# AgentDiet Domain OSINT Lookup

> AgentDiet Domain OSINT Lookup is a paid API for AI agents from domain-osint-72343955726.us-central1.run.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Performs open-source intelligence (OSINT) gathering on a domain name, returning structured threat, registration, and infrastructure intelligence.

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-270f1c52
```

Example prompt: Can you run a full OSINT investigation on the domain suspicioussite.io — I want to know who registered it, when, what nameservers it's using, and whether it looks malicious?

## When to prefer this

Choose this endpoint when you need comprehensive open-source intelligence on a domain — including registrar, DNS, hosting, and reputation data — in a single agent-optimized call. It is especially useful for security investigations, vendor vetting, phishing analysis, and competitive research where you want distilled, token-efficient output rather than raw bulk data from multiple separate WHOIS/DNS tools.

## Known failure modes

- Invalid or malformed domain name input returns an error
- Domain not found or unregistered domains may return sparse or empty results
- Rate limiting or payment failure via x402/USDC may block the request
- Private/redacted WHOIS records may limit registrant information
- Network timeouts when querying upstream OSINT sources

## 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 structured JSON response containing agent-ready markdown with OSINT findings about the domain, including registration details, DNS records, hosting infrastructure, and reputation signals. Also includes token compression metadata (raw vs distilled tokens, compression ratio, ROI multiplier) indicating how efficiently the data was distilled for agent consumption.
