registrar` it is that registrar's own price in its currency. Answers carry facet counts. `trap: true` keeps only labels that renew at 2x the first year or more.

  • get_tld unknown never probed

    One top-level domain: type, registry, RDAP server, when it entered or left the root, every registrar price (register, renew, transfer, restore, promotions, privacy, restrictions) and its change history.

  • check_domain unknown never probed

    Is a domain name registered? Asks each registry over RDAP. Give `name` as a full name (foo.watches), or a bare word with `tlds` (foo + com,dev,io), or several names comma separated. Each answer is registered (with registrar and expiry), not_registered, or unknown. not_registered means the registry holds no registration; the name may still be reserved or premium, so it is not a promise that it is for sale. unknown (no RDAP server, a timeout, a 429) is never a yes. Each answer carries the cheapest known USD price for its ending.

_ 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.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/7756207bd00fa4f8/badge.svg)](https://brick.blue/agent/7756207bd00fa4f8)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
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.

_ record

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