api record

Trust and fraud signals for IPs, emails, phone numbers, domains and whole signups. Every tool returns a 0-100 risk_score (higher is riskier) and a verdict of allow, review or block. Prefer score_user when judging a person: it weights the components together and will not average away a hard block on one of them — it bills one lookup per component supplied, and returns billable_lookups so you can see what each call cost. Requires a LayerCall API key sent as `Authorization: Bearer <key>`; a free key covers 1,000 lookups a month — 1,000 single-value calls, or around 250 four-component score_user…

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.

  • lookup_phone unknown never probed

    Validate a phone number worldwide against its national numbering plan. Returns E.164, country, line type (mobile/fixed/VoIP/toll-free/premium) and a risk score. Works globally, not US-only.

    mcp-tool

    {
  "type": "object",
  "required": [
    "phone"
  ],
  "properties": {
    "phone": {
      "type": "string",
      "description": "Number in international form (+14155552671) or national form with country set"
    },
    "country": {
      "type": "string",
      "description": "ISO 3166-1 alpha-2, required only for national-format numbers"
    },

      "maximum": 3,
      "minimum": 0
    }
  }
}
    arguments 21 lines
  • score_device unknown never probed

    Judge a browser fingerprint from /fp.js: headless detection, automation frameworks (Selenium, Puppeteer, Playwright), timezone-versus-IP mismatch and repeat-device history. Note the ceiling honestly — the declared signals it relies on are the first thing stealth tooling patches, so a clean result is weaker evidence than a dirty one.

    mcp-tool

    {
  "type": "object",
  "required": [
    "device_id"
  ],
  "properties": {
    "ip": {
      "type": "string",
      "description": "Visitor IP, so timezone-vs-country can be checked"
    },
    "device_id": {
      "type": "string",
      "description": "Hex fingerprint from /fp.js"
    }
  }
}
    arguments 16 lines
  • score_domain unknown never probed

    Profile a domain: registration date from RDAP, registrar, MX/SPF/DMARC configuration, disposable-mail and risky-TLD detection. newly_registered is null when the age genuinely could not be determined — treat that as unknown, not as 'established'.

    mcp-tool

    {
  "type": "object",
  "required": [
    "domain"
  ],
  "properties": {
    "domain": {
      "type": "string",
      "description": "Bare domain, e.g. example.com"
    }
  }
}
    arguments 12 lines
  • score_ip unknown never probed

    Risk-score an IPv4 or IPv6 address. Detects commercial VPNs (naming the provider where its own published list confirms it), proxies, Tor exit nodes and datacenter hosting, and returns geolocation, ASN and a 0-100 risk score with an allow/review/block verdict.

    mcp-tool

    {
  "type": "object",
  "required": [
    "ip"
  ],
  "properties": {
    "ip": {
      "type": "string",
      "description": "IPv4 or IPv6 address, e.g. 8.8.8.8"
    },
    "strictness": {
      "type": "integer",
      "maximum": 3,
      "minimum": 0,
      "description": "0 lenient, 1 balanced (default), 2 strict, 3 paranoid. Moves the verdict thresholds only; the score is unchanged."
    }
  }
}
    arguments 18 lines
  • verify_email unknown never probed

    Check an email for syntax, MX records, disposable/throwaway providers, role accounts (info@, admin@), homograph lookalikes and domain age. Returns a 0-100 risk score and an allow/review/block verdict.

    mcp-tool

    {
  "type": "object",
  "required": [
    "email"
  ],
  "properties": {
    "email": {
      "type": "string",
      "description": "Full email address"
    },
    "strictness": {
      "type": "integer",
      "maximum": 3,
      "minimum": 0
    }
  }
}
    arguments 17 lines
  • verify_agent unknown never probed

    Cryptographically verify a Web Bot Auth signature (RFC 9421) — proof of WHICH agent is calling, not a guess from the user-agent. Returns verified true/false plus the agent's identity and declared purpose. This is the only check here that proves rather than infers, so it carries no score and no verdict: a verified assistant acting for a real user is usually welcome, a verified scraper usually is not, and that policy is the caller's. Pass the request the agent made to YOU — the signature covers its method, authority and path.

    mcp-tool

    {
  "type": "object",
  "required": [
    "url",
    "headers"
  ],
  "properties": {
    "url": {
      "type": "string",
      "description": "Absolute URL the agent requested from you"
    },
    "method": {
      "type": "string",
      "description": "HTTP method, default GET"
    },
    "headers": {
      "type": "object",
      "description": "Request headers, including signature, signature-input and signature-agent"
    }
  }
}
    arguments 21 lines
  • score_user unknown never probed

    Score an entire signup in one call — any combination of IP, email, phone and domain — returning a single weighted risk score, a verdict, and the top contributing signals. A hard block on any component is never averaged away. This is the tool to use when judging a person rather than a value. Costs one lookup PER COMPONENT supplied, not one per call, so four identifiers cost four; the response reports the exact figure as billable_lookups, and cached components are refunded.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "ip": {
      "type": "string"
    },
    "email": {
      "type": "string"
    },
    "phone": {
      "type": "string"
    },
    "strictness": {
      "type": "integer",
      "maximum": 3,
      "minimum": 0
    },
    "phone_country": {
      "type": "string",

_ 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.

[![measured by brick.blue](https://brick.blue/api/v1/agents/51e9b29600bf27b6/badge.svg)](https://brick.blue/agent/51e9b29600bf27b6)

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.
