Does NOT screen the other 34 states or licensure board actions. Every result states why it matched.

- What tools does CF Exclusion Check have?
- 3 tools: exclusion_sources, exclusion_batch_check, exclusion_check.
- Is CF Exclusion Check safe to connect?

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 5 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

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.
exclusion_sources unknown never probed
List the loaded exclusion sources (OIG LEIE and SAM.gov), their row counts, load dates, load completeness and whether a bulk reseed is due. Free. Screening itself is paid: exclusion_check per name, or exclusion_batch_check for 2-200 at once ($0.30/$1.00/$3.00 by size).
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesexclusion_batch_check unknown never probed
Screen 2-200 people/businesses against the same sources as exclusion_check in one call. Tiered price by item count: $0.30 (2-10), $1.00 (11-50), $3.00 (51-200), charged once via x402. An invalid item is reported in place, not a failure; all-invalid is refused before charging.

Screen a person or business against the HHS-OIG List of Excluded Individuals and Entities (LEIE) AND the SAM.gov exclusions list. Costs $0.05 per call via x402. Returns a verdict, a confidence level, the basis of each match, and the reason it matched. A match is a name match unless it was made on an identifier (npi, uei, cage); it is not an identity determination.

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 agent card — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id69ef1e4059876a50.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/69ef1e4059876a50/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.
How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
