Documentation Overview

Trust Score API

Unified trust scoring for domains, wallets, and APIs. Score 0-100 with 5 sub-scores. Powered by x402 micropayments.

The trust layer AI agents need before interacting with unknown services. One API call tells you if a domain, wallet, or endpoint is safe.

What It Scores

Sub-score	Weight	What it checks
SSL/TLS	25%	Certificate validity, HSTS, expiry, issuer, preload
WHOIS	25%	Domain age, registrar reputation, expiry date, suspicious TLDs
Security Headers	20%	CSP, X-Frame-Options, HSTS, Referrer-Policy, Permissions-Policy, X-Content-Type-Options
DNS	15%	A/AAAA/MX/NS records, SPF, DMARC, DNSSEC
Content	15%	Reachability, latency, status code, robots.txt, favicon, CORS

For wallet addresses (0x...): transaction count, ETH/USDC balance, contract detection on Base L2.

Endpoints

    { "target": "sketchy-site.tk", "compositeScore": 15, "grade": "F", "verdict": "dangerous" }
  ]
}

Grading Scale

Score	Grade	Verdict	Meaning
90-100	A+	trusted	Excellent security posture, well-established
75-89	A	trusted	Good security, minor improvements possible
60-74	B	moderate	Acceptable, some security gaps
40-59	C	moderate	Below average, multiple issues
20-39	D	suspicious	Poor security, use with caution
0-19	F	dangerous	Critical issues, avoid interaction

Use Cases

Before payments: Check if an API or wallet is trustworthy before sending USDC
Agent safety: Verify domains before scraping, crawling, or sending data
Due diligence: Compare multiple service providers
Phishing detection: Score suspicious URLs from emails or messages
Wallet vetting: Check on-chain reputation before transacting

MCP Integration

Works with Claude Desktop, Cursor, Copilot, and any MCP-compatible client.
