# 1gateway Site Profile

> 1gateway Site Profile is a paid API for AI agents from 1gateway.dev, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-10).

Returns a comprehensive profile of a website including HTTP status, HTTPS/redirect behavior, security headers, DNS, mail provider, SPF/DMARC, RDAP registrar info, robots.txt, and page metadata in a single call.

## 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 1gateway-site-profile-e1e5ce63
```

Example prompt: Can you pull a full site profile for stripe.com — I want to see if it has HTTPS, what security headers it sets, who the registrar is, how old the domain is, and whether it has an llms.txt or robots.txt?

## When to prefer this

Choose this endpoint when you need a single-call, comprehensive vetting of a website covering security, DNS, email authentication, domain provenance, and page metadata simultaneously — particularly for lead research, vendor due diligence, or security audits. Prefer it over separate DNS or WHOIS tools when breadth matters and you want everything in one response.

## Known failure modes

- Private or internal IP targets return HTTP 400 and are not charged
- Invalid or unreachable domains may return DNS resolution errors
- Sites with aggressive bot blocking may return incomplete page metadata
- Domains without RDAP records will have null registrar/age/expiry fields
- Timeout on slow-responding servers may yield partial results

## How this service works

Use when an agent must vet or research a website in one call (lead research, security or SEO check, is this site legit). Input: url or bare domain. Output: JSON page metadata, HTTP status, HTTPS and HTTP-to-HTTPS redirect, server and hosting hints, 7 security headers, robots.txt (sitemaps, AI-crawler rules), llms.txt presence, plus domain DNS, mail provider, SPF/DMARC and RDAP registrar, age and expiry. Example: ?url=stripe.com

## Output

A JSON object containing: final URL after redirects, HTTP status code, HTTPS availability flag, HTTP-to-HTTPS redirect flag, server and tech hints, 7 security headers (CSP, HSTS, X-Frame-Options, etc.), robots.txt content including sitemap URLs and AI-crawler directives, llms.txt presence, page metadata (title, description, OG tags, JSON-LD types, favicon, hreflang alternates), DNS details, mail provider, SPF and DMARC records, RDAP registrar name, domain registration age, and domain expiry date.
