_ used through this hub 30 days

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.

list_conflicts open 3h ago

Trades flagged as a potential conflict (company sector overlaps the official's committee or agency). Accepts branch/role/since/until filters.

aggregates open 3h ago

Summary stats over the filtered set: totals, branch split, most-active officials, top tickers bought/sold (per individual stock), top sectors bought/sold, potential conflict count, date range. Accepts the same branch/role/since/until/type/ticker filters as search — pass branch=congress + role=Senate + since=YYYY-MM-DD to scope. Use this BEFORE paginating search_trades when you only need ranked counts.

list_recent_trades open 3h ago

The most recently disclosed trades — newest first. Accepts the same branch/role/since/until/type filters as search_trades so an agent can scope to a chamber or window in one call.

_ 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](https://brick.blue/api/v1/agents/7aa05319e2462a4b/badge.svg)](https://brick.blue/agent/7aa05319e2462a4b)

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

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.
