How this service works
Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade. (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/osint)
Output
Returns live DNS resolution data (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security header grade/breakdown indicating which security headers (e.g. HSTS, CSP, X-Frame-Options) are present or missing for the target domain.
Example use cases
Vendor security due diligence check
“Before we integrate with this new vendor, can you check the TLS certificate details, DNS resolution, and HTTP security headers for their domain stripe.com so I can assess their basic security posture?”
SSL expiry monitoring for owned domains
“Can you inspect the TLS certificate for mycompany.com and tell me when it expires and who issued it? I want to make sure we're not about to let it lapse.”
Phishing domain investigation
“I received a suspicious email from someone claiming to be from paypa1.com — can you do a DNS and TLS certificate recon on that domain so I can see if it's a legit site or a phishing setup?”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call recon on DNS, TLS, and HTTP security headers for a domain without stitching together multiple separate tools. It is ideal for security due diligence, vendor assessments, phishing investigations, certificate expiry checks, or any workflow that needs a quick infrastructure fingerprint of a domain. Prefer this over generic whois or passive DNS tools when live, real-time resolution and certificate inspection are required.
Side effects
- Domain does not exist or fails DNS resolution — returns empty or error DNS result
- Domain's server is unreachable or times out during TLS/header inspection
- Invalid or malformed domain name input — validation error returned
- Domain has no TLS certificate (HTTP-only) — TLS fields may be null or absent
- Rate limiting or payment failure (HTTP 402) if credit is exhausted
