# AgentDiet Domain OSINT Lookup

> AgentDiet Domain OSINT Lookup is a paid API for AI agents from x402-audit-72343955726.us-central1.run.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Performs open-source intelligence (OSINT) reconnaissance on a domain, returning structured intelligence about registrants, infrastructure, subdomains, and associated threat signals.

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 agentdiet-domain-osint-lookup-a39b4826
```

Example prompt: Can you run a full domain OSINT profile on openai.com — I want to see ownership, DNS records, subdomains, and any threat signals you can surface?

## When to prefer this

Choose this endpoint when you need passive OSINT reconnaissance on a domain — ownership, DNS, subdomains, and threat signals — without active intrusion. Prefer it over generic WHOIS lookups when you need enriched, multi-source intelligence in a single call. It is especially useful for security research, vendor due diligence, phishing investigation, and competitive infrastructure analysis when you want agent-ready, compressed markdown output rather than raw data dumps.

## Known failure modes

- Invalid or malformed domain name returns an error
- Unregistered or non-existent domain yields minimal results
- Rate limiting or quota exhaustion returns 402 or 429 error
- Payment failure via x402/USDC results in 402 Not Authorized
- Heavily privacy-protected or Whois-redacted domains return limited registrant data
- Timeout on slow DNS resolution may return partial results

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output

Returns a JSON object containing structured domain intelligence including WHOIS registrant details, DNS record enumeration, subdomain discovery, hosting infrastructure, associated email contacts, registration dates, and threat/risk signals — delivered as clean agent-ready markdown with token compression metrics (raw vs distilled token counts and compression ratio).
