api record

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.

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.

  • 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.

    whoisdomain-age

  • 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.

    certificate-transparencycrt.sh

  • 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.

    wayback-machinecdx

  • 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.

_ try it over a2a 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.

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 knowoff the mcp door
card completeness
90%

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.
