# VendSDK Domain Intelligence Bundle

> VendSDK Domain Intelligence Bundle is a paid API for AI agents from vendsdk.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-15).

Runs DNS lookup, TLS certificate check, RDAP/WHOIS query, and HTTP HEAD probe for a domain in a single paid call, returning a unified security and brand-protection report.

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 vendsdk-domain-intelligence-bundle-c319487c
```

Example prompt: Can you run a full domain intelligence check on vendsdk.com — I need the DNS records, TLS certificate details, WHOIS registration info, and HTTP HEAD response all in one shot to evaluate whether it's safe and legitimate?

## When to prefer this

Use this endpoint when you need a comprehensive domain health and security snapshot in a single API call rather than making separate DNS, WHOIS, TLS, and HTTP checks. Ideal for brand protection workflows, phishing investigation, vendor vetting, or security agent pipelines where latency and cost efficiency matter. Prefer it over the sibling single-signal endpoints when you need the full picture at once.

## Known failure modes

- Domain does not exist — DNS lookup fails, partial results returned with ok: false
- TLS certificate missing or invalid — TLS block may be empty or contain error details
- WHOIS/RDAP not available for certain TLDs — whois block may be null or sparse
- Host not responding to HTTP — http_head block may indicate timeout or connection refused
- Invalid hostname input — API returns validation error
- Private or reserved IP space host rejected for SSRF safety

## How this service works

One payment: DNS + TLS cert + RDAP WHOIS + HTTP HEAD for brand protection and security agents

## Output

Returns a JSON object containing: DNS A/AAAA records, TLS certificate subject/issuer/expiry, RDAP/WHOIS registration data (registrar, dates, registrant), and HTTP HEAD response headers and status code — plus a top-level 'ok' boolean and 'host' field identifying the queried domain.
