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://alpha-stream.agentdiet.dev/v1/osint)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, chain details), and an HTTP security header grade/analysis for the target domain — giving a snapshot of the domain's network and security posture.
Example use cases
Pre-deployment security check
“Before we launch, can you check anthropic.com for its TLS certificate issuer, expiry date, and HTTP security header grade so we know if there are any obvious security gaps?”
Vendor due diligence recon
“I need to vet a new vendor — can you pull the DNS resolution, TLS cert details, and security header audit for stripe.com so I can assess their infrastructure security posture?”
Certificate expiry monitoring alert
“Can you inspect the TLS certificate for github.com and tell me exactly when it expires and who issued it, so I can flag it if it's expiring soon?”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined DNS + TLS + HTTP security snapshot for a domain in a single call, particularly for security reconnaissance, vendor assessments, certificate monitoring, or threat intelligence workflows. Prefer this over manual lookups or separate tools when you want structured, machine-readable output covering all three layers (DNS, TLS, HTTP headers) at once.
Side effects
- Domain does not exist or fails DNS resolution — returns empty or error response
- TLS certificate not present or HTTPS not supported — TLS fields may be null or absent
- Domain is unreachable at time of request — may return timeout or partial data
- Invalid domain format provided — returns validation error
- Rate limiting or payment failure (HTTP 402) — request rejected
