TrustSource SSL/TLS Certificate Intelligence
x402
TrustSource SSL/TLS Certificate Intelligence is a paid API for AI agents from api.trustsource.cc, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).
Analyzes a domain's SSL/TLS certificate and returns a 0–100 trust score, tier classification, chain details, expiry info, signature algorithm, TLS protocol version, and cipher quality.

How this service works
Check whether a domain's TLS/SSL certificate is valid, trusted, and not expiring before connecting to it. Performs a live handshake and returns a 0–100 score and tier (VALID/WEAK/EXPIRING/EXPIRED/UNTRUSTED/INVALID) with chain trust, days-to-expiry, signature algorithm, TLS version, and cipher quality. Use before submitting credentials, posting to a webhook, or following a payment link, to catch expired, self-signed, or MITM-risk certificates.
Output
Returns a 0–100 SSL/TLS trust score, a tier label (VALID, WEAK, EXPIRING, EXPIRED, UNTRUSTED, or INVALID), full certificate chain details, expiry timestamp, signature algorithm, TLS protocol version in use, and an assessment of cipher suite quality.
Example use cases
Monitor customer-facing domains for certificate expiry
“Check the SSL certificate status for all our payment processor domains — I need to know if any are expiring soon, their current trust scores, and whether they're using weak ciphers or outdated TLS versions.”
Audit third-party vendor HTTPS security
“I need you to analyze the SSL certificates for our top five API vendor endpoints and give me their trust scores, tier classifications, and cipher suite quality — flag anything that's WEAK, EXPIRING, or using poor TLS protocols.”
Detect compromised or spoofed domains
“Can you check the SSL certificate trust score for these three domains that claim to be from our partner — I want to make sure their certificates are VALID, their chains are intact, and they're not UNTRUSTED or INVALID.”
Technical details
Endpoint
GEThttps://api.trustsource.cc/sslcheckWhen to prefer
Use this endpoint when you need structured, scored SSL/TLS certificate intelligence about a domain — specifically when you need the tier classification (VALID/WEAK/EXPIRING/EXPIRED/UNTRUSTED/INVALID), expiry awareness, cipher quality, and TLS protocol version all in a single call. Prefer this over generic WHOIS or HTTP header checks when the focus is certificate chain integrity and TLS configuration quality.
Side effects
- Domain not reachable or does not serve HTTPS — may return INVALID tier or error
- Domain has no SSL certificate at all — returns INVALID or UNTRUSTED tier
- Malformed domain input — likely returns a 400-level validation error
- Network timeout reaching the target domain — may return an error or null score
- Self-signed certificates flagged as UNTRUSTED with low score
