https://live-entity-verification-production.up.railway.app
Registry code: 928aa1f0a67db927
Cross-signal Bayesian corroboration of entity existence, fusing WHOIS, Certificate Transparency, Wayback Machine, and DNS operational maturity into a calibrated hallucination verdict. x402 pay-per-call, tiered $0.01-$0.05 USDC on Base Sepolia by route.

- Is nexus-live-entity-verification live?
- Yes — it answered the hub's last check (checked 8h ago). It answered 100% of checks over the last 30 days.
- Is nexus-live-entity-verification free to use?
- Not measured yet.
- What tools does nexus-live-entity-verification have?
- 5 tools: Certificate Transparency Presence Probe, Wayback Snapshot Density Meter, DNS Operational Maturity Auditor, Cross-Signal Entity Existence Verification, WHOIS Registration Timeline Resolver.
- Is nexus-live-entity-verification safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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 from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
probe_certificate_transparency_presence unknown never probed
Searches crt.sh CT logs for certificates issued for a domain. Computes certificate count, issuance date range, unique issuers, subdomain count, and continuity score.
measure_wayback_snapshot_density unknown never probed
Measures Wayback Machine CDX snapshot density over a lookback window. Returns total snapshots, first/last dates, snapshots per year, density score, and coverage gaps in months.
audit_dns_operational_maturity unknown never probed
Audits DNS operational maturity: MX, SPF, DMARC, DKIM selectors, NS record count, and propagation consistency across resolvers. Returns maturity score and component signals. DNS maturity alone is not sufficient for a VERIFIED_LIVE verdict per the cross-signal spec.
verify_entity_existence_cross_signal unknown never probed
Fuses WHOIS, CT, Wayback, and DNS signals with Bayesian calibrated weights. Returns corroborated existence verdict, hallucination probability, and failure mode classification. Fail-closed: insufficient corroboration returns a blocking verdict rather than an ambiguous null.
resolve_whois_registration_timeline unknown never probed
Resolves WHOIS registration timeline. Returns creation, expiration, updated dates, registrar, registrant country, age in days, and historical registrant count where available.
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 id928aa1f0a67db927.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/928aa1f0a67db927/claim.
Over MCP: the claim_endpoint tool.

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.
