# DNS, WHOIS & TLS Reconnaissance Lookup

> DNS, WHOIS & TLS Reconnaissance Lookup is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Performs a combined DNS, WHOIS, and TLS certificate reconnaissance query for a given domain name, returning aggregated intelligence about the domain.

## Facts

- Endpoint: GET https://mcp-gateway.agentdiet.dev/v1/dns-whois-tls-recon?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/dns-whois-tls-reconnaissance-lookup-8a8938ba
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Jls8Q16WacZRxtWPcevuG

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dns-whois-tls-reconnaissance-lookup-8a8938ba
```

Example prompt: Can you run a full DNS, WHOIS, and TLS certificate recon on example.com and tell me who owns it, what DNS records it has, and whether its SSL cert looks legitimate?

## When to prefer this

Choose this endpoint when you need a single aggregated call that combines DNS, WHOIS, and TLS certificate data for a domain rather than hitting three separate APIs. It is particularly useful for security investigations, domain vetting, or compliance checks where all three data types are needed together and cost-per-call simplicity (flat $0.01 USDC) matters. Prefer alternatives if you need only one of DNS, WHOIS, or TLS individually, or if you require real-time streaming updates.

## Known failure modes

- Domain not found or unregistered — empty or null WHOIS/DNS data returned
- Invalid domain format — malformed input may yield an error response
- TLS data unavailable for domains without HTTPS — partial results
- Payment not settled — x402 payment required before data is returned
- Rate limiting or gateway errors from upstream DNS/WHOIS providers

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with aggregated DNS records, WHOIS registration details (registrar, registrant, dates), and TLS certificate metadata for the queried domain, along with a status field and a compression ratio proof of work metric.
